Classification and marking of steels, cast irons, non-ferrous metals and alloys

Marking and decoding of carbon steels of ordinary quality

Steels contain increased amounts of sulfur and phosphorus. Marked St.2kp., BSt.3kp, VSt.3ps, VSt.4sp. They are deciphered as follows: St is the index of a given steel group, numbers from 0 to 6 are the conditional number of the steel grade. As the grade number increases, the strength of the steel increases and the ductility decreases. An example of such steels containing carbon, sulfur and phosphorus is shown in the table below.

According to guarantees upon delivery, there are three groups of steels: A, B and C. For steels of group A, mechanical properties are guaranteed upon delivery; the index of group A is not indicated in the designation. For steels of group B, the chemical composition is guaranteed. For group B steels, both mechanical properties and chemical composition are guaranteed upon delivery. The indices kp, ps, sp indicate the degree of deoxidation of the steel: kp - boiling, ps - semi-calm, sp - calm.

Marking and decoding of alloy steels

Designation is alphanumeric. Alloying elements have symbols - they are designated by letters of the Russian alphabet.

Designations and interpretation of letters of alloying elements of steels

A – nitrogen (indicated in the middle of the mark) B – niobium C – tungsten D – manganese D – copper E – selenium K – cobalt M – molybdenum N – nickel P – phosphorus P – boron C – silicon T – titanium F – vanadium X – chromium C – zirconium Yu – aluminum Ch – rare earth

Alloy structural steels

At the beginning of the stamp there is a two-digit number indicating the carbon content in hundredths of a percent. Alloying elements are listed below. The number following the symbol of the element shows its content as a percentage; if there is no number, then the content of the element does not exceed 1.5%. Steel 30Х2М. This grade of steel contains about 0.30% carbon, 2% chromium, and less than 1% molybdenum.

Alloy tool steels

At the beginning of the brand there is a single-digit number indicating the carbon content in tenths of a percent. If the carbon content is more than 1%, the number is not indicated; then alloying elements are listed, indicating their content.

Non-standard steel designations

— High-speed tool steels are deciphered as follows

P is the index of this group of steels (from rapid - speed), then a number indicating the content of the main alloying element - tungsten. Carbon content more than 1%. All high-speed steels contain about 4% chromium, so it is not specified. If steels contain an alloying element, then their content is indicated after the designation of the corresponding element. Steel R6M5 In this steel the tungsten content is 6%, molybdenum is 5%.

Ш – index of this group of steels. X - indicates the presence of chromium in the steel. The next number shows the chromium content in tenths of a percent. Carbon content more than 1%. Steel ШХ6, steel ШХ15ГС. These steels contain, respectively, 0.6% and 1.5% chromium.

The letter “A” at the end of the mark indicates high-quality steel (30KhGSA), in the middle of the mark - nitrogen, at the beginning of the mark - automatic steel (A35G2). Particularly high-quality steel is designated by the letters Ш, ВД, VI, PD, etc. at the end of the brand name, where VD means that the steel or alloy was produced by vacuum-arc remelting, Ш - by electroslag remelting, VI - by vacuum-induction melting, PD - by plasma-arc melting, etc. High-alloy steels of complex composition are sometimes designated by the serial number of development and development on).

Designation of cast iron grades

Different grades of cast iron are designed to be used for different purposes. The main ones are the following:

1. Pig irons. They are designated as “P1”, “P2” and are intended for remelting in steel production; cast iron with the designation “PL” is used in foundries for the manufacture of castings; conversion with a high phosphorus content, designated by the letters “PF”; High quality pig material is designated by the abbreviation “PVK”.
2. Cast iron, in which graphite is in plate form - “SC”.
3. Anti-friction cast iron: gray – “ACS”; high strength - “AChV”; malleable - "AChK".
4. Cast iron with nodular graphite, used in foundries, is “HF”.
5. Cast iron with alloying additives, endowed with special properties - “C”. Alloying elements are designated by letters in the same way as for steel. The designation with the letter “Ш” at the end of the name of the cast iron grade indicates the spherical state of the graphite in such a grade.
6. Malleable cast iron – “KCH”.

General classification of steels

Steel is an alloy of iron and carbon (up to 2% carbon). According to the chemical composition, steel is divided into:

• carbon;
• alloyed;

According to quality, steel is divided into:

• ordinary quality steel;
• quality;
• improved quality;
• high quality

Carbon steel of ordinary quality is divided into three groups:

• A - supplied according to mechanical properties and used mainly when products made from it are subjected to hot processing (welding, forging, etc.), which can change the regulated mechanical properties (St0, St1, etc.);
• B - supplied by chemical composition and used for parts subjected to such processing in which the mechanical properties change, and their level, in addition to the processing conditions, is determined by the chemical composition (BSt0, BSt1, etc.);
• B - supplied according to mechanical properties and chemical composition for parts subject to welding (VSt1, VSt2, etc.).

Classification of carbon steels

Steels are divided into carbon and alloy. According to their intended purpose, a distinction is made between structural steels with a carbon content of hundredths of a percent and instrumental steels with a carbon content of tenths of a percent. The largest volume of welding work involves the use of low-carbon and low-alloy structural steels.

The main element in carbon structural steels is carbon, which determines the mechanical properties of steels in this group. Carbon steels are smelted of ordinary quality and high quality. Carbon steels of ordinary quality are divided into three groups:

• group A - for mechanical properties;
• group B - according to chemical composition;
• group B - according to mechanical properties and chemical composition.

The following grades of steel are produced:

• group A - St0, St1, St2, St3, St4, St5, St6;
• group B - BSt0, BSt1, BSt2, BSt3, BSt4, BSt5, BSt6;
• group B - VSt0, VSt1, VSt2, VSt3, VSt4, VSt5.

According to the degree of deoxidation, ordinary quality steel has the following designation:

• kp - boiling,
• ps - semi-calm,
• sp - calm.

Boiling steel containing silicon (Si) no more than 0.07% is obtained by incomplete deoxidation of the metal with manganese. Steel is characterized by a pronounced uneven distribution of harmful impurities (sulfur and phosphorus) throughout the thickness of the rolled product. Local increased concentration of sulfur can lead to the formation of crystallization cracks in the weld and heat-affected zone. Boiling steel is prone to aging in the heat-affected zone and transition to a brittle state at subzero temperatures.

Calm steel is obtained by deoxidation with manganese, aluminum and silicon, and contains silicon (Si) of at least 0.12%; sulfur and phosphorus are distributed more evenly in it than in boiling steel. This steel is less prone to aging and has less reaction to welding heat.

Semi-quiet steel, in terms of its tendency to aging, occupies an intermediate place between boiling and calm steel. Semi-quiet steels with grade numbers 1–5 are smelted with normal and high manganese content, up to approximately 1%. In the latter case, the letter G is placed after the brand number (for example, BStZGps).

Group A steels are not used for the manufacture of welded structures. Group B steels are divided into two categories. For steels of the first category, the content of carbon, silicon, manganese is regulated and the maximum content of sulfur, phosphorus, nitrogen and arsenic is limited; For steels of the second category, the maximum content of chromium, nickel and copper is also limited.

Group B steels are divided into six categories. The full designation of steel includes grade, degree of deoxidation and category number. For example, VStZGps5 means the following: steel group B, grade StZG, semi-quiet, category 5. The composition of steels of group B is the same as that of steels of the corresponding grades of group B, 2nd category. Steels VSt1, VSt2, VStZ of all categories and degrees of deoxidation are produced with guaranteed weldability. Steels BSt1, BSt2, BStZ are supplied with a guarantee of weldability at the customer’s request.

High-quality carbon steel is produced in accordance with GOST 1060-74. Steel has a low sulfur content. Permissible deviation for carbon (0.03-0.04%). Steels with a carbon content of up to 0.20%, inclusive, can be boiling (kp), semi-quiet (ps) and calm (sp). The rest became only calm. For subsequent mild steels, the letters “sp” are not placed after the numbers.

Carbon steels in accordance with OST 14-1-142-84 are divided into three subclasses:

• low-carbon with carbon content up to 0.25%;
• medium-carbon with carbon content (0.25-0.60%);
• high-carbon with a carbon content of more than 0.60%.

Cast iron

Cast iron is an alloy of iron and carbon with a content of the latter above 2.15%. It is divided into unalloyed and alloyed containing manganese, chromium, nickel and other alloying additives.

Differences in structure divide cast iron into two types: white (has a silvery-white fracture) and gray (has a characteristic gray fracture). The form of carbon in white cast iron is cementite. In gray - graphite.

Gray cast iron is divided into several varieties:

• malleable;
• heat resistant;
• high strength;
• heat resistant;
• antifriction;
• corrosion resistant.

Steel grades - explanation, types, table with explanations

When starting to create a product, designers develop its design, select steel grades, and analyze them based on their properties. The mechanism is required to be able to operate under given conditions. Considering the structure in dynamics, they try to establish what loads will arise in one or another part.

Based on the calculations, the requirements for the strength of the elements are determined. Then a material is selected that can experience repeated loading, as well as abrasive effects. The higher the load, the less choice the designer has. The result of the design is the creation of a real prototype in metal, it is tested according to methods accepted in the industry. If necessary, the selection of steels used at the design stage is adjusted. In practice, the most common materials used to create machines, devices and complex mechanisms are steel.

Steel classification

To understand the markings, you need to understand how steel alloys are classified according to their intended purpose. It is customary to determine properties according to several parameters:

1. The chemical composition determines the strength indicators. Here the properties are determined by the compositional ratios between iron and carbon. Along the way, changes in characteristics depend on the presence of alloying elements or substances that impair performance.
2. The structure changes depending on the production methods. Forged products are stronger, cast ones may form pores or other defects. When rolling through rollers, hardening is achieved and the desired shape is obtained.
3. For proper use, certain brands are determined by their intended purpose. Such information is especially important for special-purpose steels. In them, even small changes in the chemical composition can significantly change the behavior under load or operation in an aggressive environment.
4. The quality of steel ingots depends on the content of harmful components. Sulfur and phosphorus lead to cold brittleness and red brittleness, so metallurgists try to remove deteriorating ingredients from the alloy.
5. Oxygen in steel products changes the structure. To remove it, deoxidizers are added to the molten mass; they form oxides and do not cause negative changes to the metal.

Classification of steels according to main indicators

Classification by structure

The structure is studied on special thin sections. They are examined under a microscope, having previously treated the polished surface with sulfuric acid. It is customary to define the following states:

• Hypoeutectoids are characterized by a high ferrite content. Low carbon content does not allow the metal to exhibit sufficient resistance under mechanical loads;
• eutectoid correspond to the best ratio between strength and plastic properties;
• hypereutectoid steels are used in the manufacture of tools. They are distinguished by high surface hardness, as well as resistance to loading;
• ledeburite contain carbides. The metal exhibits excessive fragility;
• Ferritic indicators correspond to the properties inherent in pure iron.

Ledeburite. Iron carbide inclusions are visible

To improve properties, normalization is carried out. It consists of relieving stress from parts that have had heat treatment associated with improved properties. Prolonged heating and holding at temperatures above 720...750 °C, and subsequent cooling leads to annealing. Metal grains change their appearance.

The top row shows the sections before normalization, and the bottom row shows them after

Alloying - the mechanism of action of alloying elements

It is difficult to decipher steels. Materials science studies this subject comprehensively.

The content of alloying additives in steel can vary within wide limits, depending on what properties need to be imparted to the metal. Thus, nickel and chromium can be present in steel in amounts up to 1%, in some cases more. Molybdenum, vanadium, titanium and niobium - 0.1-0.5%, manganese and silicon - from 1% or more.

The impact of alloying additives in any case is associated with distortion of the iron crystal lattice and the introduction of foreign atoms of a different size into it.

How is it easier to decipher steels (materials science)? The table provides useful information.

Element	Designation	Chem. sign	Influence of an element on the properties of metals and alloys
Nickel	N	Ni	Nickel imparts corrosion resistance to alloys through strengthening the bonds between the nodes of the crystal lattice. The enhanced hardenability of such alloys determines the stability of properties over a long period of time.
Chromium	X	Cr	Improvement in mechanical properties - increased strength and yield - is due to an increase in the density of the crystal lattice
Aluminum	YU	Al	It is fed into the metal stream during casting for deoxidation, most of it remains in the slag, but some of the atoms pass into the metal and distort the crystal lattice so much that this leads to a multiple increase in strength characteristics.
Titanium	T	Ti	It is used to increase the heat resistance and acid resistance of alloys.

Features of steel marking

Structural steels

Conventional steels contain carbon. The presence of alloying elements is not controlled. In practice, structural steels of ordinary quality are most often used. They are used everywhere. They are used for the production of rolled metal. Designated by indicating the approximate carbon content of the alloy. The most common brands are shown in table. 1.
