Letter designations of steels and their interpretation
The chemical composition of many alloyed structural steels is determined by GOST 4543–71 “Rolled products from alloyed structural steel. Technical conditions". The same standard defines the basic letter symbols for designating alloying elements. It must be taken into account that steels are currently produced with additions of elements, the designation of which is not provided for by the standard. In this case, the elements in the steel grade are usually designated by the first letters of the name.
The symbolic letter designations of the main alloying elements are given below.
- A – nitrogen*
- B – niobium
- B – tungsten
- G – manganese
- D – copper
- E – selenium
- K – cobalt
- L – beryllium*
- M – molybdenum
- N – nickel
- P – phosphorus
- R – boron*
- C – silicon
- T – titanium
- F – vanadium
- X – chrome
- C – zirconium
- Ch – RZM
- Yu – aluminum
- Ш – magnesium*
* – if the letter is in the middle of the marking, for example 16G2AF
Description
Steel 110G13L is used : for the manufacture of castings for vortex and ball mill housings, jaws and cones of crushers, tram and railway switches and crosses, caterpillar tracks, sprockets, excavator bucket teeth and other parts subject to impact wear; parts of mill linings of mining and metallurgical equipment; point crosspieces of switches of grades 1/11 and 1/9 for rails of types P75, P65, P50 with cast cores.
Note
High-manganese wear-resistant steel of austenitic class. Steel has a high resistance to wear when simultaneously exposed to high pressures or shock loads.
Applications of Hadfield steel
Hadfield steel is used in many industries , as it has very important and useful qualities.
When making products from this material, you can be sure that it will not fail, since the strength and other positive qualities of Hadfield steel are undeniable. High wear resistance and strength directly influenced the popularity of this material. Various enterprises involved in the manufacture of different types of products used this material, since it was this steel that could provide the necessary strength to the product.
Therefore, it is not at all surprising that Hadfield steel is used in the manufacture of a huge number of different products. With its help, track tracks of tanks (as already mentioned above), cars, tractors, rail crosspieces, jaws of crushers, turnouts, which are capable of working under severe conditions of abrasion and shock loads, are made. In addition, it is Hadfield steel that is used to make window bars for prisons .
By the way, an interesting fact can be said about the last point. The fact is that the use of Hadfield steel to make window bars for prisons is jokingly called a mockery of prisoners. The fact is that a classic escape involves using a hacksaw to cut a metal grate, after which you can escape. History has recorded a huge number of such escapes according to a banal scenario using a hacksaw to cut metal. By the way, an interesting fact: according to prison guards, it is hacksaws that take first place in the top items that friends and relatives try to smuggle to prisoners.
And if in the case of using a hacksaw in relation to ordinary window bars, the prisoners still had some chances for salvation, then the use of Hadfield steel simply does not leave them. The fact is that this steel, unlike others, has a very interesting property, which is that in the process of cutting the grating rods, a strong hardening of the surface that is affected occurs. This affects the hardening of the steel , increasing its hardness to the hardness of the hacksaw itself and even higher. As a result, one should not even hope for a positive result from such a futile enterprise.

A typical example of the use of 110G13 steel: the steel is used for electroslag surfacing - the production of bimetallic crusher beaters (the base is low-carbon steel). The technology of electroslag surfacing involves the use of a consumable nozzle with a feed of Sv-08 electrode wire with a diameter of 4 mm and a charge material consisting of a mixture of blast furnace and electroferromanganese in a ratio of 4:1. The charge is fed through a disc feeder driven by a wire feed mechanism. Surfacing mode: Iс = 630 A; Uc = 22 V; hs =30 mm; ve = 104 m/h; feeder capacity 50 g/min.
The depth of penetration of the base metal is 3-5 mm. A layer with a cross section of 25 X 40 mm is fused along the length of the beater 850 mm. The initial and final sections of the deposited layer are removed by gas cutting, immersing the beater in water to eliminate the possibility of overheating the layer. The cut areas are cleaned with an emery wheel.
Chemical composition of the deposited layer: 0.9-1.1% C; 13.5 - 14% Mn; 0.4-0.5% Si; 0.018-0.023% S; 0.08-0.09% R. The electroslag process provides a more favorable thermal cycle compared to the arc process, and a lesser tendency to form hot cracks. The durability of the blows increases by 8-9 times.
The technology of simultaneous horizontal electroslag surfacing of a series of mine mill beaters is of interest. After cleaning the welded surface, the beaters are placed in special conductors attached to a closed conveyor belt. Copper spacer plates 10 mm thick are installed between them. The welded surface of the beaters and copper spacers form a continuous strip onto which the charge and flux are supplied. The flux-charge-flux layer is melted with a comb of low-carbon wires fed by a surfacing apparatus. The following is the surfacing mode:
Current strength, A | 2500—3500 |
Voltage, V | 32—36 |
Number of wires, pcs. | 6 |
Wire diameter, mm | 3 |
Speed, m/h: surfacing wire feed | 120 3.4 |
Material consumption per blower (Stalinite alloy), kg: ferrochrome ferromanganese wire Sv-08A flux AN-348-A | 0.46 0.38 1.1 0.2 |
With horizontal electroslag surfacing, most operations are mechanized. Further improvement of surfacing technique and technology, as well as increasing the dimensional accuracy of blow blanks, can make it possible to fully automate the surfacing process. The wear resistance of welded blows is 3 times higher than that of non-surfaced ones. After the completion of the surfacing operation, the copper spacer plates are removed and the beaters are separated from one another.
An industrial installation U-305 with a power source TSHN-15 was developed and manufactured, on which cast iron and steel rolls of a strip mill “300” and two wire mills “250-1” and “250-2” are deposited. Electroslag surfacing is carried out with tubular electrodes D 300 mm, centrifugally cast from alloy cast iron. The length of the roll barrel is 450 mm, the total length is 1400 mm, the material of the roll is nodular cast iron. The working layer is bleached chromium-nickel cast iron of the Nihard type with the following composition: 2.8% C; up to 0.3% Si; 0.6% Mn; 0.8% Cr; up to 3.8% Ni; up to 0.55% P and up to 0.11% S. The hardness of the working layer of bleached cast iron is HB 560-630, the layer thickness is 25-35 mm. It is 2.5-3.5 times the thickness of the permissible wear.
For surfacing rolls, ANF-14 flux is used. The process can be started using the liquid start principle or using a special mixture containing ANF-14 flux, steel shavings and mill scale. Some parameters of the surfacing mode are given in the table below.

Serial numbers of the table. 9.61 correspond to the numbers in table. 9.60.
A study of the microstructure of the deposited layer (No. 3, Table 9.60) showed that it is quite complex and consists of martensite, lower bainite, pearlite, residual alloyed austenite and a cementite component.

The durability of deposited rolls is 2-3 times higher than that of cast iron two-layer rolls. High-alloy steels and copper-based alloys are used as anti-corrosion coatings applied by electroslag surfacing. The most satisfactory results were obtained with electroslag surfacing with minimal penetration of the base metal.
