Heat treatment

Steel 40ХН2МА – medium-carbon alloyed hypoeutectoid steel.
Heating hardened steels to temperatures not exceeding A1 is called tempering. Complex heat treatment consisting of full hardening (steel is heated to a temperature above A3) and high tempering

(500-680 °C) structural steels are called improvement. Improvement of this steel, in contrast to normalization, provides an increased yield strength in combination with good ductility and toughness, and high resistance to crack development. In addition, the cold brittleness threshold is reduced.

For this steel, the optimal heat treatment mode is quenching at 850°C. Hardening is carried out in water, followed by tempering at 620°C in oil.

Decoding

Decoding of steel 40ХН2МА includes information:

• 40 – 0.4% carbon;
• X – less than 1% chromium;
• H2 – 2% nickel;
• M – up to 1% molybdenum;
• A – high quality steel (minimum amount of sulfur and phosphorus in the composition).

This is a strong, tough metal, which during heat treatment is calcined to a considerable depth. Alloying components are designed to improve strength and durability, and molybdenum facilitates heat treatment.

Chemical composition

The alloy contains a maximum of:

Each of the components improves the characteristics of 40ХН2МА steel. Chromium and nickel provide hardness and corrosion resistance, copper - viscosity and thermal conductivity, manganese and silicon - bind free iron, reduce the influence of sulfur and phosphorus.

The main physical characteristics of the metal are:

• electrical resistivity;
• Young's modulus;
• density (7850 kg/m3);
• heat capacity;
• coefficient of thermal conductivity and thermal expansion.

Depending on the heating during testing, the results may vary. This allows you to determine the optimal area of ​​operation of the structure.

Application

Structural steel 40ХН2МА is not subject to brittle fracture after tempering, which is due to the presence of molybdenum. Due to its high strength, the material can be used for the production of structures used in production and operating under heavy loads.

The following products are widely used:

• rolls for cold rolling of alloys;
• disks and loaded parts;
• brackets;
• claw couplings;
• hardware;
• solid rolled rings;
• fittings for pipelines;
• products for the aircraft industry operating at +500 degrees.

Specifications

The high mechanical properties of 40ХН2МА are due to:

The cost of steel is at least 50 rubles/kg. The final price depends on delivery conditions, release form and volume.

Assortment

Products made from this alloy include:

• gears;
• bolts with a high class of responsibility;
• connecting rod shafts and covers for them;
• valves;
• crankshafts.

Production is carried out in accordance with the requirements of regulatory documents. Manufacturing involves performing a large number of technological processes, one of which is mechanical processing. It is designed to increase mechanical strength and the required appearance. In our company you can choose any type of rental.
