Chemical composition

The above structural steels are characterized by high percentage of chromium and nickel (see table). Steel 18Х2Н4ВА, in addition, has a composition of tungsten. Its chemical composition meets the requirements of GOST 4543:

Component C Si Mn Cr W Ni Cu
Percent in steel 0,14...0,20 0,17...0,37 0,25...0,55 1,35...1,65 0,8...1.2 4.0...4,4 Not more than 0.30

As non-metallic impurities in the steel 18Х2Н4ВА sulfur and phosphorus (amount of each element must not exceed 0,025%).

Close foreign analogues of steel 18Х2Н4ВА are not known. The 18CrNiMo7-6 (1.6587) and 17CrNiMo6 steels are considered to be the closest ones according to their chemical composition. These steels are produced in Europe according to EN 10204 standards. Specifically, 18CrNiMo7-6 has the following composition:

Component C Si Mo Ni AL Cr Cu
Percent in steel 0,12...0,18 0,15...0,40 0,25...0,35 1,40...1,70 1.40 1.70 No higher than 0.02 1,50...1,80 1,50 1,80 Not higher than 0,30

The percentage of sulfur and phosphorus in European counterparts cannot exceed 0.035%.

You may purchase 18Cr2H4VA, 18CrNiMo7-6, 17CrNiMo6 alloyed structural steel strip and plate using the offer of Evek GmbH. The price is from the manufacturer. Supplier guarantees the fulfillment of customer requirements on the assortment of sheet products, as well as on the terms of its delivery to the desired address.

Properties and application

Alloy steels 18Cr2H4VA, 18CrNiMo7-6, 17CrNiMo6 can be cemented, enhanced and hardened, followed by tempering. The final physical and mechanical parameters of these steels are as follows:

  • Tensile strength - 1050 MPa;
  • Ultimate ductility - 800 MPa;
  • Relative elongation - 12%;
  • Relative narrowing of the cross section - 50%;
  • Hardness after annealing - not more than 270 НВ;
  • Toughness - 780...1175 kJ/m2 (lower values correspond to rolled products with greater thickness).

After heat treatment, rolled sheets of these steels are used for stamping products, the operation of which is associated with higher requirements for strength, wear resistance and fatigue strength. Resistance is maintained up to temperatures of 420...4500 С. The weldability of steels is limited.

Buy at producer price rolled sheets of structural alloy steels grades 18Х2Н4ВА, 18CrNiMo7-6 and 17CrNiMo6 offers the company Evek GmbH. The supplier ensures compliance with the size and thickness of the sheet/strip, as well as their delivery to any point set by the customer.
