Evek GmbH offers to buy pipes, rods, circles made of medium-carbon alloy steel 38Cr2H2MA, 34CrNiMo6, 40NiCrMo7, 36hnm at producer price. The supplier guarantees the performance of the assortment range of supply, as well as the prompt transportation of products to the customer.

Chemical composition

Medium-carbon structural steel 38Х2Н2МА of improved quality, alloyed with chromium, nickel and molybdenum, in the CIS countries is produced in accordance with the requirements of GOST 4543. The steel composition includes:

Element Carbon Silicon Manganese Chrome Nickel Molybdenum Copper
Presence in steel, % 0,33...0,40 0,17...0,37 0,25...0,50 1,30...1,70 1,30...1,70 0,20...0,30 Up to 0.30

There are several known analogues of this steel. Practically similar chemistry is produced in Poland as steel 36hnm. The other analogues are 34CrNiMo6 (1.6582) and 40NiCrMo7 alloy steels, melted by European steel makers in accordance with EN 10083-3. The composition of these steels differs from 38Cr2H2MA as is shown in the table below (data for 34CrNiMo6):

Element Carbon Carbon, silicon Carbon, silicon Chromium Nickel Molybdenum
Presence in steel, % 0,30...0,38 Up to 0.35 0,50...0,80 1,30...1,70 1,30...1,70 0,15...0,30

Company Evek GmbH offers to buy bulk rolled products - bars, tubes, rounds, made from alloy construction steel grades 38Х2Н2МА, 34CrNiMo6, 40NiCrMo7, 36hnm. Cost-effective price from the manufacturer. Supplier guarantees the performance of the product range, as well as ensures its timely transportation to the location specified by the customer.

Properties and application

The steels under consideration are designed for producing forgings and finished parts with high temperature resistance. The steel is well heat treated, the main type of heat treatment is considered to be refinement. Improved shafts, axles, gears, and other similar products can have considerable size and complex configuration. The weldability of steel is limited.

The main mechanical values of steels of this type that have been quenched and tempered are:

  • Tensile strength, MPa - 850...900;
  • yield strength, MPa - 735...785;
  • Relative elongation, % - 11...13;
  • Relative narrowing of cross-section, % - 39...40;
  • Impact viscosity, kJ/m2 - 55...60;
  • Brinell hardness, NV - 270...320.

Buy tube, rounds, bars of medium-carbon alloy steels 38Ch2H2MA, 34CrNiMo6, 40NiCrMo7, 36hnm at producer price offers the company Evek GmbH. The supplier guarantees the performance of the assortment minimum supply, provides prompt transportation of rolled products to the address specified by the customer.
