Evek GmbH sells pipes, rounds, bars, which are made of structural alloy steels 30XH2MA, 30CrNiMo8 (1.6580), AISI 4340. There is a cost-effective price from the manufacturer of rolled steel. Supplier ensures compliance with the range of supply, and guarantees prompt delivery to the customer.

Chemical composition

In the CIS countries alloyed steel grade 30KhN2MA is produced according to the technical requirements of GOST 4543, and is characterized by the following chemical composition:

Element Carbon Silicon Manganese Chrome Nickel Molybdenum
Percentage content in steel 0,27…0,34 0,17…0,37 0,30…0,60 0,60…0,90 1,25…1,65 0,20…0,30

The amount of nonmetallic impurities — phosphorus and sulfur — may not exceed 0,025%.

The closest foreign equivalents of 30XH2MA steel are 30CrNiMo8 (1.6580), which is produced in Europe according to EN10269 (round, bar) and EN 10297−1 (pipes), and also steel AISI 4340 melted in the USA according to ASTM A366.

Their composition slightly differs from that given above. For example, 30CrNiMo8 steel contains the following elements:

Element Carbon Silicon Manganese Chrome Nickel Molybdenum
Percentage content in steel 0,26…0,34 Up to 0.40 0,50…0,80 1,80…2,20 1,80…2,20 0,30…0,50

Buy rounds, bars, tubes, which are made from structural alloy steel grades 30XH2MA, 30CrNiMo8 (1.6580), AISI 4340, offers the company Evek GmbH. The price is from the manufacturer. Supplier provides strict adherence to the range of supply, guarantees the timely transportation of products to the customer.

Properties and application

Medium-carbon structural alloy steel of the considered grades is characterized by good machining ability. The steels are used for parts whose operating conditions require high strength and wear resistance with sufficient toughness of the core. Such parts include critical gears, gears, shafts, etc.

Mechanical characteristics of volumetric rolled steels are as follows:

  • ultimate strength, MPa — 1250… 1450;
  • ultimate ductility, MPa — 750…900;
  • Relative elongation, %, not less than 11…12;
  • Relative narrowing, % — 45…50;
  • Brinell hardness, HB — not more than 248.

Company Evek GmbH offers to buy at producer price rounds, bars and tubes of structural alloy steels 30XH2MA, 30CrNiMo8 (1.6580), AISI 4340. Supplier ensures compliance with the range of supply, as well as guarantees the timely transportation of products to the consumer.
