Supplier guarantees the compliance with the assortment of profiles supplied, provides prompt delivery of products to the location specified by the customer.

Chemical composition

Steel 40 G according to GOST 4543 norms belongs to the group of alloyed structural manganese steels of domestic production. The composition of the steel includes:

  • Carbon - 0,37...0,45%;
  • Silicon - 0,17...0,37%;
  • Manganese - 0.70...1.00%.

There are also non-metallic impurities - sulfur and phosphorus. Their content for each of the elements may not be higher than 0,035%.

As for foreign counterparts of the steel under consideration, the steel grades 40Mn4 and AISI 1035 are considered to be the closest. AISI 1035 steel is produced in accordance with US ASTM A569 and ASTM A36 standards, and 40Mn4 steel is produced in accordance with EN 10083 and DIN 17200 standards. Chemical composition of analogues is given below:

  • Carbon - up to 0.40%;
  • Silicon - up to 0.38%;
  • Manganese - up to 0, 95%.

Company Evek GmbH offers to buy at a price from the manufacturer bulk (bars, rounds) and rolled tubes of constructional medium carbon steel grades 40G, 40Mn4, AISI 1035, which have high manganese content. The supplier guarantees strict adherence to the product mix and provides prompt delivery to the customer.

Properties and application

The steel of the mentioned grades is considered to be the basic one in production of high-strength parts for the handling equipment (gear shafts, gears, clutches, heavy-duty pipelines and etc). Steel is well amenable to plastic deformation in the hot state, so as the initial blanks are often used as forgings. Mechanical machinability of steels is moderate, it is desirable to use carbide metal-cutting tools. Steel is well amenable to all types of hardening heat treatment.

Physical and mechanical properties of steel grades 40G, 40Mn4, AISI 1035 after quenching and tempering are:

  • Tensile strength, MPa - 600;
  • Ultimate ductility, MPa - 360;
  • Relative elongation, % - 17;
  • Relative narrowing of the cross section, % - 45;
  • Impact toughness, kJ/m2 - 600.

Buy rounds, bars and tubes of manganese structural steel grades 40 G, 40Mn4, AISI 1035 offers the company Evek GmbH. All products are sold at a price from the manufacturer. Supplier ensures compliance with the range of supply of rolled products, its timely delivery to the address set by the customer is guaranteed.
