Evek GmbH offers to buy at the manufacturer's price pipes, rounds, bars, which are made of medium-carbon structural steel grades 45G2, 35S20, AISI 1144 with increased manganese content. The supplier guarantees the assortment of rolled product supplies, as well as its timely delivery to the customer.

Chemical composition

Structural medium-carbon steel 45G2 grade in CIS countries

CIS is produced in accordance with the specifications of GOST 4543. The steel contains:

  • 0.41...0.49% carbon;
  • 0.17...0.37% silicon;
  • 1.40...1.80% manganese.

In addition, the steel has metallurgical impurities - sulfur and phosphorus, the percentage content of which cannot be more than 0.04%.

The most famous foreign analogues of steel 45G2 are steel 35S20 (produced by European metallurgical companies) and steel AISI 1144 (corresponding to the North American standard ASME1045). In their composition they practically do not differ from steel 45G2 (traces of chromium, nickel, copper and aluminum are allowed).

Company Evek GmbH offers to buy bulk rolled products - rounds, bars and tubes of medium carbon steel 45G2, 35S20, AISI 1144, containing high manganese content. The price is from the manufacturer. The supplier guarantees the timely delivery of rolled products to the address specified by the customer, and strict adherence to the range of products supplied.

Properties and application

Medium carbon steel with high manganese content is used for high-strength pipes operating under increased working pressures, as well as critical parts of mechanical gears - pulleys, flywheels, gears that constantly transmit high torque. Cold workability is limited, weldability is reduced.

Physical and mechanical properties of 45G2, 35S20, AISI 1144 steels are as follows:

  • Tensile strength - 745 MPa;
  • Ultimate ductility - 635 MPa;
  • Modulus of elasticity - 190 GPa;
  • Relative elongation - 10%;
  • Relative contraction - 30%;
  • Brinell hardness - not higher than 228 NV.
