Evek GmbH offers to buy pipes, rounds, bars, which are made of manganese-alloyed structural steel grades 20G, 20Mn5 and 1.1133. The price is from the manufacturer. The supplier guarantees compliance with the range of supply, as well as the timely transportation of rolled products to the address specified by the customer.

Chemical composition

In the CIS countries the production of 20 G steel is carried out according to the technical requirements of GOST 4543. The composition of the steel consists of:

  • Carbon - 0.17...0.24%;
  • Silicon - 0.17...0.37%;
  • Manganese - 0,70 ... 1,00%.

As metallurgical impurities are allowed to have traces of copper and nickel, as well as non-metallic elements - sulfur and phosphorus (percentage of the latter can not be higher than 0,025%).

Foreign counterparts of steel 20 G are considered to be grades 20Mn5 and 1.1133. They are produced in accordance with European standards EN 20269 and EN 10250. The chemical composition of European counterparts is as follows:

Element Carbon Silicon Manganese Nickel, Chromium Molybdenum Aluminum
Presence in steel, % 0,17...0,23 Not more than 0.40 1,0...1,5 Not more than 0.40 Not more than 0.10 Not more than 0.02

The presence of phosphorus and sulfur in the percentage amounts not exceeding 0.035% for each element is allowed. In addition, these European standards provide for traces of niobium and titanium. The total percentage of nickel, chromium and molybdenum may not exceed 0.63%.

Evek GmbH offers to buy bars, tubes and circles of manganese structural steel grades 20G, 20Mn5 and 1.1133 at producer price. The supplier guarantees adherence to the range of metal supply, guarantees quality and timely transport of products to the customer.

Properties and application

Steels of the above grades are used in the manufacture of critical parts of mechanisms - beams and tie rods of crane equipment, small gears and cogwheels, rings and hubs of brake drums of vehicles. Steels have good weldability, as well as good machinability by cutting and pressure.

The mechanical properties of 20G, 20Mn5 and 1.1133 steels after heat treatment are as follows:

  • Tensile strength, MPa - 460;
  • yield strength, MPa - 280;
  • Relative elongation, % - 24;
  • Relative narrowing, % - 50;
