Evek GmbH offers to buy rolled sheets - sheets, strips and wires, which are made of 20XM, 24CrMo5, 1.7258, 20 hm alloy steels. The supplier sells the rolled steel at a favorable price from the manufacturer, provides timely delivery of products to the address specified by the customer.

Chemical properties

Structural steel grade 20XM, containing a high percentage of chromium and molybdenum, in the CIS countries is produced according to the technical standards of GOST 4543. The composition of steel is as follows:

Component C Si Mn Cr Mo
Percentage content in steel 0,15...0,25 0,17...0,37 0,40...0,70 0,80...1,10 0,15...0,25

GOST limits the maximum percentage of non-metallic impurities - sulfur and phosphorus: it can not exceed 0,025%.

There are a number of foreign equivalents of 20CrM steel. In Europe they are 24CrMo5 (1.7258) and 20 HM. The latter is produced in Poland, and by its composition and properties it does not practically differ from 20CrMo steel. 24CrMo5 (1.7258) steels are cast according to European standards EN 10028-2 and DIN 17755. The steels are characterized by the following composition:

Component C Si Mn Cr Mo Ni
Percentage content in steel 0,20...0,28 Not more than 0.40 0,50...0,80 0,90...1,20 0,20...0,35 0.60 max

Limitation of nonmetallic impurities - sulfur and phosphorus is 0,035% for each of the elements.

Buy rolled steel sheets - sheets, strips and wires made from structural steel grades 20HM, 24CrMo5, 1.7258, 20 hm with high chromium and molybdenum content offers the company Evek GmbH. All products are sold at manufacturer's prices. Supplier guarantees strict adherence to the product range, as well as its timely delivery to the location specified by the customer.

Properties and application

Increased percentage of molybdenum and chromium gives 20XM, 24CrMo5, 1.7258, 20 hm steels enhanced heat resistance, which is maintained to operating temperatures of 380...4000 С. These steels are also characterized by increased ductility, machinability and weldability. Materials are successfully subjected to various types of heat treatment - hardening, annealing, tempering. Parts made of the steels under consideration are used in the manufacture of bodies of pressure vessels, as well as for the production of heat-resistant fasteners.

The main physical and mechanical parameters :

  • Tensile strength - 740 MPa;
  • Yield strength - 440 MPa;
  • Elongation-ratio - 14%;
  • Relative narrowing of the profile - 50%;
  • Impact toughness - 750 kJ/m2.
