Evek GmbH offers to buy sheets and strips made of structural alloy steels 20X, 20Cr4, 20h. The supplier provides a favorable price from the manufacturer. Prompt delivery of products to the address specified by the customer is guaranteed.

Chemical Composition

Low-carbon alloyed steel 20Х, which is produced in CIS countries in accordance with GOST 4543 specifications, has the following composition:

Component C Si Mn Cr Ni Cu
Percentage content in steel 0,17...0,23 0,17...0,37 0,50...0,80 0,70...1,00 0.25 maximum Not more than 0.20

Among the non-metallic impurities in the steel allowed presence of phosphorus and sulfur, the percentage content of which can not be more than 0.035%.

Steel 20X has a number of foreign analogues. For example, in Poland steel with similar composition is produced under mark 20h, and in EU countries under mark 20Cr4. Technical requirements to the above-mentioned steels correspond to AISI 5120 and European standards DIN 17210. The chemical composition of analogues is almost identical to the brand 20X.

Company Evek GmbH offers consumers to buy rolled sheets - sheets and strips made of structural steel grades 20X, 20Cr4 and 20h, alloyed with chromium. Products are sold at manufacturer's economically attractive prices. Supplier provides the required assortment minimum of the assortment and its prompt delivery of products to the address specified by the customer.

Properties and application

Chromium-alloyed structural steel of 20X, 20Cr4 and 20h grades may undergo various heat treatment operations - annealing, tempering and quenching. After quenching, the physical and mechanical properties of the steels in question are:

  • Tensile strength - 800 MPa;
  • yield strength - 650 MPa;
  • Relative elongation - 11%;
  • Relative narrowing of the cross section - not less than 40%;
  • Brinell hardness - not more than 187 NV.

In most cases, cementation is applied to billets and parts of these steels. Carburizing. Following carburizing, the rolled sheets are used for critical applications that require high contact stresses. Sheet and strip of these steels are well amenable to the separation and cold forming operations (with the exception of deep drawing), processed on the metal cutting equipment. The weldability of cemented products is limited.

Buy rolled sheets of structural chrome-containing steel 20X, 20Cr4 and 20h.- circle, bar, offers the company Evek GmbH. Prices are from the manufacturer. Supplier provides the necessary assortment minimum of delivery, as well as prompt transportation of products to the point set by the customer.
