Buy a variety of bulk rental — round, wire or tube — stainless steel brand 20KH17N2 (ЭИ407) at cost-effective price the manufacturer offers KMZ. The company ensures the timely delivery of the products to any address set by the user.

The composition and application of

Corrosion-resistant high-strength steel 20KH17N2 (ЭИ407), under the previous designation — 2Х17Н2 is a stainless steel martensitic class for General use, which is used for the manufacture of parts operating under conditions of high mechanical and frictional loads. Steel responds well to heat treatment, has excellent corrosion resistance, high strength, including tension loads. Steel satisfactorily amenable to plastic deformation due to high values of yield strength,

but suitable for formoizmeneniya operations stamping.

Laplacebeltrami steels is usually carried out using methods that allow to harden the product. Its corrosion resistance steel 20KH17N2 (ЭИ407) is inferior to austenitic stainless steels. At low temperatures steel loses its strength properties.

The chemical composition of steel (data in percent) governed by the requirements of GOST 5632−80:

C Si Mn Ni S P Cr
0.17 0.25… Not more than 0.8 Not more than 0.8 1.5… 2.5 Not more than 0.025 Not more than 0.035 16… 18

CMH implements at reasonable prices from the manufacturer a diverse range of bulk and profile rolling — circle, wire, pipe, stainless steel brand 20KH17N2 (ЭИ407). Supplier ensures prompt delivery of products at any address specified by the customer.


Physical characteristics of steel 20KH17N2 (ЭИ407):

  • Density, kg/m3 — 7800;
  • Coefficient of thermal expansion in the temperature range 20…3000 C, µm/deg — 12,1;
  • Coefficient of thermal conductivity for temperatures of 20 to 1000 C, W/mgrad — 20,2;
  • Specific heat, j/kgrad — 460;
  • The modulus of elasticity, GPA — 200.

Mechanical properties after annealing:

  • The limit of temporary resistance, MPa — 860;
  • Yield strength, MPa — 655;
  • Relative tensile elongation, % — 20;
  • Brinell hardness number, HB — 285.

Technological parameters:

Weldability of steel 20KH17N2 (ЭИ407) is limited because of the danger of brittle cracking. Before welding it is recommended to heat the materials up to 200…300 °C, and after welding, to carry out the heat treatment at 650 °C. machining in the annealed state is easy.
