Chemical composition of steels

Rolled steel of boiler grade 20K is produced in accordance with technical requirements of GOST 5520. The chemical composition of steel meets the following indicators:

Element C Si Mn Ni Cr Cu As
Content, % 0,16...0,24 0,15...0,30 0,35...0,65 Not more than 0.30 Not more than 0.30 .30 not more than 0.30 Not more than 0.08

In addition, in the composition of steel 20K as metallurgical impurities present phosphorus and sulfur. Their percentage according to the standard should not exceed 0.03%.

The closest foreign analogues of this steel should be steel P265GH and steel st41K, melting of which is conducted according to norms EN 10217 (wire), and German DIN standards (sheet rolling). The composition of the analogues does not differ much from each other and corresponds to the following data (given in relation to the rolled plate):

Element C Si Mn Ni Cr Cu V
Content, % Not more than 0.20 Not above 0,1...0,2 0,70...1,40 0.40 0.70 1.40 No higher than 0.30 0,30 not higher than 0,30 .30 not higher than 0,30 Not higher than 0.02

Besides that, steel P265GH may also contain niobium (up to 0.012%), aluminum (up to 0.03%) and titanium (up to 0.04%).

Company Evek GmbH offers to buy at favorable price from the manufacturer quality structural steel grades 20K, P265GH and st41K. Rolled sheets and wire sold at an economically attractive price from the manufacturer. Product delivery is provided to the address specified by the customer.

Workability and application

The performance indicators of the steels are as follows:

  • Tensile strength - 390...530 MPa;
  • Limit of plasticity - 185...265 MPa (for thick plates plasticity is higher);
  • Relative elongation - 22%;
  • Relative contraction - 40%;
  • Impact toughness - 27...40 kJ/m2 (lower values are for plates and strips).

Steels are well processed by pressure, subjected to heat treatment under different modes, are not prone to the formation of flokens and brittleness after tempering. They are used for flat sheet structures of large boilers and similar products operating at the temperatures not higher than 400-4500 C.

Evek GmbH offers to buy sheets and wires of structural boiler steels 20K, P265GH and st41K at manufacturer's economical prices. The supplier ensures compliance with the assortment sizes, as well as delivery of purchased products to the address set by the customer.
