The chemical composition of the steels
Hire quality steel boiler class stamps 20K produced in accordance with technical requirements GOST 5520. The chemical composition of steel meets the following criteria:
|Content, %||0,16 0,24…||0,15 0,30…||0,35…0,65||Not more than 0.30||Not more than 0.30||Not more than 0.30||Not more than 0.08|
In addition, the composition of the steel 20K metallurgical impurities are phosphorus and sulfur. Percentage standard should not be more than 0.03%.
Of the closest foreign analogues of this steel should be noted Р265GH steel and steel st41K, smelting which is carried out according to standards EN 10217 (wire), German DIN standards (sheet metal).

Workability and application
The performance of the following steels:
- Limit strength — 390…530 MPa;
- The plastic limit is 185…265 MPa (HRP plasticity above);
- Elongation — 22%;
- The relative narrowing — 40%;
- Toughness — 27…40 kJ/m2 (smaller values for sheet and strip).
Steel is well-processed pressure, subjected to heat treatment at different modes, not prone to placenow and brittleness after a holiday. Of them produce a flat sheet design of large boilers, and similar products, operating at temperatures not exceeding 400…4500 C.
