Chemical composition
High-quality medium-carbon boiler steel stamps 20K is made in accordance with the technical requirements of GOST 5520. It has the following chemical composition:
| Component | Carbon | Silicon | Manganese | Nickel | Chrome | Copper | Arsenic |
|---|---|---|---|---|---|---|---|
| The percentage of steel | 0,16 0,24… | 0,15 0,30… | 0,35…0,65 | To 0.30 | To 0.30 | To 0.30 | To 0.08 |
As a metallurgical impurities in the composition of the steel are sulfur and phosphorus, the percentage of which according to current regulations may not exceed 0,03%.
The closest foreign analogues of steel 20K and steel are considered Р265GH st41K. They are produced according to the standards EN 10216 pipe rental) and German DIN standards. The composition of the two analogues are about the same, but it depends on the product mix and the supply of hire:
| Component | Carbon | Silicon | Manganese | Nickel | Chrome | Copper | Vanadium |
|---|---|---|---|---|---|---|---|
| The percentage of steel | 0.20 | Not more than 0,1…0,2 | 0,70 1,40… | To 0.30 | To 0.30 | To 0.30 | To 0.02 |

Workability and application
Physico-mechanical characteristics of materials are:
- Tensile strength at break, MPa — 390…530;
- The limit of the plasticity in cold condition, MPa — 185…265 (larger cross-section ductility increases);
- Elongation % — 22;
- The relative narrowing, % — 40;
- Impact strength at room temperature, kJ/m2 — 27…40.
Steel respond well to pressure treatment hot and cold condition can be subjected to various heat treatment regimes, do not tend to flokirovanie and brittleness. Of them produce spatial details of energy power equipment, isolation valves to steam boilers and the like, the operating temperature of which does not exceed 400…4500 C.
