Chemical composition
High-quality medium-carbon boiler steel grade 20K is produced in accordance with the technical requirements
| Component | Carbon | Silicon | Manganese | Nickel | Chrome | Copper | Arsenic |
|---|---|---|---|---|---|---|---|
| Percentage content in steel | 0,16...0,24 | 0,15...0,30 | 0,35...0,65 | Up to 0.30 | Up to 0.30 | Up to 0.30 | Up to 0.08 |
There are sulfur and phosphorus as metallurgical impurities in the composition of this steel, the percentage of which, according to current standards, may not exceed 0.03%.
The closest foreign equivalents of steel 20K are considered to be P265GH and st41K. They are produced in accordance with EN 10216 pipe rolling), and German DIN standards. The composition of both analogues are about the same, but it depends on the range of supply of rolled products:
| Component | Carbon | Silicon | Manganese | Nickel | Chrome | Copper | Vanadium |
|---|---|---|---|---|---|---|---|
| Percentage in steel | Not more than 0.20 | Not more than 0,1...0,2 | 0,70...1,40 | Up to 0.30 | Up to 0.30 | Up to 0.30 | Up to 0.02 |
Steel P265GH also contains niobium (up to 0,0012%), 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. Tubular and volumetric rolled steel is sold at manufacturer's price. Product delivery is provided to the address specified by the buyer.
Workability and application
The physical and mechanical characteristics of the materials in question are as follows:
- Tensile strength at break, MPa - 390...530;
- ultimate ductility in the cold state, MPa - 185 ... 265 (ductility increases with increasing cross-sectional dimensions);
- Relative elongation, % - 22;
- Relative contraction, % - 40;
- Impact toughness at room temperature, kJ/m2 - 27...40.
Steels are well amenable to pressure treatment in hot and cold state, can be subjected to various modes of heat treatment, are not prone to flaking and to tempering brittleness. They are used to produce spatial parts power equipment, stop valves for steam boilers, as well as similar products, the operating temperature which does not exceed 400 ... 4500 C..
