Evek GmbH offers to buy bulk rolled products and forgings from chromium-nickel cemented steel grades 12XH3A, 14NiCr14, 12hn3a at producer price. The supplier guarantees the compliance with the range of purchased products, and its timely delivery to the address specified by the customer.
Chemical composition
12ХН3А steel is produced in CIS countries according to
| Element | Carbon | Silicon | Manganese | Chrome | Nickel |
|---|---|---|---|---|---|
| Content, % | 0,09...0,16 | 0,17...0,37 | 0,30...0,60 | 0,60...0,90 | 2,75...3,15 |
Steel is allowed to have up to 0.2% copper, and non-metallic impurities - sulfur and phosphorus, the maximum percentage of which can not exceed 0.025%.
Well-known foreign counterparts of this steel are steels 14NiCr14 and 12hn3a (the latter is produced in Poland, and its consumer characteristics comply with the norms of the national standard PNH 84035). Steel 14NiCr14 is produced according to the requirements of Euronorm ISO 683-11 and is characterized by the following composition:
| Element | Carbon | Silicon | Manganese | Chrome | Nickel |
|---|---|---|---|---|---|
| Content, % | 0,11...0,17 | 0,17...0,37 | 0,30...0,60 | 1,25...1,75 | 3,25...3,75 |
Traces of sulfur and phosphorus are acceptable (although not limited to).
Company Evek GmbH offers to buy a bar, a circle and forgings from cemented structural steel 12ХН3А, 14NiCr14, 12hn3a. Supplier guarantees the price from the manufacturer. Delivery of rolled products and forgings is made to the address indicated by the consumer.
Properties and application
Low-carbon steels of the considered grades belong to the group of cemented steels, which increase the performance indicators as a result of the saturation of the surface and depth layers of carbon and nitrogen. At elevated temperatures, they form strong carbides and nitrides in the microstructure.
After quenching with tempering the mechanical characteristics of steels correspond to the following values:
- Ultimate strength, MPa - 950;
- Ultimate ductility, MPa - 700;
- Relative elongation, % - 12;
- Relative contraction, % - 55;
- Impact toughness, kJ/m2 - 1100.
Steels of 12XHN3A, 14NiCr14, 12hn3a grades are well machinable in cold and hot states, welding should be carried out under a layer of flux. Typical products made from these steels are considered cemented parts of high strength and toughness.
The company Evek GmbH offers to buy bulk rolled products - rounds, bars - as well as forgings of chromium-nickel constructional steels 12ХН3А, 14NiCr14, 12hn3a. Supplier guarantees favorable price from the manufacturer. Product delivery to the address set by the customer is provided.
