The company Electrocentury-steel offers to buy at factory price bulk rolled and forgings of Nickel-chromium case hardening steel grades 12KHN3A, 14NiCr14, 12hn3a. The supplier guarantees compliance with the assortment of purchased products, and timely delivery to the address specified by the consumer.
12KHN3A steel produced in the CIS countries and Russia GOST 4543, and belongs to the group of low-carbon low-alloy steels with a high Nickel content. The chemical composition was the following:
|Content, %||0,09 0,16…||0,17…0,37||0,30…0,60||0,60…0,90||2,75 3,15…|
In the steel allowed the presence of copper in amounts up to 0.2% and non-metallic impurities — sulfur and phosphorus, the greatest percentage of which cannot exceed 0,025%.
Well-known foreign analogues of this steel are steel 14NiCr14 and 12hn3a (last produced in Poland, and its consumer characteristics meet the standards of the national standard PNH 84035). 14NiCr14 steel produced in accordance with the requirements of Euronorm ISO 683−11, and is characterized by the following composition:
|Content, %||0,11 0,17…||0,17…0,37||0,30…0,60||1,25 1,75…||3,25 3,75…|
Are allowed (though not limited to) traces of sulphur and phosphorus.
The company Electrocentury — steel offers to buy rod, scope and forging of case hardening structural steel 12KHN3A, 14NiCr14, 12hn3a. The vendor guarantees the price from the manufacturer. Delivery of rolled products and forgings is performed at the address indicated by the consumer.
Properties and applications
Low carbon steel grades under consideration belong to the group of case hardening steel, improving operational performance which is the result of the saturation of the surface and deep layers of carbon and nitrogen. At elevated temperatures they form a solid microstructure of carbides and nitrides.
After quenching with vacation mechanical characteristics of steels correspond to the following values:
- Tensile strength, MPa — 950;
- The plastic limit, MPa — 700;
- Elongation, % of 12;
- The relative narrowing, % — 55;
- Impact strength, kJ/m2 — 1100.
Steel grades 12KHN3A, 14NiCr14, 12hn3a have good workability in cold and hot conditions, welding must be performed under the flux layer. Typical products made of these steels are considered to be case hardening parts with high strength and toughness.
Buy bulk rolling — circle, bar and forgings of chrome-Nickel constructional steels 12KHN3A, 14NiCr14, 12hn3a, the company offers Electrocentury-steel. The supplier guarantees the best price from the manufacturer. Ensured product delivery at the address set by the client.
