12hn3a is an alloyed chromium-nickel structural steel. The designation 12xh3a indicates:

• 12 – 0.12% carbon content;
• H – about 1% chromium;
• N3 – about 3% nickel;
• А – very high steel quality.

This steel combines high strength with good plasticity. Due to its chromium and nickel content, 12xh3a offers reliable impact resistance at low temperatures and excellent mechanical properties. It also features high hardenability, though its weldability is limited.

If you are looking to purchase 12hn3a, our online shop has a wide selection of GOST steels. Evek GmbH ensures you will be satisfied with our products.
