12hn3a is a chromium-nickel alloyed steel classified as structural steel. Its designation stands for:

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

This steel combines high strength with good plastic deformability, thanks to its chromium and nickel content, offering good impact resistance even at low temperatures. 12xh3a is highly hardenable but has limited weldability.

If you’re looking to purchase 12hn3a, our online shop provides a broad selection of GOST steels. We ensure you’ll be satisfied with our products.

12xh3a round steel is widely used for manufacturing heavily loaded components operating at low temperatures down to -100 °C, where high strength is required. Typical applications include:
