12hn3a is a chromium-nickel alloyed steel classified as structural steel. The 12xh3a designation stands for:
- 12 – 0.12% carbon content
- H – approximately 1% chromium
- N3 – around 3% nickel
- A – very high steel quality
This material offers high strength and good plastic deformability. Thanks to its chromium and nickel content, 12xh3a maintains excellent impact resistance even at low temperatures and provides strong mechanical properties. The steel is highly hardenable and has limited weldability.
If you're looking to purchase 12hn3a, Evek GmbH Online Shop is your reliable source, offering a wide selection of GOST steels. We guarantee satisfaction with our products.
