12hn3a is a chromium-nickel alloyed structural steel. The designation 12xh3a stands for:
- 12 - 0.12% carbon content
- H - about 1% chromium
- N3 - about 3% nickel
- A - very high steel quality
This steel offers excellent strength and good plastic deformability. Thanks to its chromium and nickel content, 12xh3a also features good impact resistance at low temperatures and outstanding mechanical properties. The material is highly hardenable but has limited weldability.
