12hn3a is a chromium-nickel alloy structural steel, also known as 12xh3a. Its material designation signifies:
- 12 – 0.12% carbon content
- H – about 1% chromium
- N3 – about 3% nickel
- A – exceptionally high steel quality
This steel grade offers high strength along with excellent plastic deformability. Thanks to its chromium and nickel content, 12xh3a features good impact resistance at low temperatures and excellent mechanical properties. It is highly hardenable but has limited weldability.
If you’re looking to purchase 12hn3a, Evek GmbH Online Shop provides a comprehensive selection of GOST steels to match your needs.
12xh3a round steel is commonly used for manufacturing highly stressed components that operate at low temperatures (down to -100°C) and require superior strength. Typical applications include:
