12hn3a is a chromium-nickel alloy structural steel. The designation 12xh3a refers to:

• 12 – 0.12% carbon content;
• H – approximately 1% chromium;
• N3 – approximately 3% nickel;
• A – indicates very high steel quality.

This steel grade offers high strength and good plasticity. Thanks to its chromium and nickel content, 12xh3a maintains excellent impact resistance even at low temperatures and possesses strong mechanical properties. It features high hardenability, but its suitability for welding is limited.

If you are looking to buy 12hn3a, you are in the right place. The Evek GmbH Online Shop offers a broad selection of GOST steels, ensuring high product satisfaction.

12xh3a round steel is widely used in manufacturing highly stressed components that operate at low temperatures (down to -100°C) and require exceptional strength, including:
