12hn3a is an alloyed chromium-nickel steel that is classified as structural steel. The material designation 12xh3a means:

• 12 - 0.12% carbon content;
• H - about 1% chromium;
• N3 - about 3% nickel;
• А - steel quality very high.

This material has high strength combined with good plastic deformability. 12xh3a has good impact strength at low temperatures and good mechanical properties due to chromium and nickel content. The material has a high hardenability and is only conditionally suitable for welding.

If you're looking to buy 12hn3a, you've come to the right place. Evek GmbH online shop offers a wide range of GOST steels. You will remain satisfied with our products.
