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.
Round bar 12hn3a is in great demand in the production of various highly stressed components that operate at low temperatures down to -100 °С and are subject to very high strength requirements. Material 12xh3a is used to manufacture:
- gears and shafts;
- worm gear;
- Axles;
- elastomer couplings;
- gudgeon pin.
The following properties distinguish 12hn3a:
- conditionally suitable for welding (manual arc welding, TIG welding);
- high strength;
- good plastic deformability;
- good impact resistance at low temperatures;
- high hardenability.
As a supplier for 12xh3a we deliver worldwide. Buy GOST steels at a good price from Evek GmbH. We are at your side and will be happy to help you with your concerns.
