12h2n4a is an alloyed chromium-nickel structural steel. The material designation 12h2n4a means:
- 12 - 0.12% carbon content;
- H2 - 2% chromium;
- N4 - 4% nickel;
- А - very high steel quality.
The grade has very good toughness and high core strength. It also has great wear resistance and good surface hardness. The material is characterized by poor machinability, due to the addition of nickel. It has limited weldability and can only be welded with appropriate preheating and post-annealing.
If you are looking for a reliable 12h2n4a supplier, you have come to the right place. Evek GmbH online shop offers a variety of GOST steels and works for you around the clock.
12h2n4a is mainly used for highly stressed components subject to shock loads. The material can be used up to a temperature of -120 ° C.
