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 - steel quality very high.

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 under impact loads. The material can be used down to a temperature of -120 °C. It has good quenching and is prone to hydrogen embrittlement. This material is in great demand in general mechanical engineering. From the material 12h2n4a are made:

  • gears and transmission shafts;
  • piston and connecting rods;
  • pinion shafts and cardan shafts;
  • Bevel gears and ring gears.
