20h2n4a is an alloyed chrome-nickel steel. This type of steel belongs to the category of structural steels. The material designation 12xh3a means:

  • 20-0.20% carbon content;
  • H2 - approx. 2% chromium;
  • N4 - about 4% nickel;
  • А - very high steel quality.

The material has excellent plastic deformability in combination with high core toughness. The high surface hardness allows it to be used with high impact loads and at low temperatures. The material is poorly suitable for welding. Preheating to 200-300 ° C is required to achieve optimal welding results. After welding, heat treatment by annealing is necessary.
