P20 + Ni (DIN 1.2738 )

It is a steel developed in Europe and is a variant of AISI P20 steel, to which nickel (Ni) has been added to improve hardenability, thereby developing:

  • A smaller variation in hardness from the surface to the center, an appreciable characteristic in large dimensions.
  • More uniform mechanical properties throughout its volume.
  • Good machining characteristics and better polishability.
  • Ease of applications for gravure.

It can be surface hardened via nitriding processes.
