    Product Description

    Percipitation hardening nickel martensitic (marging) steel, material number 1.20709, which offers a good combination of strength and toughness. Can be printed very easily without additional heating of the building plattform or chamber. The achievable hardness of 55 HRC makes this material a universal solution for tool steel applications in which conformal cooling is required, such as die casting applications.
