Precipitation hardening nickel martensitic (maraging) steel, material number 1.2709, which offers a good combination of strength and toughness. Can be printed very easily without additional heating of the building platform 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.
Particle size distribution 15 – 45 µm:
D10[µm] 18 – 24
