Tool Steel

CXPlus

Cxplus is a corrosion-resistant, maraging (martensitic aging) steel developed by powder manufacturer m4p. It combines the excellent processability and low cracking tendency of maraging tool steels with a level of corrosion resistance closer to stainless steel. Through aging, the material reaches very high hardness while remaining tough, making it a high-performance choice for demanding tooling and industrial applications.

Properties

  • Very high strength and hardness
  • Good corrosion resistance
