X38CrMoV5-3

Delivery Method : Normalized, annealed 180-230HB

Uses : It is a hot work tool steel that can maintain its hardness at high temperature and has high toughness and thermal conductivity. It is widely used in molds, hot punching punches, hot cutting blades, metal injection and extrusion dies, where non-ferrous metals that are desired to be longer lasting are forged. It has high abrasion resistance. It is suitable for surface hardening with nitration process.
