Such a steel has good toughness and high-temperature fatigue properties can withstand the temperature of fusion, have good long-term suitably cutting and polishing properties at high temperatures, also suitable for producing a high yield of plastic mold nitriding process can achieve good mold surface The structure of the hardened layer improves abrasion resistance and corrosion resistance of the extrusion die.

Uses : For manufacturing aluminum, magnesium, zinc alloy die-casting die, aluminum extrusion hot hammer or hot stamping work, hot work reamer, grooving knife, scissors and hot forging punch ... etc.
