Tool Steel

X40CrMoV5-1 steel, as a hot work die steel, is characterized by its excellent high-temperature performance combination, which combines high toughness and high-temperature strength, making it particularly suitable for repeated thermal cycling conditions such as die-casting molds; X40CrMoV5-1 steel undergoes electroslag remelting process to ensure material uniformity, and with optimized heat treatment process, it can achieve 48-52HRC hardness. X40CrMoV5-1 steel has excellent resistance to thermal fatigue, aluminum/copper alloy erosion, and extremely low heat treatment deformation rate. After surface nitriding treatment, the hardness can reach HV1000 or above, significantly extending the mold life.

1.2746 steel exhibits excellent versatility in both cold and hot working applications. As a high-quality tool steel, it performs well in cold working molds (stamping, stretching, cold heading) for automotive and electronic manufacturing due to its excellent wear resistance and deformation resistance under high loads. Meanwhile, the excellent high-temperature stability and thermal fatigue resistance of 1.2746 steel make it an ideal choice for hot forging and die-casting molds in the aerospace and home appliance industries, significantly extending the service life of the molds while maintaining accuracy under extreme conditions (up to 400 ° C). This dual capability stems from its optimized alloy composition, which has balanced nickel chromium molybdenum vanadium elements.
