FCS 1.2746 Tool Steel
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.
