In the mold steel, high speed steel and high carbon present high chromium steel wear resistance is highest. But in the case of steel, the presence of severe carbide segregation or large carbide particles, these carbides easy to peel off and cause abrasive wear, more so wear light-load speed up the cold mold (sheet blanking, drawing, bending etc.) of the impact load is not primarily static wear. Under static wear conditions, the carbon content of the steel mold more, higher wear resistance. In impact wear conditions (such as cold heading, cold extrusion, forging, etc.), excessive mold steel carbide help to improve the wear resistance SLD hardness, but because of the impact of abrasive wear will reduce its wear resistance. Studies have shown that, under the impact of abrasive wear conditions, the carbon content of the steel mold with 6 00 / a ceiling, above which the wear process dramatically accelerated. Cold shovel mold work under impact loading conditions SLD, such as excessive carbide steel mold, easy to wear due to the impact of the emergence of flaking. These hard particles flaking, will become abrasive and accelerate the wear rate. Hot surfaces of the mold cavity, reducing wear due to high temperature softening leaving. In addition, iron oxide abrasive skin also play a role, while the SLD price, as well as high-temperature oxidation corrosion. Therefore, the wear process is extremely complex hot die wear much faster than the cold mold.
