Cold Work Mold Steel

Cold work mold steel refers to the mold steel used to deform or form metal in a cold state

Cold work mold steels are essentially high-carbon steels, which contain relatively low alloy additions of tungsten, manganese, chromium and molybdenum. These alloy additions increase hardness, permitting oil quenching with less distortion than with the W series. and their high carbon content produces adequate wear resistance for short-run applications. It is used for all types of blanking and forming molds, gauges, collets, etc.

The performance of cold work mold steel:

1. High wear resistance

2. High strength and toughness

3. Strong bite resistance

4. Heat-softening ability

Selection method

1. When selecting cold work mold steel, it is necessary to consider the processing method, stress state, material properties of the forming object, production quantity, plate thickness, etc. In addition, the size and dimensional accuracy of the mold are also factors that cannot be ignored.

2. Low-alloy tool steel (SKS) is used for small load or small batch production, cold work mold steel (SKD) is used for heavy load or mass production, and high-speed tool steel and powder high-speed tool steel are used for larger load.

3. Suitable for wear-resistant occasions are cold work mold steel, high-speed tool steel and high-alloy high-speed tool steel, suitable for impact-resistant occasions are 8Cr-2Mo series mold steel and matrix high-speed tool steel.
