What is the common cold working die steel
The most commonly used cold working die steel is—— Cr12 cold working die steel 。 This kind of die steel is a kind of ledeburite steel with high carbon and high chromium content, which has good wear resistance and hardenability. However, because the carbon content of Cr12 Steel is as high as 2.3%, its impact toughness is relatively poor, it can not bear relatively large impact load, and it is easy to become brittle and crack, and the eutectic carbide formed will be uneven.
Cr12 cold working die steel It is especially suitable for cold heading dies of standard parts and steel balls, punches and punches for automobile spring plates; heavy blanking dies, cold extrusion dies, deep drawing dies, thread rolling dies, scissors pieces, cold upsetting dies, and clay moulds; it can be used for drawing dies and punching dies with high wear resistance and simple shapes, blanking dies, punches, thread rolling plates and ejector rods of stamping dies under small dynamic loads; 5. Sheet stamping dies and hand decorations It can be applied to large insert mould and punching thickness, steel plate large stamping die and shearing blanking die, paper cutter, clay mold and roll, etc 。
