What is the cold work die steel DC53?

DC53 steel is a high-performance cold work die steel that steel mills have carried out the latest improvements and upgrades to the existing JIS standard SKD11 die steel in Japan. It overcomes the weakness of SKD11 high temperature tempering hardness and toughness, and will completely replace SKD11 in the field of general and precision molds.

The heat treatment hardness of DC53 die steel is higher than SKD11, and the high temperature is 520-530℃. After tempering, it can reach high hardness of 62-63HRC. In terms of strength and wear resistance, Steel DC53 surpasses SKD11 die steel. The toughness of DC53 material is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. The tools made of DC53 rarely show cracks and cracks, which greatly improves the service life.

DC53 cold work die steel is widely used in punching dies, cold forming dies, cold drawing dies; forming rolls, punches; precision stamping dies; wire cutting precision blanking dies and stamping dies for various purposes; difficult-to-process materials Tools for plastic deformation; dies for cold forging, deep drawing and thread rolling; high-speed blanking punches, punches for stainless steel plates.
