Turned Surface Round Bar DC53 Cold Work Tool Steel
Turned surface cold work tool steel round bar DC53 steel in annealing codiction
Description:
DC53 steel is a new cold die steel modified from SKD11/D2. Its technical specification is set out in The Japanese Industrial Standard (JIS) G4404.It overcomes the weakness of SKD11/D2 in high temperature tempering hardness and toughness, and will replace SKD11 completely in general and precision mold field.Its toughness is twice that of SKD11, and the toughness of DC53 is more prominent in cold mold steel. The tools made with DC53 seldom appear cracks and cracks, which greatly improves the service life.
Application:
Precision punching die: precision punching die for linear cutting and various purposes
Tools for plastic deformation of refractory materials
Die for cold forging, deep drawing and wire drawing
1. Punching mold, cold working molding mold, cold drawing mold
