Skd1 D3 Cold Work Tool Steel Flat & Blocks

D3 is an oil hardening, high Carbon Chromium type tool steel with very highwear resistance. It hardens with a very slight change in size. The alloypossesses very high compressive strength and is deep hardening.D3 is used intooling applications requiring a high degree of accuracy in hardening, such asdraw dies, forming rolls, powder metal tooling and blanking and forming dies.The machinability rating of D3 is roughly 25% that of free machining carbonsteel 1018.. Due to its abrasion resistant nature, machining in the hardenedcondition should be limited to finish grinding.
