1.Application
DC53 steel is a new general purpose cold work die and mold steel whose strength and toughness approach those of high-speed steels.
DC53 steel, is an improvement over alloy tool steel D2.
It has the following unique characteristics:
• Higher hardness (62-64 HRc) than D2 after heat treatment.
• Twice the toughness of D2 with superior wear resistance.
• Substantially higher fatigue strength compared to D2.
• Smaller primary carbides than D2 protect the die from chipping and cracking.
• Secondary refining process (DLF) reduces impurities.
• Machines and grinds up to 40% faster than D2.
• Less residual stress after wire EDMing.
2. Melting process
EAF+LF+VD
