DC-53 General Purpose Die and Mold Steel
DC-53 is a general purpose, cold work die and mold steel that also provides excellent strength and toughness that approaches those of high-speed steels. DC53, is an improvement over alloy tool steel D-2. It eliminates the disadvantages of insufficient hardness and toughness that are a result of high-temperature tempering found with D-2. DC-53 is typically chosen as a replacement for D-2 in use for general purpose and precision dies. DC-53 is noted for causing less tool wear and machining times that are faster than D2 Tool Steel.
Benefits of DC-53 Tool Steel
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
Machines and grinds up to 40% faster than D2
Less residual stress after wire EDM
PropertiesDC-53 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
