Product Description

1.Application

    DC*3 steel is a new general purpose cold work die and mold steel whose strength and toughness approach those of high-speed steels.

    DC*3 steel, is an improvement over alloy tool steel D2.

    It has the following unique characteristics:

     • Higher hardness (****4 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 *0% faster than D2.

     • Less residual stress after wire EDMing.

2. Melting process

EAF+LF+VD
