★Application:
Hot/Warm WorkDies : Diecasting Dies and Parts, Forging Dies,Stamping Dies, ExtrusionDies.
Forming Tools : Rolling Dies
Others : Parts for Wear-proof
★ WEAR RESISTANCE PROPERTY IS QUITE EXCELLENT DUE TO RICHOXIDE (FECR)3O4LAYER WHICH IS STABLE THERMALLY AND IS HIGHLY ADHESIVE.
★ IT PERFORMS EXCELLENT PROPERTY BOTH IN GALLING RESISTANCEAND PREVENT-SCUFFING PROPERTY DUE TO RICH OXIDE (FECR)3O4.
★ CHANGE OF SHAPE AND DIMENSION IS VERY SMALL WITH ITS LOW PROCESS TEMPERATURE OF 520-550℃ WHICH ENABLES HARDENING SURFACE OF DC53 WITHOUT LOSING INNER HARDNESS.
