DC53 Steel Equivalent Material
DC53 special steel and its equivalent material are a new type of cold work die steel from Japan Daido steel, improved on SKD11. The heat treatment hardness of the DC53 steel is higher than SKD11, reaches 62-63HRC after tempering at 520-530℃. DC53 exceeds SKD11 in strength and wear resistance, and the toughness is twice that of SKD11, which is more prominent in cold work die steel. The tools made of DC53 rarely have cracks, which greatly improves the service life.
You can find DC53 steel equivalent to ASSAB 88 / Cr8Mo1VSi from GB/T standard / modified A8 from FINKL / SLD8 from HITACHI / K340 from BOHLER
DC 53 Steel Advantages
