DC 53 Steel Grade
Toolman Special Steels is proud to produce and offer DC 53 Steel. DC-53 is a general purpose cold work tool steel with exceptional Toughness, Wear Resistance, Compressive Strength and Temper Resistance. DC53, is an improvement over alloy tool steel D-2. It eliminates the disadvantages of insufficient hardness and toughness. DC53 steel also has excellent machining characteristics and is well suited as a substrate for PVD surface treatments
DC 53 Steel Properties
-
Higher hardness (62-63HRc) than D2 after heat treatment.
-
Twice the toughness of D2 with a superior wear resistance.
-
20% higher fatigue strength than D2.
-
Smaller primary carbides than D2 protect the die from chipping and cracking.
-
Machines and grinds up to 40% faster than D2 .
