SKD11 High Alloy Steel Sheet

SKD11 Alloy Steel Plate:

SKD11 is a universal cold working die steel with high wear resistance and toughness, high carbon and high chromium alloy tool steel and vacuum degassing refined steel. The steel is pure, with good hardenability and small quenching deformation. After spherodizing annealing and softening treatment, the steel has good machinability and the carbide particles are fine and uniform, so there is no need to worry about the special addition of molybdenum and vanadium, which are strengthened by quenching cracking.

The steel is a kind of air-cooled hardened cold working die steel widely used in the world. Smelting by electric furnace and electroslag redissolved, high purity, better toughness, uniform structure, has good high temperature strength, toughness and high temperature fatigue resistance, can withstand temperature sudden change.

High hardness, high wear-resisting eutectic carbide uniform, good toughness, not easy to crack, hardness > after quenching; 62HRC. At 525℃, the nitriding treatment time is 20h/30h/60h, the nitriding layer depth is 0.25mm/ 0.30mm / 0.35mm, the surface hardness of parts is 1250HV; The nitriding treatment time was 2h at 570℃, the nitriding layer depth was 10-20 μm, and the surface hardness was 950HV.
