SKS3(9CrWMn) die steel is low alloy cold work die steel.The steel has a certain degree of hardenability and wear resistance, quenching deformation is small, uniform distribution of carbide particles small, usually used to make small cross section and shape more complex cold stamping die and various gauges and tools.
This kind of steel is often used statically and dynamically stressed components for vehicles, engines and machines. For parts of larger cross-sections, crankshafts, gears
T10A W1-9 C105W2 SK105 SK95 Universal low hardenability cold work mould steel, advanced high carbon tool steel
The steel is roughed in annealed state, then quenched and tempered to high hardness, and then refined.High wear resistance and mirror finish are obtained.Low carbon martensite quenching can improve wear resistance and toughness, prevent and reduce deformation and cracking
DC53 is a new type of cold working die steel modified from SKD11 by datong special steel, whose technical specification is contained in Japanese industrial standard (JIS) G4404.It overcomes SKD11 high temperature temper hardness and toughness weakness, will be in the general and precision die field comprehensive replacement of SKD11 high strength and toughness universal cold die steel.
SKD61 hot die steel has beautiful metal luster, vacuum degassing refining treatment, pure steel, spheroidizing annealing softening treatment, good cutting performance.Reinforced elements vanadium, molybdenum special addition, excellent wear resistance.
After heat treatment and cold drawing, it has high strength and certain flexibility and plasticity.Under the same surface condition and full quenching, the fatigue limit is the same as the color alloy spring.It is mainly used for spring of smaller size, such as pressure regulating spring, force measuring spring, round and square spiral spring or drawn into steel wire for spring of small machine.
The M42 steel has a high hardness of 68~70HRC, good heat hardness, high temperature hardness and easy grinding. but the toughness is slightly poor, and the lower limit should be used for quenching. Due to its good grindability, it can be used to manufacture a wide range of high precision and complex tools.
