JIS DC53 tool steel china supplier and?stockholders,?Otai special?Steel are Special steel china suppliers of DC53 steel in round bar, flat bar, sheet , plate and steel block. we can saw cutting DC53 as your requirements size.?DC53 is improved new type of cold work die steel from SKD11 . The technical specification in Japanese industrial standard JIS G4404.

Cold work DC53 tool steel overcomes the insufficient of SKD11 high temperature tempering hardness and toughness of weakness, DC53 tool steel will fully replace SKD11 tool steel in the field of general and precision mould . Its toughness is 2 times of SKD11, ?DC53 toughness is more prominent in the cold work die.?Made of DC53 tools steel rarely appear crack and craze, greatly improving the service life.
The DC53 tool steel has a uniform distribution of fine carbides. It has great galling and wear and fatigue resistance. It has also a High temper resistance to support PVD & nitride surface treatments. And it has Machining and grinding properties are superior to most other tool steels.
