AISI H13 tool steel metal china supplier and stockholders. Otai Special steel is hot work alloy h13 tool steel china supplier of in round bar, plate, flat bar, sheet, square and block. SAE AISI H13 steel equivalent with JIS SKD61, GB 4Cr5MoSiV1 and DIN 1.2344 Tool Steel. H13-steel consists of chromium, molybdenum and vanadium and is known for its high hardenability and great toughness.
The molybdenum and vanadium act as strengthening agents while the chromium content helps the AISI H-13 tool steel to withstand softening when used at high temperatures. It also combines shock and abrasion resistance, has good red hardness, can resist rapid cooling and withstand premature heat checking. The H13 tool steel has good machinability, good weldability and good ductility and it can be formed by conventional means. So H13 steel applications is very range in hot forged mold, hot work tool.

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 DC53 steel block. we can saw cutting DC53 tool steel 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.
DC53 Form of Supply
For Cold work tool steel DC53, we can supply the steel round bar, steel flat bar, steel sheet, plate and square block. DC53 tool steel round bar can be sawn to your required length and size. Rectangular steel pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances.
DC53 steel Applications
The Cold work DC53 Tool Steel is found in Punches & dies, Draw & forum dies, Shear blades, Shredder knives, Thread & form rolls, Cold heading dies and Mill rolls & slitters.
Heat treatment JIS DC53 steel
The DC53 Tool steel heat treatment process can be broken down into 4 segments, Hardening (quench) & Tempering.Annealing & Normalized.
Most customers only need make the Hardening (quench) & Tempering for DC53 steel aplication.
JIS DC53 tool steel Forging
Slowly and uniformly Heat the DC53 tool steel to 700°C (1292°F),then rapidly heat the DC53 steel to 900-1040°C(1652-1904°F). After forging slowly cool down.
DC53 tool steel Hardening | quenching
Heat slowly the DC53 tool steel to 850°C(1562°F), Soak thoroughly at the temperature. the brought up to 1030°C(1886°F)oil quenching or air cool.
