hot work mould steel H13

الوصف

Smelting characteristic: (1)high hardenability, high toughness, good ductility, high temperature performance. (2)The use of Electric arc furnace (EBT)+ refining(LF)+ Vacuum(VD)make the production of die steel are in high purity and good performance Highlight advantage: *-High hot strength and hardness *-good resistance to heat, good hot toughness, high resistance to temperature fatigue and wear in medium heat *-small heat deformation *-the tendency of the appearing of iron oxide skin are small in air-quenching *-Excellent corrosion resistanc Application: used in manufacture of extrusion dies, the mandrel, the forging mold for die forging hammer, forging press dies and die insert for precision forging machine as well as aluminum, copper die-casting mold
