Vacuum deairing with fine steel, it is easy for cutting after
quenching ,high hardness, good abrasion resistance ,dimension
stability and minimal distortion.
It is suitable for cutting tools, such as broach, filament hammer
and gauge and complex shape of cold mould, plastic mould, precise
Chemical Composition (%):
Quenching, 800 ~ 830 centigradecold oil.
Oilquenching cold die has crack sensitivity,so it should not be
quickly heated,it had better for a preheating in 650-750 centigrade
.The temperature of forging is 1130-1150 centigrade, eventually
temperature should be more than 800-850 centigrade, steel ingot
take upper limit temperature.while blank forging take lower
