**8 tool steel Application
**8 steel Usage is same as the mold steel P*0 type, but as
a result of better hardenability, superior performance, can
make size large, high-grade plastic mold forming parts
Add hard processing
For improve Injection mould life up to *****0 times more, can be
implemented on pre hardened steel quenching and low temperature
tempering and hard way to achieve. In ******0 ºC preheat before
quenching when **4 hours, and then in ******0 ºC heat preservation
time (at least 2 hours), into the oil cooled to *****0 ºC oil
air cooling, hardness after quenching can reach *0 to *2 HRC, so as
to prevent cracking should be **0 ºC low temperature tempering
processing, immediately after tempering hardness can keep more than
*8 HRC .
Nitriding treatment
Nitriding treatment can get high hardness surface structure,
surface hardness after nitriding of ******0 hv
(*7 to *0 HRC) die life can reach more than 1 million times,
nitride layer with compact structure, smooth features, mould
stripping and wet air and alkali corrosion resistance improved.
Quenching and tempering (Q+T)
Quenching temperature **0 ~ **0 ° C, tempering
temperature **0 ~ **0 ° C, *0 to *5 HRC hardness
