7CrSiMnMoV
Its quenching temperature range wide,overheating sensibility little, flame heating avaiable, its have advantage for easy and simple to handle ,
low cost, save energy.. Hardenbility good , air cooling can harden. Its hardness reachable HRC62~64, and air cooling quenching little deformation.
The steel not only high strength but also better tenacity.
Deilvery status
Annealed , if need other process should be indicate in contract .
