Property:
Steel suitable for air hardening,It’s characterized by fairly good dimensional stability during heat treatment. It remains high wear resistance up to temperature of around 600℃.
This steel also possesses excellent toughness and high level insensitivity to thermal shock and thermal fatigue. A nitriding type surface treatment can be carried out on this steel to increase the service life of the tooling.
Application :
Hot punches and dies for blanking,bending,swaging and forging ,hot extrusion dies for aluminum,cores,ejector pins,inserts and nozzles for aluminum,copper ,tin and lead die casting.
