الوصف

Material uniformity, excellent machinability and polishability.High toughness and plasticity.
High abrasion resistance at high and low temperature.

Superb hardenability.

Outstanding high temperature strength and heat-resisting fatigue.
Small deformation during heat treatment, low trend of generating iron scale during air quenching.

Widely used in producing hot extrusion mould and mandrel, forging die of die hammer, forging press extrusion die, die edge for radial forging machine,aluminum copper and other alloy die cast mould.
