Material specification
A cobalt ultrapure powder high speed steel containing 8.5% cobalt
Significantly improve the high temperature strength and red hardness
of steel. Its higher hardness and toughness greatly reduce the risk of
fracture and collapse blade.
The stability of dimension can be maintained during heat treatment."
Application
It can be used in the production of high performance cutting tools,
suitable for manufacturing gear cutting tools, taps, precision stamping,
the need for toughness and complex shape of precision die.
Delivery state: annealing state: 300HB Max.
Optimum hardness: HRC64-66
