Steel properties
The cobalt content of this high performance steel with good cutting capability ensures high red hardness and tempering retention. It is particularly suitable suitable in thermal stress situations and for intermittent cutting.
 
Applications
High performance milling cutters of all kinds, highly stressed twist bits and taps, shaped shear blades, for working high strength materials, broaches.
 
For complex geometry tools and for cold forming tools it is recommended that hardening temperatures near the lower limit of the indicated range should be used. The austenisation temperatures shown are valid for salt bath quenching. For vacuum quenching. it is recommended that they be reduced by 10 to 30 deg.C.
