90MnCrV8 | 1.2842

90MnCrV8 (1.2842) is a cold-work tool steel with high hardness and excellent wear resistance.
The material is mainly used in tool and machine construction where hard cutting, stamping or forming tools can be produced economically.
Due to its good hardenability, 90MnCrV8 is particularly suitable for high-stress applications requiring a precise cutting edge.
