High alloy high-speed steels stand out because of their extremely high level of hardness (approx. 60–67 HRc). As a result they can be exposed to operating temperatures of up to 600° C. They also stand out because of their high level of wear-resistance and increased chipping properties without lessening the cutting capability and cutting edge retention.
