Description
AISI W1 steel is a water-hardening tool steel, which has high hardness and wear resistance after quenching and tempering, but low hot hardness, poor hardenability, low plasticity and strength. The following data sheets summarize W1 steel properties such as chemical composition, physical and mechanical properties, etc. Note: Specified carbon ranges are designated by suffix numbers.
