Material Notes:
TLS L6 tool steel is a versatile, oil-hardening tool steel that is characterized by very good toughness. TLS L6 tool steel is suitable for use as tools, dies, and machine parts which require a good combination of hardness and toughness. The relatively high nickel content results in an alloy with greater impact toughness compared to the other common oil-hardening grades. Typical applications for TLS L6 tool steel include punches and dies, cold forming tools, and coining dies.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
