Material Notes:
TLS A2 tool steel is a versatile, air-hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment. TLS A2 is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel. TLS A2 provides an effective combination of strength and toughness, tool performance, price, and a wide variety of product forms. Typical applications for TLS A2 tool steel include punches and dies, chuck jaws, cutting tools for woodworking, tooling for plastic injection, dowel pins, hammers, industrial knives, and gages.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
