Latrobe LSSâ„¢ D2 Tool Steel (ASTM D2)

TLS D2 tool steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Although other steels with improved toughness or improved wear resistance are available, TLS D2 provides an effective combination of wear resistance and toughness, tool performance, price, and a wide variety of product forms. TLS D2 is also available as an Electro-Slag-Remelted (ESR) product. The remelting process provides improved chemical homogeneity, refinement of carbide size, and the associated improvements in mechanical and fatigue properties. Typical applications for TLS D2 tool steel include rolls, punches, dies for blanking, forming, trimming, and thread rolling, shear knives, food-processing knives, and gages.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006.
