Latrobe LSS™ S7 Shock-Resisting Tool Steel (ASTM S7)
Categories: Metal; Ferrous Metal; Alloy Steel; Carbon Steel; Medium Carbon Steel; Tool Steel; Air-Hardening Steel; Oil-Hardening Steel

Material Notes: TLS S7 Shock-Resisting tool steel is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes S7 tool steel a candidate for a wide variety of tooling applications. TLS S7 tool steel can be used successfully for both cold and hot work applications. It is recommended for cold work tools which require resistance to high impact and shock loading, such as shear blades, swaging dies, gripper dies, chisels, and punches. TLS S7 tool steel is also suitable for hot work tools where the operating temperature does not exceed 1000°F (538°C). For plastic injection molds, TLS S7 tool steel is available as a remelted, mold-quality product. The remelting process minimizes the number and sizes of nonmetallic inclusions in the steel, and thereby enhances the polishability for critical cavity, insert, and other tooling surfaces.
