Latrobe LSSâ„¢ S5 Shock-Resisting Tool Steel (ASTM S5)

TLS S5 Shock-Resisting tool steel is a silicon-manganese tool steel which exhibits the highest impact toughness among all of the "S" type steels. The high toughness and the ability to be hardened to 62 Rockwell C make TLS S5 an excellent choice for applications which require higher strength than S7 shock-resisting tool steel. The steel is typically hardened using an oil quench, but for simple geometries, the steel may be water quenched. Typical applications include pneumatic tools, shear blades, mandrels, heavy-duty punches, and stamping dies.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006.
