Latrobe LSS™ 135M Nitriding Steel (ASTM A355 Class A)
Subcategory: Medium Carbon Steel; Alloy Steel; Metal
Close Analogs: Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
Material Notes: TLS 135M Nitriding Steel is a high-aluminum and chromium modification of AISI 4140 alloy steel. The aluminum addition promotes the formation of aluminum nitride compounds when tools manufactured from this steel are surface nitrided. The result is a nitrided surface which exhibits high hardness and good resistance to abrasion and wear, along with a strong and tough inner core in the piece. TLS 135M is supplied in the prehardened condition at a hardness of approximately 28 to 32 Rockwell C. In this condition, tools can be machined or ground, and then nitrided. Additional heat treatment is normally not required. Typical applications for TLS 135M steel include injection and extrusion feed screws, machine parts, pump parts, bushings, shafts, pinions, crankshafts, cams, camshafts, gears, valve sleeves, chuck jaws, dowel pins, and thread guides.Information Provided by Timken Latrobe Steel.
