Material Notes:

TLS 17-4 is a precipitation hardening, martensitic stainless steel that exhibits excellent resistance to atmospheric and chemical corrosion. TLS 17-4 exhibits an excellent combination of high strength and corrosion resistance. Because it resists attack from the corrosive vapors that are produced during molding of some plastic resins, it is used extensively in nozzle tips and feed screws in the plastic injection molding industry. The corrosion resistance also enhances extended tool storage in humid environments. Other common applications include plastic mold cavity inserts, plastic extrusion dies, fasteners, valves, and gears. Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
