Latrobe LSS™ 420 Supreme Plastic Mold Steel (AISI 420)

 

Subcategory: Stainless Steel; Mold Steel; Metal

Close Analogs: Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.

Material Notes:
TLS 420 Supreme is a specially-refined, mold-quality stainless steel that is engineered to provide supreme polishability, good corrosion resistance, and good wear resistance. TLS 420 supreme is manufactured using special melting and remelting techniques. These special melting practices along with proprietary forging practices result in the highest levels of microcleanliness and a homogeneous microstructure. TLS 420 Supreme is the material of choice for the manufacture of plastic molding tools that require the highest lens-quality polished finishes. Typical applications include molds for compact disks (CDs), medical laboratory equipment, optical lenses, and other components, which require critical surface finishes.
