Material Notes:
TLS 440C Stainless Knife Steel is a high-carbon martensitic stainless steel which exhibits an attainable hardness of approximately 60 HRC. The high carbon content results in a hard matrix and numerous chromium carbides in the microstructure, which in turn provide excellent wear resistance and retention of cutting edges. TLS 440C stainless knife steel should be considered for applications such as specialty knives, industrial knives, scissors, surgical knives, and other applications which require a combination of corrosion resistance, wear resistance, or edge retention.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
