1. Rationale
1.4108 is a martensitic stainless steel well known to the market as Cronidur 30. It was developed by a european steel mill using pressurized ESR-remelting practice. Due to the addition of nitrogen it was possible to replace carbon and to get hardness-values which normally can only be obtained by conventional martensitic grades with a considerably higher carbon content such as 440 B or 440 C. This is resulting in an extreme fine dispersion of carbides in the matrix and outstanding corrosion resistance. Due to these superior properties this steel also found its applications for the manufacture of surgical instruments. Therefore, this steel shall be incorporated in ASTM F 899.
