Stainless tool steels such as 440C (and, for wet exposure, components interfacing in 316\/316L) trade some wear for corrosion resistance and may be specified for UWP components or where cleaning protocols demand it. Representative pelletizer supplier ranges place stainless and tool steels roughly from the low\u201150s to low\u201160s HRC depending on grade and geometry; exact setpoints should be coordinated with heat\u2011treat protocol and edge design.
