Polmax was developed to be both highly polishable and corrosion resistant for extreme surface finishes such as in lens molds. Polmax has excellent polishability, good corrosion resistance, good wear resistance, good machinability, and good stability in hardening. It is used for applications where extreme surface finishes are required, such as lens molds, molds for compact discs and memory discs, and molds for med-ical applications. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties. It also includes information on corrosion resistance and surface qualities as well as heat treating and surface treatment. Filing Code: SS-918. Producer or source: Böhler-Uddeholm North America.
