EDRO #8 Premium 420 Stainless Mold Steel
Categories:	Metal; Ferrous Metal; Stainless Steel; T 400 Series Stainless Steel
Material Notes:	EDRO #8™ is a chromium-alloyed stainless tool steel with the following properties: excellent corrosion resistance, superior polishability, good wear resistance, good machinability, and stability in hardening. EDRO #8™ is recommended for all types of molding tools, its special properties make it particularly suitable for molds with the following demands: corrosion/staining resistance, i.e., for molding of corrosive materials, e.g. PVC, acetates, and for molds subjected to humid working/storage conditions; Wear resistance, i.e., for molding abrasive/filled materials, including injection-molded thermosetting grades - also for molds with exceptionally long production runs, e.g. electrical/electronic parts; disposable cutlery and containers; High surface finish, i.e., for production of optical parts, such as camera and sunglass lenses, and for medical containers, e.g. syringes, analysis phials. EDRO #8™ is resistant to corrosive attack by water, water vapor, weak organic acids, dilute solutions of nitrates, carbonates and other salts. Information provided by EDRO
