Material Notes:
Description: CLC 1.2316 S grade is a 16%Cr 1%Mo mold steel with improved corrosion resistance properties, thanks to the chromium and molybdenum additions. Furthermore specific sulfur additions are considered to increase the machinability properties. The grade in the quenched tempered condition has a fully bainite martensite microstructure and can be delivered in the prehardened condition (300HB or 340HB). The grade is not designed for highly finish polished surfaces or etched surfaces. The grade is commonly used for mold steel applications including cores, inserts, molds… subjected to wet working conditions and / or storage conditions. The grade is also used for the manufacturing of corrosive materials like PVC.
