  • Description
  • Parameter
A prehardened structure mold steel (300 HB/31 HRC) with S, and corrosion resistant

W1.2316 S 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 its machinability properties. In quenched and tempered conditions, the grade has a fully bainite martensite microstructure and can be delivered in the prehardened conditions (300 HB or 340 HB).

The grade is not designed for highly finish polished surfaces or etched surfaces. This grade is commonly used for mold steel applications including cores, inserts, molds… subjected to wet condition and/or storage conditions. The grade is also used for the manufacturing of corrosive materials like PVC.
