W 1.2085

A resulfurized prehardened (300HB) and corrosion resistant mould steel

W1.2085 grade is a 16%Cr mold steel with improved corrosion resistance properties, thanks to the chromium addition. Furthermore, specific sulfur improve the machinability response.

The grade delivered in quenched and tempered condition has a fully bainite martensite microstructure and a typical hardness of 320 HB. The grade is not designed for highly finish polished surfaces or etched surfaces.

This steel 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.
