W 1.2316

A prehardened corrosion resistant mold steel for high surface finish applications

W1.2316 is a 16%Cr 1% Mo with improved corrosion resistance properties, thanks to the addition of chromium and molybdenum.

The high cleanliness/homogeneity of the steel makes it specially adapted to fine polishing (mirror finish). This steel is commonly used for mold steel applications including cores, inserts and mold cavities working or stored in humid environments.

This grade is also used for the production of corrosive materials like PVC.
