RW 420
RW 420 / RW 420C Stainless Welding Wire: 13% Cr Martensitic Stainless Welding Wires
RW 420 / RW 420C is a 13% Cr martensitic stainless welding wire class for similar stainless steels and hard, wear-resistant surface applications.
RW 420 Use RW 420 is used for welding similar martensitic stainless steels and for obtaining hard surfaces.
RW 420C Version RW 420C is preserved as the higher-carbon version compared with RW 420.
Surface Applications Overlay and thermal spray applications target wear resistance.
