RW 410 / RW 410NIMO Stainless Welding Wire: Welding Wires for Martensitic and Ferritic-Martensitic Stainless Steels

RW 410 / RW 410NIMO is a welding wire class for martensitic or ferritic-martensitic stainless steels and overlay applications on carbon or low-alloy steels.

RW 410 Use RW 410 is used on similar-composition metals or weld overlays where corrosion, erosion and wear resistance are required.

RW 410NIMO Version RW 410NIMO is suitable for martensitic and ferritic-martensitic stainless steels such as 410/410S/405 in applications including hydro turbines.

Heat-Treatment Note Preheating and post-weld heat treatment may be required for ductility; for RW 410NIMO, post-weld heat treatment should not exceed 620°C.
