Product Catalog
Executive 410NiMo wire is designed to provide clean and consistent welds with excellent feedability and minimal clean-up. By maintaining tight control from the country of melt to the design of the spool Executive wire provides welders with the highest quality stainless bare wire. Executive 410NiMo is modified to contain less chromium and more nickel to eliminate ferrite in the microstructure as it has a deleterious effect on mechanical properties.
Application and Features
Executive 410NiMo is used to overlay mild and low alloy steels, suitable for turbines, valve bodies, high pressure piping, offshore and power generation. Final post weld heat treatment should not exceed 1150°F (620°C), as higher temperatures may result in re-hardening due to untampered martensite in the microstructure after cooling to room temperature.
This wire is also suitable for laser welding and WAAM applications (Wire Arc Additive Manufacturing, aka Metal 3D printing).
