The Weld Star ER410 Stainless Steel TIG Wire is a martensitic stainless steel filler designed for welding and repair of 12% chromium stainless steels and for corrosion-resistant overlay on carbon steels. It is commonly used where resistance to heat, erosion, and abrasion is required in demanding service conditions.
Containing sufficient carbon to allow air-hardening, the weld metal transforms to a predominantly martensitic microstructure, delivering high strength and wear resistance. Pre-heat and post-weld heat treatment are recommended to achieve adequate ductility and toughness for many engineering applications, particularly in heat-affected or high-stress components.
