ALFA ER410L Stainless Steel MIG Welding Wire is an extra-low-carbon solid MIG welding wire designed to deposit martensitic stainless steel weld metal. The weld deposit provides resistance to corrosion, oxidation, and hydrogen attack, making it suitable for stainless steel welding, surfacing applications, and industrial environments.
The wire is classified according to AWS/SFA 5.9: ER410L and JIS Z 3321: Y410.
