The AWS Class ER420 MIG and TIG filler welding wire is a high-chromium stainless steel alloy that contains about 13% chromium and has a low carbon content. This wire boasts excellent resistance to corrosion, oxidation, and wear, and it can create strong, resilient welds. Typically, it has a tensile strength of around 700 MPa and demonstrates good hardness characteristics after welding. ER420 is often used in its as-welded state or after undergoing post-weld heat treatment to enhance toughness and ductility. This filler metal is engineered to match or even surpass the properties of similar martensitic stainless steels.

AWS Class ER420 MIG and TIG filler welding wire is commonly utilized for welding martensitic stainless steels, particularly in applications where high hardness and wear resistance are essential. It’s perfect for fabricating and repairing components like turbine blades, valve seats, pump shafts, and cutting tools. Industries such as aerospace, oil and gas, and power generation depend on ER420 for both structural repairs and new assemblies. Its remarkable resistance to corrosion and scaling also makes it a great fit for high-temperature environments. To optimize mechanical properties for more demanding service conditions, post-weld heat treatment is frequently applied.
We provide high-quality electrodes, filler wire, MIG and TIG welding wires to a wide range of industries, including oil and gas, food, marine, petrochemical, power generation, and aerospace.
