ER410NiMo is a martensitic stainless steel solid wire with chemical composition featuring 11.0 – 12.5% Cr, 4.0 – 5.0% Ni, and 0.40 – 0.70% Mo. It is suitable for gas shielded welding (such as TIG/MIG) in all positions. During welding, the arc is stable, and the deposited metal exhibits excellent cavitation resistance, sand wear resistance,

and mechanical properties. Preheating is generally not required before welding; post-weld heat treatment (PWHT) at 580~620℃ for 2 hours (followed by air cooling,AC) is recommended as per application requirements. The deposited metal is machinable and suitable for pressure equipment.

Designed for welding ASTM CA6NM cast steel, 410/410S/405 stainless steel, and similar 13%Cr – 4%Ni series steels. Typical applications include pressure equipment  (conforming to pressure vessel standards), turbine blades, valves, high-pressure pipelines, and structural parts requiring corrosion and wear resistance.

Notice

1.Ensure the wire surface is clean and free of oil, rust, or moisture before use to avoid affecting welding quality.

2.Maintain gas purity and proper flow rate to prevent porosity and hydrogen-induced cracking.
