Description

E410NiMo-15 is a martensitic stainless steel welding electrode with low-hydrogen sodium coating, containing 11.0-12.5% Cr, 4.0-5.0% Ni, and 0.40-0.70% Mo. It is suitable for all-position shielded metal arc welding (SMAW) with stable arc, minimal spatter, and excellent slag detachability . The deposited metal offers high strength, good corrosion resistance, and cracking resistance. Preheating is recommended for thick workpieces, and post-weld heat treatment (PWHT) at 580~620℃ (1-2 hours, air cooling, AC) is required .

Application

Ideal for welding ASTM CA6NM cast steel, 13%Cr-4%Ni series steels (e.g., Cr13Ni4Mo,Cr13Ni5Mo), and similar martensitic stainless steels . Typical applications include repair welding of hydropower turbine runners, valve bodies, high-pressure pipelines, and surfacing of cavitation-worn components. Also used for hardfacing repair of wear-resistant parts like crusher rolls and pump casings .
