AWS A5.22 E410NiMoT0-1/-4 or E410NiMoT1-1/-4
E410NiMoT-4 is a flux-cored wire for single or multi pass welds on multi-pass welds on AISI types 403, 405, 410 and 420 and for welding CA-6NM castings stainless steels. E410NiMoT-4 is noted for its low spatter generation, excellent bead shape and appearance and ease of slag removal. It has very good deposit efficiency when used for flat and fillet welds of medium and heavy thickness plates. It has been designed to be used with 75-80% Argon + 20-25% CO2 mixed shield gas.
E410NiMoT-4 provides hard as welded deposits with optimum abrasion resistance. When used as an overlay material cross-check cracking is to be expected as this is how the deposit stress relieves itself. E410NiMoT-4 is used extensively in the fabrication of 12% Cr, 4.5% Ni, and 0.5% Mo stainless steel structures. Typically, this alloy is used in fabricating and repairing hydroelectric turbines. When used to weld AISI types 404, 406 and 410 pre-heat and post-weld heat treatment is required. With correct procedures, hardness levels of less than 23 Rockwell C are possible. The deposit is fully martensitic and the hardness and tensile strength depend on the post-weld heat treatment procedures used. A Stress Relief (SR) of 600°C (1,115°F) for one hour is recommended toobtain maximum properties. TYPICAL WELD METAL CHEMISTRY (Tested with 80% Argon + 20% CO2 Shield Gas)
