Application
DURAMAX E410NiMo-16 has a nominal composition (wt.-%) of 12 Cr, 4.5 Ni, 0.5 Mo. These electrodes are used for welding ASTM CA6NM (CA-6NM) castings or similar materials, as well as light-gauge Type 410, 410S, and 405 base metals. Weld metal deposited by the DM410NiMo electrodes are modified to contain less chromium and more nickel than weld metal deposited by DM410 electrodes. The objective is to eliminate ferrite in the microstructure, as ferrite has a deleterious effect on the mechanical properties of this alloy. Preheat and interpass temperature not less than 300F is recommended. Final post-weld heat treatment should not exceed 1150°F (620°C). Higher temperatures may result in rehardening due to untampered martensite in the microstructure after cooling to room temperatures.
