MH ENiCrMo-4 is a nickel-based alloy welding electrode with low-hydrogen coating.It uses DC power supply. it applicable for the welding of C-276 alloy and other nickel-chromium-molybdenum alloy,nickel-based alloy, stainless steel and low-alloy steel and the surfacing of steel.
MHENiCrMo-4 welding electrode has excellent welding performance.
The deposited metal has excellent crack resistance and corrosion resistance, especially pitting corrosion resistance and crevice corrosion resistance.
ENiCrMo-4 and ENiCrMo-3 are both nickel-chromium-molybdenum welding electrodes, but they are commonly selected for different alloy systems and service environments. ENiCrMo-4 is mainly used for C-276 alloy and severe corrosion-resistant applications, while ENiCrMo-3 nickel welding rod for Alloy 625 is more suitable for Alloy 625, Alloy 800, Alloy 825, super duplex stainless steel and selected dissimilar metal welding projects.
| Product | Main Positioning | Typical Application | Buyer Selection Advice |
| ENiCrMo-4 Nickel Welding Rod | Nickel-chromium-molybdenum electrode for C-276 alloy and severe corrosion environments | C-276 alloy, corrosion-resistant alloy equipment, stainless steel and low-alloy steel surfacing | Choose ENiCrMo-4 when the project specifies C-276 alloy or stronger pitting and crevice corrosion resistance. |
| ENiCrMo-3 ENi625 Nickel Welding Electrode | Nickel alloy electrode for Alloy 625 and high-temperature corrosion-resistant alloys | Alloy 625, Alloy 800, Alloy 825, super duplex stainless steel and dissimilar metal welding | Choose ENiCrMo-3 when corrosion resistance, high-temperature strength and Alloy 625 compatibility are required. |
