Product Details
Ernicrmo-4 welding wire is mainly used for welding Hastelloy C-276 alloy and other nickel chromium molybdenum alloys by tungsten inert gas shielded welding and molten gas shielded welding, and can also be used for surface surfacing of steel. This kind of welding material has excellent corrosion resistance in various corrosive media, which is the ability to resist pitting corrosion and crack corrosion.
This welding wire can be used for welding different materials, including Hastelloy C-276 alloy and other nickel alloys, stainless steel and low alloy steel.
