MH ENiCrFe-3 is a nickel-based alloy welding electrode with low-hydrogen coating, which applicable for welding high-nickel or nickel-based alloys, and can also be used for welding dissimilar metals such as stainless steel and high-nickel steel or low-alloy steel.
Its content of Mn and Nb in the bead enables it have good crack resistance.
Because basic coating alloy welding rod, used for welding nickel base alloy, high temperature and creep resistant steel, heat resistant steel and low temperature steel, dissimilar steel welding.
It is suitable for pressure vessel manufacturing with operating temperature range from -196℃ to +650℃, and anti-oxidation peeling at +1200℃ (sulfur-free condition); The electrode and the deposited metal have high quality standards.
