AWS Class ERNiFeCr-1 filler metal rod and welding wire is a nickel-iron-chromium alloy that is used to weld other materials such as Inconel 718, 706 and other high-strength alloys. Its common alloy consists of Nickel (bal.), Iron (1721%), Chromium (2.5-9.5%), Niobium + Tantalum (4.75-5.5%), Manganese ( 0.35 ), Silicon ( 0.35 ) and some traces of Carbon, Copper and Titanium. Mechanical properties Tensile strength of an average of 850 Mpa, yield strength of an average of 480 Mpa and elongation of an average of 35%. The alloy is a great strength, oxidation, and toughness in high temperature, and is suitable in aerospace, power, and petrochemical markets.
