KX ERNiFeCr-2 Welding Wire Light Rod on Nickel Based Welding Wire Alloy
Product Description and Application
ERNiFeCr-2 is known as NO7718, SNi7718, NiFe19Cr19NbMo3
ERNiFeCr-2, a precipitate-hardened Ni-chromium alloy containing niobium and molybdenum, has high strength, good toughness and corrosion resistance at high and low temperatures at 700℃. The supply state may be solution treatment or precipitation hardening state. Used for welding INCONEL X750, alloy 718, 706, etc., used in high strength aero engine parts, ultra-low temperature liquid fuel rocket parts, etc.
