Lincoln Electric, M9CRMOVN-12, MIG Wire, 1.2 mm; Non-Copper Coated, B9 (P91) Alloyed Steel, 33 lb

9CrMoVN is a low alloy steel MIG wire designed to weld equivalent ‘type 91’ 9CrMo steels modified with small additions of niobium, vanadium and nitrogen to give improved long term creep properties. Typically used for power plants, elevated temperature piping, oil refineries, and turbine casting applications.
