UNIFLUX VCM 225 is a continuous flux-cored welding electrode (wire) that is used to deposit 2-1/4% chromium-1% molybdenum steel weld when used to weld 2-1/4% chromium-1% molybdenum steel for which it was developed. Welding is protected by a shielding atmosphere of 100% carbon dioxide. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as heat treating, machining, and joining. Filing Code: SA-344. Producer or source: Unicore Inc., United Nuclear Corporation.
