UNIFLUX 90 is a continuous flux-cored welding electrode (wire) for welding in carbon dioxide shielding gas in the flat groove and horizontal fillet positions. It was developed to weld high-strength low-alloy steels, but it can be used successfully to weld other low-alloy steels and carbon steels. It is used to deposit typically 2.40% nickel steel weld metal with good low-temperature impact properties. Uniflux 90 is used widely in shipbuilding and other fabricating industries. It provides around 85,000 psi tensile strength and around 25 foot-pounds Charpy V-notch impact at -60 F. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on low temperature performance and corrosion resistance as well as heat treating, machining, and joining. Filing Code: SA-362.
