Dual Shield II 4130 SR
Dual Shield II 4130 SR is an all position flux cored wire for welding low alloy, high strength steels such as 4130. Ideal for offshore oil and gas topsides and platforms requiring high corrosion resistance with stress relieved high strength and low temperature impact toughness properties. Excellent welder appeal and mechanical properties after PWHT. Meets ANSI/NACE MR0175/ISO 15156-1. Typical Diffusible Hydrogen: <4 ml/100g of deposited metal.
