RW 430 / RW 430LNB / RW 430LNBTI Stainless Welding Wire: Ferritic Stainless Welding Wires
RW 430 / RW 430LNB / RW 430LNBTI is a ferritic stainless welding wire class for welding similar alloys, overlay applications and thermal spray use.
RW 430 Use RW 430 offers good ductility in the heat-treated condition and is used for similar-alloy welding.
Niobium Addition RW 430LNB is a low-carbon ferritic wire developed for automotive exhaust systems requiring corrosion and heat-fatigue resistance.
Niobium and Titanium Addition RW 430LNBTI is preserved as the ferritic version in the same class.
