Properties And Applications

Basic-coated austenitic stainless steel electrode designed for welding 304H and similar 18Cr-8/10Ni stainless steels in high-temperature service, depositing a 19Cr-10Ni (308H) weld metal with controlled carbon (0.04-0.08%) to provide higher tensile and creep strength at elevated temperatures, good resistance to oxidation and scaling, and reliable weldability with stable arc performance, good fusion and a smooth bead profile, making it suitable for petrochemical and chemical process equipment, high-temperature piping, tanks, valves and overlay/surfacing applications.
