Flux-cored wire made with an austenitic stainless steel sheath and rutile flux system. Supercore 347HP is designed for all-positional welding from 1G/2G up to 5G/6G fixed pipework. Metal recovery is about 90% with respect to the wire.
Applications
Used to weld titanium and niobium stabilised 18/8 high carbon stainless steel types 321H and 347H. Applications include catalytic crackers (cat crackers), cyclones, transfer lines, furnace parts, steam piping, superheater headers, and some gas and steam turbine components, used in petrochemical, chemical process plants and power generation industries.
