Flux-cored wire made with an alloyed stainless steel sheath and rutile flux system. The Supercore 2507 combines easy operability, high deposit quality and exceptional bead appearance for downhand and HV welding.
Applications
Super duplex stainless steel pipe, plate, fittings and forgings have an approximate 50:50 microstructure of austenite with a ferrite matrix. This, coupled with the general alloying level confers:
- High strength compared with standard austenitic steels eg. type 316L
- Good general corrosion resistance in a range of environments
- High resistance to chloride-induced stress corrosion cracking (CSCC)
- High resistance to pitting attack in chloride environments eg. seawater. These alloys are finding widening application in the offshore oil/gas, chemical and petrochemical process industries, eg. pipework systems, flowlines, risers, manifolds etc
