These wires are made with an austenitic stainless steel sheath and rutile flux system with alloying controlled to maximise high-temperature strength and resistance to service embrittlement. Supercore 316LP is designed for all-positional welding including fixed pipework. Metal recovery is about 90% with respect to the wire. The Supercore 316L wire is not suitable for applications requiring PWHT or solution annealing – for these applications, it is recommended that Supercore 316LP is used.
Applications
These consumables are used for Mo bearing austenitic stainless steels with 1.5 – 3% Mo. They are also suitable for Ti or Nb stabilised and nitrogen-bearing or free machining versions of the above alloys (See Data Sheet). Type 316/316L steels are widely used for their good resistance to pitting, many acids and general corrosion.
