S31803 duplex fittings have good welding performance, compared with ferrite stainless steel and austenitic stainless steel fittings. it is not like the welding heat-affected zone of ferrite stainless steel, and the plasticity and toughness are greatly reduced due to severe grain coarsening. Nor is it as sensitive to welding thermal cracks as austenitic stainless steel.
Due to its special advantages, S31803 duplex fittings have been widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, paper-making machinery and other industrial fields. In recent years, it has also been used in the field of bridge load-bearing structure.
It has a good prospect of development. Duplex stainless steel is composed of half ferrite phase and austenite phase in the quenched microstructure, and the content of the minimum phase may be up to 30%.
