Compared with ferritic stainless steel and austenitic stainless steel, duplex stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.

 

Due to its special advantages, duplex stainless steel is 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 bearing structure, with a good development prospect.
