S31803 duplex stainless steel pipe
Product Details
Description
Dual phase stainless steel pipes have good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, they are not like the welding heat affected zone of ferritic stainless steel. Due to severe grain coarsening, their plasticity and toughness are significantly reduced, and they are not as sensitive to welding hot cracks as austenitic stainless steel.
Duplex stainless steel, due to its special advantages, is widely used in industrial fields such as petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, papermaking machinery, etc. In recent years, it has also been studied and used in the field of bridge load-bearing structures, with good development prospects.
