Duplex stainless steel is austenitic-ferritic type stainless steel. It has excellent resistance to stress corrosion, pitting and pore corrosion, high acid resistance; higher strength and plastic toughness than austenitic steel, and lower coefficient of linear expansion. It is developed for vessels, pipes and parts that are difficult for general stainless steel to perform.Refining, fertilizer, paper, petroleum, chemical and other seawater resistant high temperature resistant concentrated nitric acid and other heat exchangers and cold showers and piping devices.Bridges, aircraft, ships, automobiles and decorative building materials for coastal cities and chemical zones, etc.

Duplex stainless steel tube advantage

Duplex stainless steel pipe has good welding properties, compared with ferritic stainless steel and austenitic stainless steel, it is neither like ferritic stainless steel welding heat-affected zone, due to severe coarsening of grains and plastic toughness is significantly reduced, nor is it like austenitic stainless steel, which is more sensitive to welding heat cracking.
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, and in recent years has also been studied for bridge load-bearing structure field, with good prospects for development.
Duplex stainless steel is in its solid hardening organization in the ferrite phase and austenite phase each half, the general minimum phase content of perhaps 30%.
