With excellent mechanical properties, corrosion resistance, and good weldability, it has a wide range of uses in the oil and gas industry, marine engineering, chemical industry and other industries. The length of the oil and gas pipelines laid by duplex stainless steel in the oil and natural gas industry has exceeded 850Km, most of which are 2205 duplex stainless steel seamless steel pipes (some of them are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); West-East Gas Pipeline Due to the strong corrosiveness of the natural gas medium in the project, the high-pressure pipelines are all made of 2205 duplex stainless steel.
It has good resistance to chloride ion stress corrosion cracking. It is a duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. Its yield strength is twice that of austenitic stainless steel. This feature makes the designer Reducing the weight when designing the product makes this alloy more advantageous than 316 and 317L. Due to the high content of chromium and molybdenum, the steel has excellent resistance to pitting corrosion and uniform corrosion. The microstructure of the dual phase head ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is also high.
