definition

The definition of 2205 duplex stainless steel pipe is a stainless steel with half of the ferrite phase and austenite in its solid quenching structure, referred to as 2205 stainless steel pipe, also called 2205 duplex steel pipe. The actual phase ratio is that ferrite accounts for 45~55%, and the corresponding austenite accounts for 55~45%. The excellent performance of 2205 duplex stainless steel is guaranteed by the appropriate proportion of the two-phase structure.
2205 duplex stainless steel pipe has excellent mechanical properties and corrosion resistance, as well as good weldability, and has a wide range of uses in the oil and gas industry, marine engineering, chemical industry and other industries. The length of oil and gas pipelines laid with duplex stainless steel materials in the oil and gas industry has exceeded 850Km, most of which are 2205 duplex stainless steel seamless steel pipes (some are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes).

Performance and Comparison

2205 dual-phase steel pipe combines the most beneficial properties of ferrite and austenite, and 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. The yield strength is twice that of austenitic stainless steels, a feature that allows designers to reduce weight when designing products, giving this alloy an advantage over 316, 317L. Due to the high content of chromium and molybdenum, the steel has excellent resistance to pitting and uniform corrosion. The microstructure of the duplex head ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.
