Seamless tubes are also relatively common in our lives. I wonder if you have heard of Austenitic Stainless Steel Seamless Tube .
The austenitic stainless steel seamless tube is stainless steel in which the ferrite phase and the austenite phase in the solid-quenched structure are both smelted and manufactured. The actual phase ratio is that ferrite occupies 45-55%, and the corresponding austenite occupies 55-45%. The excellent performance of 2205 duplex stainless steel is ensured by an appropriate ratio of two-phase structure.
The length of the oil and gas pipelines laid by duplex stainless steel in the oil and gas industry has exceeded 850Km, most of which are austenitic stainless steel seamless tubes (some of them are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); The transporting natural gas medium is highly corrosive, and the high-pressure pipelines are all made of austenitic stainless steel seamless tube material.
Relatively speaking, the performance of Ferritic Stainless Steel Seamless Pipe and Tube is not suitable for this.
