Product Description
Product Description
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.
321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automobile industries [1]. However, the "stainlessness" of stainless steel is not absolute. Due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, and temperature will have a greater impact on the corrosion resistance of stainless steel. For example, long-term use within the sensitization temperature range of 450 to 850°C will cause intergranular corrosion of stainless steel. The mechanism is that C combines with Cr at the grain boundary to form Cr23C6 and precipitate, which reduces the Cr content at the grain boundary. This is the so-called "chromium depletion". The Cr element is one of the main elements that inhibit intergranular corrosion. When the Cr content at the grain boundary is less than 12%, the probability of intergranular corrosion will increase.
