ASTM A403 WP317L-S Concentric Reducer Buttweld Fitting B16.9​

317L stainless steel is a low carbon， high molybdenum austenitic stainless steel. It is a highly corrosion-resistant alloy with excellent resistance to acidic and alkaline solutions， especially in chloride environments.The low carbon content of 317L stainless steel makes it more resistant to the sensitization and subsequent intergranular corrosion that can occur in certain high-temperature applications. High molybdenum content (up to 3%) provides excellent resistance to pitting and crevices in corrosive environments.Due to its excellent corrosion resistance， 317L stainless steel is commonly used in applications that require high corrosion resistance， such as chemical processing plants， pulp and paper mills， and the food and beverage industry. It is also used in architectural applications such as roofing and cladding of buildings in coastal environments.

In the preparation process of SUS317L， the chemical composition needs to be strictly controlled to ensure the uniform distribution of alloying elements and the best performance. The corresponding domestic and foreign brands of SUS317L are 317L and UNS S31703. During the processing of SUS317L， the appropriate cutting parameters， coolant， etc. need to be selected according to the specific application requirements to ensure the processing quality.SUS317L has good resistance to hydrogen sulfide corrosion in the process of oil and gas exploitation and transportation， which can improve the safety of equipment. SUS317L has good resistance to high temperature stress fracture and can maintain good stability and corrosion resistance in high temperature stress fracture environment.
