ASTM A403 WP317L-S Stainless Steel Reducer Butt weld Pipe Fitting B16.9

What is a stainless steel reducer?

A stainless steel reducer is a fitting used in piping systems to connect pipes of different sizes. It is designed to reduce the size of the pipe bore, allowing for the smooth flow of liquids or gases through the system. Stainless steel reducers are popular due to their durability, corrosion resistance, and suitability for various applications, especially in industries where hygiene and cleanliness are crucial, such as food processing, pharmaceuticals, and chemical processing.

What is grade SS317L/UNS S31703?

Grade SS317L/UNS S31703 refers to a specific type of stainless steel alloy. SS317L is a low-carbon version of SS317, which is an austenitic stainless steel that contains higher levels of chromium, nickel, and molybdenum compared to standard austenitic stainless steels. This makes SS317L more resistant to corrosion, especially in harsh environments such as chemical processing, petrochemical, and pharmaceutical industries.

UNS S31703 is the Unified Numbering System designation for this specific grade of stainless steel. It indicates a material that has a chemical composition meeting the UNS standard for stainless steel grade 317L. This grade is known for its excellent corrosion resistance, high strength, and good formability, making it suitable for a wide range of applications where resistance to corrosion and high temperatures is required.
