Austenitic Stainless Steel WP316LN Pipe Fittings

ASTM A403 WP316LN Pipe Fittings are manufactured as wrought austenitic stainless steel fittings intended for pressure piping applications. These fittings are produced from stainless steel forgings, bars, and seamless or welded materials, and undergo heat treatment along with chemical and mechanical testing to ensure compliance with specified standards. The material composition is carefully controlled to meet required elements such as carbon, manganese, and nitrogen, making them suitable for demanding industrial environments including oil & gas and process piping systems.

ASTM A403 WP316LN Pipe Fittings are available in a range of configurations such as 45° and 90° elbows, long radius elbows, tees, reducers, and other standard buttweld fittings. Sizes typically range from ½” up to larger nominal bores, depending on project requirements. These fittings are manufactured in accordance with ASTM A403 and related specifications to ensure dimensional accuracy and performance.

ASTM A403 WP316LN Pipe Fittings are known for their improved strength and corrosion resistance, making them suitable for use in piping systems handling water, oil, gas, and chemicals. The products are packed in secure wooden boxes or crates to prevent damage during transit and are supplied as per customer specifications with appropriate quality assurance.
