ASTM A403 WP304H-S Fitting Elbow is a high-temperature resistant stainless steel pipe fitting, strictly manufactured in accordance with ASTM A403 / ASME SA403 and ASME B16.9 standards. It is made of WP304H-S austenitic stainless steel (UNS S30409), a high-carbon variant of WP304-S, featuring excellent high-temperature strength, good corrosion resistance, superior weldability and stable mechanical properties. As a key pipeline connection fitting, it is mainly used for changing pipeline direction in industrial systems, with compact structure, easy installation and strong adaptability. It is suitable for low to medium pressure, high-temperature working conditions, widely applied in various industrial fields, and can stably convey high-temperature media such as steam, hot oil and high-temperature gas, serving as a reliable connection component for industrial pipeline systems.
