Brief Introduction

ASTM A403 WP316L-S Fitting Elbow is a high-performance corrosion-resistant stainless steel pipe fitting, strictly manufactured in accordance with ASTM A403 / ASME SA403 and ASME B16.9 standards. It is made of WP316L-S austenitic stainless steel (UNS S31603), a low-carbon variant of 316 stainless steel with added molybdenum, featuring superior corrosion resistance (especially to pitting and crevice corrosion), excellent weldability, stable mechanical properties and strong adaptability to harsh environments. As a key pipeline connection component, it is specially designed to change the direction of industrial pipelines, with compact structure, high dimensional accuracy and easy installation. It is suitable for low to medium pressure, normal to medium temperature working conditions, widely applied in various industrial systems conveying corrosive media, serving as a reliable and durable connection fitting for pipeline systems.
