304 stainless steel is a balanced austenic steel that is widely applied and versatile in a wide range of products, finishes, and forgings. Chemical composition, weldability, oxidation, mechanical properties, and corrosion resistance allow this austenitic steel to perform best at relatively low cost. Austenitic steel performs well in cold work hardening.
We are a manufacturer, supplier, and exporter of 304 stainless steel pipe fittings that are produced in a variety of designs, styles, specifications, grades, and sizes, with each fitting meeting the needs of an industry. 304 and 304L stainless steel pipe fittings are manufactured in accordance with ASTM A-403 and ANSI B16.9 / 16.28 / MSS SP-43 / ANSI B 16.25 weld bevel standards. We manufacture these 304 stainless steel pipe fittings in various shapes, such as 304 stainless steel pipe fittings elbow, tee, reducers, cap, bend, point, collar, cross, etc.
