The ASTM A269 standard is developed by the American Society for Testing and Materials (ASTM). It specifies the material, chemical composition, mechanical properties and physical properties requirements of austenitic stainless steel mechanical pipes for general service.
Common materials of ASTM A269 stainless steel pipes include 304, 304L, 316, 316L, 316Ti, etc., with various specifications, including different outer diameters, wall thicknesses, lengths, etc., to meet the requirements of various engineering projects.
ASTM A269 steel pipes are suitable for stainless steel seamless and welded mechanical pipes with diameters from 1/8 inch (3.2mm) to 5 inches (127mm) for conveying gas, water, oil and other fluids.
