• ASTM A403 Pipe Fittings

Overview of ASTM A403 Stainless Steel Pipe Fittings

ASTM A403 pipe fittings are crafted from austenitic stainless steel, utilizing welding to form the pipe assemblies. These fittings are renowned for their excellent corrosion resistance, high-temperature strength, and robust performance in low temperatures, making them indispensable across various sectors and industries for sophisticated pipeline systems.

Understanding the ASTM A403 Standard

The ASTM A403 standard outlines the specifications for wrought austenitic stainless steel piping components, encompassing a diverse array of stainless steel grades such as 304, 316, 316L, 321, 904L, and 31254. This specification governs the production, inspection, and testing protocols for stainless steel butt welding fittings. It categorizes and labels fittings based on material type, size, and pressure rating to define their application scope. Moreover, the standard details essential criteria for chemical composition, mechanical properties, heat treatment, and surface finish.

Range of ASTM A403 Pipe Fittings

The ASTM A403 series includes grades such as WP304/304L, WP316/316L, WP904L, WP317/317L, WP31254, WP347, and WP321. These fittings are designed to meet the demands of pipeline applications in varied operational environments.
