Manufacturer ASME/ANSI B16.9 A403 WP304 SCH5-STD-SCH XXS Butt Welded Stainless steel Pipe Fittings 45 Degree Elbow
ASTM A403 pipe fittings are made from austenitic stainless steel as the raw material, and are manufactured by welding the pipes together.ASTM A403 steel pipe fittings have excellent corrosion resistance, high temperature strength, and low temperature toughness, and are widely used in various fields and industries for pipeline systems.
What Is ASTM A403 Standard
ASTM A403 standard specification for austenitic stainless steel materials, including various stainless steel grades such as 304, 316, 316L,321,904,31254 etc. The ASTM A403 specification the manufacturing, inspection, and testing requirements for stainless steel butt welding pipe fittings.It is classified and named according to the material type, size, and pressure rating of the pipe fittings to indicate their scope of application. In addition, the standard also specification the requirements for chemical composition, mechanical properties, heat treatment, surface treatment, etc.
ASTM A403 pipe fitings include WP304/304L,WP316/316L,WP904L,WP317/317L,WP31254,WP347,WP321,etc.It can adapt to the needs of pipeline applications in different working environments.
