ASTM A403 Stainless Steel Pipe Fittings Specification

ASTM A403 covers wrought austenitic stainless steel fittings for pressure piping and high-temperature service. These fittings are made from seamless and welded stainless steel pipes, with stringent specifications for chemical composition and mechanical properties. They are designed to withstand high pressure and corrosive environments, making them ideal for use in petrochemical, oil and gas, and power generation industries.
