ASTM A403 WP304H-S Fitting
ASTM A403 WP304H-S fittings are stainless steel pipe fittings. WP304H-S refers to a type 304H stainless steel. Type 304H is a high carbon version of type 304, designed for elevated temperature service. It has better creep resistance and strength at temperatures above 875°C (1607°F) compared to regular type 304.
Due to its chromium-nickel composition, these fittings offer excellent resistance to corrosion in many environments, including saltwater, acidic solutions, and other corrosive media.
ASTM A403 WP304H-S fittings have specific mechanical properties defined in the ASTM standard, including tensile strength, yield strength, and elongation after fracture, which ensure their durability and reliability under various operational conditions.
These fittings are manufactured according to specific dimensions and tolerances outlined in the ASTM A403 standard, ensuring compatibility with other components in the piping system.
They are widely used in high-temperature and high-pressure systems where corrosion resistance is critical. They are a reliable choice for applications requiring high-temperature resistance and corrosion protection. Their precise manufacturing standards and quality control measures make them suitable for a wide range of industrial and commercial uses.
