ASTM A403 WP321 pipe fittings
ASTM A403 WP321 is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800¨C1500¡ãF (427¨C816¡ãC). The alloy resists oxidation to 1500¡ãF (816¡ãC) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.
