Stainless Steel 304 Welded Pipes are austenitic stainless steels composed mainly of iron, chromium (18–20%), and nickel (8–10.5%). This balanced composition provides excellent resistance to corrosion and oxidation, along with good mechanical strength and formability. Typical tensile strength ranges from 515–620 MPa, while yield strength is approximately 205–275 MPa. Welded construction ensures dimensional accuracy and consistent mechanical properties. These pipes also offer good toughness, ductility, and weldability, making them suitable for a wide range of pressure and temperature conditions.
