Excellent corrosion resistance against acid, alkali, and salt.
High strength-to-weight ratio, suitable for structural applications.
Seamless structure ensures leak-free performance in high-pressure environments.
Available in multiple shapes (round, square, rectangular, hexagonal).
Custom sizes and processing services available.
The corrosion resistance of 304 stainless steel comes mainly from chromium (≥18%), which forms a protective self-passivating oxide film on the surface. Alloying elements like nickel, molybdenum, titanium, niobium, and nitrogen further enhance toughness, mechanical properties, and resistance to harsh environments.
Seamless Pipe: Produced by hot rolling, cold rolling, or cold drawing. Features no welds, high precision, and excellent pressure resistance.
Welded Pipe: Made by welding, more cost-effective, suitable for low-pressure and general applications.
Round Pipe: Standard type, widely used in fluid transport and mechanical structures.
Special-shaped Pipe: Square, rectangular, hexagonal, semicircular, triangular, and octagonal pipes, used for decoration and special structural needs.
