Stainless Steel 309H Square Pipes

The chemical composition of 309H stainless steel square pipes is as follows: Chromium (Cr) – 22-24%, Nickel (Ni) – 13-15%, Molybdenum (Mo) – 2-3%, Iron (Fe) – Balance. Additionally, it contains Carbon (C), Manganese (Mn), Phosphorus (P), Sulfur (S), Silicon (Si), and other trace elements.

Common uses of 309H SS square pipes include piping, tubing, and heat exchangers. Additionally, they are often used for decorative purposes due to their corrosion resistance and strength. The properties of 309H stainless steel square pipes include good corrosion resistance at high temperatures, superior tensile Strength, good formability and weldability, excellent oxidation resistance in both air and water environments, and strong mechanical properties.
