The composition of Stainless Steel 321H Pipes primarily includes iron, chromium (17–19%), nickel (9–13%), and titanium, which is added to prevent intergranular corrosion. They also contain controlled amounts of carbon, manganese, and silicon. The “H” in the name signifies a higher carbon content, which enhances their strength at elevated temperatures. These pipes boast excellent tensile strength, impressive yield strength, and toughness. They maintain their shape and stability even after prolonged exposure to high temperatures, resisting creep, scaling, and thermal fatigue, which ensures their long-term reliability. This unique composition makes Stainless Steel 321H Pipes perfect for critical applications where both corrosion resistance and high-temperature mechanical performance are crucial.
Stainless Steel 321H Square Pipes offer excellent resistance to intergranular corrosion, especially in high-temperature applications. They typically come in sizes ranging from 20 mm to 200 mm on each side, providing robust structural support and versatility for various industries.
Known for its resistance to oxidation and corrosion, SS 321H Seamless Pipes are manufactured without welds or joints, offering uniformity and strength. They are available in 6 mm to 300 mm diameter and are suitable for high-pressure and high-temperature environments.
