The **Stainless Steel 321 Pipes** are made from titanium-stabilized austenitic stainless steel, featuring 17–19% chromium, 9–12% nickel, along with small amounts of carbon, manganese, and silicon. The addition of titanium helps prevent carbide precipitation during welding, which in turn improves their resistance to intergranular corrosion. On the mechanical side, these pipes boast a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of up to 40%, ensuring they are both formable and tough. They maintain their structural integrity at temperatures reaching up to 870°C, making them perfect for extended use in heat-heavy environments.
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.
