Iris Pipes and Tubes, based in Cairo, Egypt, stands out as a top manufacturer and supplier of high-quality Stainless Steel 321H Tubing, crafted for exceptional performance in high-temperature and corrosive industrial settings. These tubes are meticulously engineered from premium stainless steel that’s stabilized with titanium, which helps prevent intergranular corrosion and guarantees long-lasting durability. The Stainless Steel 321H Tubing is known for its impressive oxidation resistance, thermal stability, and mechanical strength, making it a perfect fit for demanding industrial applications. Iris Pipes and Tubes is committed to delivering reliable, high-performance tubing solutions that adhere to international standards, catering to industries like petrochemical, power generation, chemical processing, and aerospace with consistent quality.
The composition of Stainless Steel 321H Tubing primarily includes iron, chromium (17–19%), nickel (9–13%), and titanium, featuring a higher carbon content than the standard 321 grade to enhance creep strength at elevated temperatures. This austenitic stainless steel boasts a tensile strength of about 515 MPa, a yield strength of roughly 205 MPa, along with good ductility and toughness. The titanium stabilization plays a crucial role in preventing carbide precipitation during welding or thermal exposure, ensuring excellent corrosion resistance and mechanical stability even under high-temperature conditions.
