Bosega Pipes and Tubes, located in Cape Town, South Africa, has made a name for itself as a top-notch manufacturer and supplier of high-quality Stainless Steel 321H Tubing. With a reputation for precision engineering, durability, and outstanding performance, Bosega provides tubing solutions that are specifically designed to thrive in high-temperature and corrosive industrial settings. The Stainless Steel 321H Tubing is a titanium-stabilized austenitic stainless steel that boasts a higher carbon content, which enhances its strength and resistance to intergranular corrosion. Catering to industries like chemical processing, power generation, aerospace, and petrochemical, Bosega guarantees that its tubing products adhere to strict quality standards, ensuring long-lasting reliability, safety, and efficiency in critical applications that demand superior thermal and mechanical performance.
The composition of Bosega’s Stainless Steel 321H Tubing includes iron, chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), and titanium as a stabilizer. The increased carbon content compared to 321 enhances its tensile strength and creep resistance at high temperatures. Mechanically, it showcases excellent strength at elevated temperatures, good ductility, and remarkable resistance to intergranular corrosion and oxidation. This combination of mechanical strength, corrosion resistance, and weldability guarantees long-term durability in challenging thermal environments. These features make Stainless Steel 321H Tubing perfect for applications where high-temperature stability and structural integrity are essential.
