The primary alloying element in Stainless Steel 321H is titanium (Ti), which stabilizes the steel and prevents carbide precipitation during welding. It also contains chromium (Cr) for corrosion resistance and higher carbon content for increased strength at elevated temperatures.
Stainless Steel 321H is most suitable for high-temperature applications in the range of 427°C to 816°C (800°F to 1500°F). It offers excellent oxidation resistance and stability in these temperatures, making it ideal for heat exchangers and furnace components.
Typical dimensions of a Stainless Steel 321H flat bar range from 3mm to 150mm thickness, 25mm to 600mm width, and up to 6 meters in length. These dimensions vary based on manufacturer specifications and customer requirements.
Stainless Steel 321H Flat Bars find their place in various applications, including chemical processing equipment, furnace components, heat exchangers, and aerospace uses. Their ability to resist oxidation, scaling, and intergranular corrosion makes them ideal for high-temperature and corrosive environments. Additionally, they are utilized in mechanical parts, shafts, and structural components where durability, reliability, and extended service life are crucial. Industries such as petrochemical, power generation, and manufacturing depend on 321H flat bars for applications that require consistent strength, performance, and longevity.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
