The primary alloying element in Stainless Steel 321 is chromium, typically comprising around 17-19%. Chromium provides corrosion resistance, while titanium is added to improve high-temperature stability and prevent carbide precipitation during welding or prolonged exposure to elevated temperatures.
Stainless Steel 321 is most suitable for temperatures ranging from 800°F to 1500°F (427°C to 815°C). It excels in high-temperature environments due to its titanium stabilization, which prevents carbide precipitation and maintains corrosion resistance under prolonged heat exposure.
Typical dimensions of Stainless Steel 321 flat bars vary, with widths ranging from 20 mm to 150 mm, thicknesses between 3 mm and 50 mm, and lengths up to 6 meters, customizable based on specific requirements.
You’ll find Stainless Steel 321 Flat Bars commonly used in chemical processing equipment, furnace components, heat exchangers, and aerospace parts. Their ability to resist oxidation, scaling, and intergranular corrosion makes them ideal for high-temperature and challenging environments. They’re also utilized in structural components, shafts, and mechanical parts where durability, reliability, and a long service life are crucial. Industries such as petrochemical, power generation, and manufacturing depend on 321 flat bars for essential applications that require strength and consistent performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
