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.
Neith Metals’ Stainless Steel 321 Flat Bars are extensively utilized in high-temperature and corrosive settings. They are perfect for applications such as heat exchangers, chemical processing equipment, jet engine components, exhaust manifolds, and furnace parts. The alloy’s stability and resistance to oxidation make it suitable for continuous operation at temperatures reaching up to 900°C. Moreover, its excellent weldability and formability make it ideal for use in pressure vessels, refineries, and power plants, where maintaining long-term structural integrity and resistance to thermal fatigue is essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
