321 Stainless Steel Angle/Section
321 stainless steel sections, an austenitic chromium-nickel steel alloyed with titanium, are known for their excellent resistance to intergranular corrosion and stability in high-temperature environments. The addition of titanium limits chromium carbide formation, enhancing high-temperature strength. These sections are ideal for applications involving intermittent heating within the carbide precipitation range, up to 900°C. Common uses include aerospace components, exhaust manifolds, heat exchangers, and expansion joints. They are also favored in the chemical processing industry. 321’s resistance to temperature-induced corrosion and overall durability make it suitable for various demanding industrial applications, especially where weldability and strength are crucial at high temperatures.
