321 stainless steel is an austenitic chromium-nickel steel alloyed with titanium, enhancing its resistance to intergranular corrosion. It maintains stability in chromium carbide forming conditions, such as prolonged exposure to high temperatures. Resistant to scaling and oxidation in environments up to 900°C, 321 stainless steel bars are ideal for applications with intermittent heating within the carbide precipitation range. Commonly used in aerospace components, exhaust manifolds, heat exchangers, and expansion joints, this grade is also favored in the chemical processing industry. 321's resistance to high-temperature corrosion and overall durability make it well-suited for challenging industrial uses.
