Stainless Steel 321 Bars are primarily made up of iron, chromium (17–19%), nickel (9–12%), and titanium (which helps stabilize against chromium carbide formation), along with small amounts of carbon, manganese, and silicon. This alloy is known for its outstanding resistance to intergranular corrosion, high-temperature oxidation, and thermal fatigue. On the mechanical side, it provides good tensile strength, yield strength, and elongation, making it perfect for demanding structural applications. The inclusion of titanium enhances weldability and prevents sensitization, all while ensuring stability during high-temperature use. In summary, SS 321 bars are a blend of strength, durability, and dependable performance even in elevated temperatures.
