Stainless Steel 321 is an austenitic chromium-nickel alloy that’s stabilized with titanium to avoid carbide precipitation. It generally contains 17–19% chromium, 9–12% nickel, and titanium in an amount at least five times the carbon content. This unique blend gives it remarkable resistance to intergranular corrosion, particularly at higher temperatures. On the mechanical side, SS 321 boasts good tensile and yield strength, impressive toughness, and excellent creep resistance, making it a great choice for continuous use in high-temperature and high-pressure settings.
