321 stainless steel is a versatile alloy prized for its corrosion resistance and high-temperature strength. The addition of titanium to 321 enhances its resistance to carbide precipitation, making it ideal for applications involving continuous service at elevated temperatures. While both 321 and 304 stainless steels offer good corrosion resistance, 321's superior performance at high temperatures and its resistance to carbide sensitization make it a more suitable option for applications demanding exceptional reliability in challenging conditions like exhaust systems, aerospace, petrochemical, and food processing.
