    What is 321 Stainless Steel Strip?

    SUS 304 Mirror 8K Stainless Steel Coil (3)

    321 stainless steel is an austenitic nickel-chromium-titanium alloy celebrated for its outstanding wear and high-temperature resistance, along with superior creep strength. This alloy delivers robust performance across a range of concentrations and temperatures for both organic and inorganic acids, excelling particularly in oxidizing environments. Unlike 316L, 321 stainless steel is distinguished by its enhanced heat resistance. While it shares similarities with 304 stainless steel, the addition of titanium provides improved high-temperature durability and intergranular corrosion resistance. This composition helps prevent chromium carbide formation, ensuring reliability in various demanding applications.

    Features of 321 Stainless Steel Strip

    High-Temperature Resistance: Excellent performance in high-temperature environments, typically ranging from 430℃ to 900℃ (800°F to 1650°F), due to the addition of titanium which stabilizes the material.

    Corrosion Resistance: Strong resistance to oxidation and various forms of corrosion, especially intergranular corrosion, which is critical when the material is exposed to high temperatures.

    Wear Resistance: Good wear resistance, enhancing its durability in environments where friction and mechanical wear are factors.
