    What is 309 Stainless Steel Strip?

    SUS 304 Mirror 8K Stainless Steel Coil (3)

    309 stainless steel is an austenitic stainless steel that performs comparably to 304 but with enhanced corrosion resistance and higher strength. Cold working 309 increases both its strength and hardness, though it does not respond to heat treatment.

    This robust alloy is valued for its excellent oxidation resistance, high-temperature resistance, and creep resistance. The low nickel content in 309 enhances its resistance to sulfur attack at elevated temperatures. Additionally, it is strong, ductile, and can be easily fabricated and machined, making it a versatile material for demanding applications.

    Features of 309 Stainless Steel Strip

    Features of 309 Stainless Steel Strip

    High Corrosion Resistance: Superior resistance to corrosion in a wide range of environments, particularly at elevated temperatures.

    High-Temperature Strength: Maintains strength and durability at high temperatures, making it ideal for use in high-heat environments.

    Oxidation Resistance: Excellent resistance to oxidation, which helps prevent surface degradation in high-temperature conditions.

    Creep Resistance: Good resistance to creep, enabling it to maintain structural integrity under prolonged exposure to high temperatures and stress.
