309 Stainless Steel Strip (SS 309 Strip) is an austenitic stainless steel material designed for high-temperature applications. With high chromium and nickel content, it provides excellent oxidation resistance, stable mechanical strength, and outstanding corrosion resistance even under severe service conditions.
At Jiangsu Cunrui Metal Products Co., Ltd., our 309 stainless steel strips strictly comply with ASTM, AISI, EN, and JIS standards. Each order comes with a mill test certificate, third-party inspection report, and traceable documentation to guarantee consistent quality and reliability.
Key Features & Advantages
Excellent Heat Resistance – Performs well in environments above 1000°C.
Superior Corrosion Resistance – Resists oxidation, scaling, and acidic conditions.
Reliable Mechanical Properties – Maintains stable yield and tensile strength under continuous exposure.
Certified Quality – Full traceability with inspection reports and third-party certifications.
Applications
SS 309 Strip is widely used in industries requiring both heat and corrosion resistance, such as:
Furnace linings and conveyor belts for heat treatment equipment
Petrochemical and chemical processing equipment
