347 Stainless Steel Strip (SS 347 Strip) is a stabilized austenitic stainless steel that contains columbium/tantalum, which enhances resistance to intergranular corrosion after exposure to high temperatures. With excellent oxidation resistance and reliable mechanical properties, it is suitable for continuous service at elevated temperatures.
At Jiangsu Cunrui Metal Products Co., Ltd., our SS 347 strips are produced in accordance with ASTM, AISI, EN, and JIS standards. Every batch comes with material test certificates (MTC), third-party inspection reports, and traceable quality documentation to ensure compliance with international specifications.
Key Features & Advantages
Enhanced Corrosion Resistance – Stabilized against carbide precipitation, maintaining strength after long exposure to heat.
High-Temperature Performance – Reliable performance up to 870°C in continuous service.
Excellent Weldability – Maintains formability and weldability without post-weld heat treatment.
Certified Quality – Supplied with inspection certificates, ensuring trust and reliability.
Applications
SS 347 Strip is widely used in industries requiring high strength and corrosion resistance in extreme environments, including:
Chemical processing and petrochemical equipment
Furnace components, expansion joints, and high-heat exhaust systems
Aerospace and automotive thermal applications
Food processing and pharmaceutical industries where cleanliness is crucial
Boiler casings, heat exchangers, and pressure vessels
