JIS G4305 SUS347 Stainless Steel Plate Stock

Gangsteel keeps a good selection of JIS G4305 SUS347 stainless steel plates in our stainless steel stock. Niobium stabilization makes this grade highly resistant to intergranular corrosion at elevated temperatures.

Key Characteristics of SUS347

With niobium addition, SUS347 prevents carbide precipitation during welding and high-temperature service. In our stainless steel stock, plates are available in both hot-rolled and cold-rolled conditions.

Common Applications

This grade is commonly used in boilers, heat exchangers, aircraft exhaust systems, petrochemical piping, and refinery equipment operating at temperatures up to 800–900°C.

Available Stock Specifications

Regular sizes in our stainless steel stock:

• Thickness: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm
• Width: 1500mm, 2000mm
• Length: 3000mm, 6000mm Finishes: 2B, No.1, and BA.

Advantages and Comparisons
