    What is 347 Stainless Steel Strip?

    SUS 304 Mirror 8K Stainless Steel Coil (3)

    Type 347 is a stabilized austenitic stainless steel, similar to type 304, but with the addition of columbium and tantalum. The inclusion of columbium provides stabilization, making the steel resistant to chromium carbide precipitation. This feature is particularly advantageous for welded parts that cannot be sufficiently annealed or for components that must operate within the 800 – 1600°F (427 – 816°C) temperature range.

    Features of 347 Stainless Steel Strip

    Features of 347 Stainless Steel Strip

    Corrosion Resistance: Alloy 347 stainless steel strip offers corrosion resistance comparable to type 304. It is specifically developed for use in environments within the 800 – 1600°F range, where unstabilized alloys like 304 are susceptible to intergranular attack due to chromium carbide precipitation.

    Temperature Performance: In the specified temperature range, alloy 347 stainless steel exhibits superior overall corrosion resistance compared to alloy 321 stainless steel. It also performs slightly better than alloy 321 in highly oxidizing environments, withstanding temperatures up to 1600°F (816°C).

    Weldability: The stabilized nature of type 347 makes it ideal for welded parts that cannot undergo prolonged annealing. It ensures the material maintains its integrity and corrosion resistance even after welding.
