Welded Stainless Steel Seamless Pipe Tube 201 304 304L 316 316L 2205 2507 310S
As an alloy the benefits of using super duplex 2507 are abundant. Right from its corrosion resistance properties to its strength, businesses across the world appreciate these properties of 2507 Super Duplex Seamless Pipe and Tube. With a dual microstructure phase, the weldability properties of this alloy are classified as good, which is why it is possible to achieve a relatively strong and durable Super Duplex Welded Tube. However, one simply cannot deny the fact that, despite being a costlier alternative, the load or pressure bearing ability of a 2507 Super Duplex Seamless Pipe is almost 20% higher in comparison to its welded counterpart.
