Duplex stainless steel is a very useful metal that is used the world over. It gets its name from the fact that it consists of two different grades of metal.Essentially, Duplex is a Fe-Ni-Cr alloy that has a two-phase ferritic-austenitic stainless-steel microstructure when it is at room temperature.
Duplex steels are characterised by high chromium (19–28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as “super duplex” due to its higher resistance to corrosion.
The advantage of combining ferritic and austenitic grades is that the resultant metal has a metallurgical structure that consists of two phases and therefore benefits from the properties of both microstructures.

We provide technical support and services for Stainless Steel Pipe including:
Stainless steel pipe packaging and shipping typically includes a tube or box that is sealed with inner lining material to prevent damage. The pipes are usually secured to the packaging with strapping and/or stretch wrap. The pipes can then be loaded onto pallets for shipping.
Depending on the size and weight of the shipment, it can be transported via truck, train, or plane. If freight is being shipped via truck, the freight company will typically provide the necessary straps and/or pads to secure the pipes to the truck. When being shipped via train or plane, the pipes will need to be packaged and secured according to the shipping company’s requirements.
