ISO9001 AISI 321 S31803 S32205 Duplex Stainless Steel Pipes Full Hard Customized Seamless Tube
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.

Characteristics & Application
|
|
NO.1
|
Hot-rolled surface, annealed and pickled, can be used as cold-rolling material, industrial tanks and chemical devices. |
| 2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surface treatment to improve its chemical properties, N0.2B. could nearly satisfy comprehensive uses. |
| NO.4 | Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3. are used as bathtub building inner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-320 on the No.4. finish and has continuous streaks, mainly used as building ornaments, elevators, door of building, frontal plate etc. |
| BA | Cold-rolled, bright annealed and skin passed, the product has excellent brightness and good reflexivity like mirror, used for electrical appliances, kitchen apparatus, ornament materials etc. |
