For an alloy to be beaten into sheets or plates, ductility and malleability are two vital characteristics. While not completely austenitic with regards to its microstructure, the 2205 Duplex Steel Plate accounts for about 50% austenite, which gives the alloy good ductility. Therefore, making it easier to be formed into thin plates or even sheets. Generally, it can be assumed that ductile or malleable metals have low toughness and do not retain their shape, simply because this property makes it possible to manipulate its shape. However, since the ASTM A240 UNS S32205 Duplex Sheet has a partial ferritic microstructure, it inherits toughness, which is the highlight of a ferritic class of stainless steel.
The unique combination of high ductility with superior toughness is the reason why many Duplex Plate Suppliers favor the use of this metal for various projects across different industries. Industries that build machinery or pieces of equipment rely on standards set by international organizations to achieve good standardized results. The adoption of standards to produce the ASTM A240 UNS S31803 Duplex Steel Plate, not only delivers a good product but also optimizes the overall end product use. For instance, this standard, in particular, is used as a reference point for pressure vessels. As pressure vessels deal with different pressure levels, it is necessary that the material used to build them be thoroughly capable of withstanding these stress levels. Specifications like the ASTM A240 specifies the mechanical properties of Duplex Stainless Steel Plate in addition to the chemical requirements.
