Super duplex valve categorization

Super duplex valves can be categorized as follows:

* Super Duplex 2507,
* Super Duplex SAF 2507,
* Super Duplex UNS S32750
Duplex 2205, Duplex UNS S31803 Duplex SAF2205, Duplex SAF 2205 Super Duplex 2507, Super Duplex UNS S32750, Super Duplex SAF2507, Super Duplex SAF 2507

A category of stainless steel with high amounts of chromium and moderate nickel content. The duplex class is so named because it is a mixture of austenitic (chromium-nickel stainless class) and ferritic (plain chromium stainless category) structures. This combination was originated to offer more strength than either of those stainless steels. Duplex stainless steels provide high resistance to stress corrosion cracking (formation of cracks caused by a combination of corrosion and stress) and are suitable for heat exchangers, desalination plants, and marine applications
