Sometimes you will find that strange phenomenon, when you walk to the beach, many are rusted metal, even stainless steel can even see it rusted. Why stainless steel will rust, corrosion？

    Yes, in a relatively high temperature and humidity,in the sea environment, or in contact with the acid, when 304,316 ... such as stainless steel can rust.

    To solve the problem of a lot of rust corrosion of stainless steel, the more economical way is to use duplex stainless steel. Duplex stainless steel is developed for the marine environment. Duplex stainless steel, as the name implies, it contains the ferrite and austenite structures.

Duplex stainless steel has the following benefits than average:

First: the strength of Duplex stainless steel is about twice as the austenitic and ferritic stainless steel. This can reduce the weight of the structure.

Second: extensive good resistance to seawater corrosion, especially stress corrosion cracking.

Duplex Stainless Steel used are：

A. 2205 is equivalent to UNS S31803 S32205, F51, F60, 1.4462, CD3MN

B. 2507 is equivalent to UNS S32750、 F53、 CE3MN、1.4410

C. UNS S32760 is equivalent to F55、1.4501、CD3MWCuN
