Duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series

stainless steels . [ Duplex " describes a family of stainless steels that are neither fully austenitic , like 304 stainless , nor purely ferritic , like 430 stainless .

The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy ( stress corrosion cracking resistance and high strength )

with those of an austenitic alloy ( ease of fabrication and corrosion resistance ) .

Application

a) Petroleum

b) Chemical industry

c) Instrument

d) Industrial transportation

e) Mechanical structure industry

f) Need high corrision ability pipe's industry, such as offshore industry etc

Advantages

a) Superior surface finish,

b) Better mechanical property

c) More precise dimension
