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
- d) Perfect inspection method and inspection equipment
