The duplex material is a kind of ferrite-austenitic duplex stainless steel ,which is integrated conductive

properties both of ferrite and austenitic and provided with higher intensity as well as tenacity .on basis

of high content of chrome and molybdenum,the duplex material is endowed with all sorts capability of corrosion.

This kind of material possesses low heat expanding while its conductivity is higher than austenitic stainless

steel and owns good joining property ,It is applied in exchangers and pipelines of petroleum production,

processing and transportation/Crude oil and natural gas and sea water desalination / Chemical processing

and transportation equipment /Chloride solution processing,treatment and transportation /chemical tankers,

oil tankers and water processing pipelines.
