The Duplex material is a kind of ferrite-austenitic duplex stainless steel, which is integrated conducive properties both of ferrite and austenitic and provided with higher intensity as well as tenacity;

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

The duplex material possess low heat expanding while its conductivity is higher than austenitic stainless steel;

The Duplex material owns good jointing property.

Exchangers and pipelines used in the equipment of petroleum production, processing and transportation/ Crude oil, natural gas and sea water desalination/ chemicals processing and transportation equipment/ chloride solution processing, treatment and transportation/ Chemical tankers, oil tankers and water processing pipelines
