Application:
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.
