Super Duplex 2507 Stainless Steel Pipes
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.
