SUPER DUPLEX FLANGES : PRODUCT

Super duplex is an austenitic ferritic alloy that contains iron, chromium, nickel and hints of molybdenum. The term super duplex originated in the 1980s, it was used to represent high alloy, high performance duplex steels with a high pitting resistance equivalent. Super duplex flanges also have high corrosion resistance levels. They are also highly resistant to general corrosion in acids. Thus, having these characteristics, super duplex flanges were preferred in a number of marine and chemical industries replacing 300 series stainless steel, high nickel super-austenitic steels and nickel-based alloys.

We manufacture flanges from sizes ½ to 36 and in dimensions from 15mm to 600mm.

SUPER DUPLEX FLANGES : TYPES

Super duplex Flanges can be declassified into various types:

  • Super duplex Blind Flange
