Super Duplex Stainless Steel

FERRINOX® 255 is categorised as a super duplex (austenitic/ferritic) stainless steel.

This high performance alloy combines high mechanical strength (typically up to over 600 MPa yield strength) and good ductility with outstanding corrosion resistance to marine environments and a wide, diverse range of industrial media. These attributes result in the widespread specification of FERRINOX 255 as an alternative to 300 series stainless steel (such as type 316), standard 22% Cr duplex steel, precipitation hardening stainless steels (typical 17/4PH) and the alloy can in some instances reduces the need to choose a much higher cost nickel based alloy.

Success in Industry

The highly attractive combination of attributes provided by FERRINOX 255 has led to many years of successful application in Defence, Oil & Gas production, Chemicals processing, Pollution Control (FGD), Pulp & Paper Production, Architecture and Nuclear Engineering.
