Specifications
Material :
UNS S31803
Steel Number :
1.4462
Forged material :
F51
Type :
wn forged flanges
Description

Material to UNS S31803 (and the other specifications listed below) is described as a duplex stainless steel with a
microstructure of 50:50 austenite and ferrite. The steel combines good mechanical strength (typically up to over
480 MPa yield strength) and ductility with moderate to good corrosion resistance in a variety of environments. By
agreement, the alloy can be supplied with a PREN (Pitting Resistance Equivalent) at >34 which ensures that the
resistance to pitting corrosion is as high as possible for this alloy grade. In addition, the steel offers good
resistance to stress corrosion cracking. Ambient and subzero temperature notch ductility is good. These attributes
mean that this duplex steel can be used successfully as an alternative to 300 series stainless steels in applications
where higher mechanical strength / lower weight is required and / or resistance to stress corrosion cracking is
needed

Welding :

The machining and welding of this grade of duplex
stainless steel presents no particular problems. Guidance
notes are available upon request.

Typical Applications :

Pumps, valves, chokes, Xmas trees, pipework / flanges,
bolting, connectors & manifolds. In oil and gas industry.
Equipment in brewing, power generation and chemical
engineering.
