Stainless Steels

Improvements have been made to the composition, reducing impurities and associated inclusions, plus improved heat treatment.

Ferralium is the original super duplex stainless steel, developed by Langley Alloys throughout the 1960’s and a patent in 1967.

Alloy 316 offers improved corrosion performance over Alloy 304, by virtue of an increased molybdenum content.

S32205 (F60) is produced to the upper end of the alloy specification of S31803 (F51), to give improved corrosion resistance.

With such a wide range of different alloys available, it is quite possible that several may all be suitable for a given application.

Duplex stainless steel is produced through a multi-stage steelmaking and forming process route.

As with all corrosion resistant alloys, duplex stainless steels can suffer corrosion when exposed to suitably corrosive conditions.

Stainless steels will work harden to some extent when subject to deformation i.e. bending, drawing, pressing.

Fermonic is a trademark belonging to Langley Alloys Ltd for high-performance austenitic stainless steels, such as our version of XM-19.

Stainless steels can be readily welded, with no great loss of corrosion performance or mechanical properties if undertaken properly.

The maximum operating temperature of stainless steels will vary, dependent upon the grade and microstructure.

Only austenitic stainless steels can be considered non-magnetic.
