Stainless Steels

For duplex grades, what is the difference between S31803 (F51) and S32205 (F60)?

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

Which is better, nickel or stainless steel?

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

How is duplex stainless steel made?

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

Does duplex stainless steel rust?

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

Can stainless steel be hardened?

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

What is Fermonic®?

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

Can stainless steel be welded?

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

Can stainless steel be used at high temperatures?

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

What grades of stainless steel are non-magnetic?

Only austenitic stainless steels can be considered non-magnetic.

Is duplex stainless steel magnetic?

Due to it consisting of approximately 50% ferritic microstructure, duplex stainless steels are considered magnetic.

Is stainless steel non-magnetic?

Austenitic stainless steels are non-magnetic, whereas Ferritic, Duplex and Martensitic stainless steels are all magnetic.

What forms of corrosion can occur on stainless steels?

Pitting corrosion is the most common form of corrosion that can occur on stainless steels.
