An Overview of Duplex Stainless Steel

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.

Does stainless steel corrode?

Stainless steel will corrode if the conditions are suitable severe, but they are significantly more corrosion resistant than carbon steels.

What is stainless steel used for?

Stainless steel is used in a plethora of applications, where alternative metals would not be suitable for either practical or aesthetic reason

When was stainless steel invented?

The generally accepted view is that stainless steels were developed by Harry Brearley (Sheffield, UK) around 1911.
