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

Austenitic stainless steels retain their impact strength at very low temperatures.

Only austenitic stainless steels can be considered non-magnetic.

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

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

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

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

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

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

Ferralium is the world’s first super duplex stainless steel developed by Langley Alloys in 1967.

Super duplex stainless steels benefit from a combined microstructure of austenite and ferrite, which provides an optimum mix of properties.

The difference in properties between austenitic and duplex stainless steels is explained by their different microstructures.
