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.

What is Ferralium?

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

What are super duplex stainless steels?

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

What is the difference between austenitic and duplex stainless steels?

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

What are duplex stainless steels?

Duplex, Super Duplex and Hyper Duplex have a combination of austenitic and ferritic microstructures, approximately 50:50.
