A super austenitic stainless steel is considered to be one with a Pitting Resistance Equivalent Number (PREN) greater than 40.
Stress corrosion cracking is a form of failure resulting from the combination of corrosive conditions and tensile stresses within an item.
Copper is non-magnetic due to its atomic structure. This article explains how copper and copper alloys behave in magnetic fields, and highlights where non-magnetic materials like Hiduron 130 are used in marine, subsea and industrial applications.
The unique patina of copper and its alloys will develop over time and protects the surface from further corrosion.
It is possible to expose austenitic stainless steels to different heat treatments, but there is no increase in strength.
The internal microstructure of austenitic stainless steels is not influenced by an external magnet, and is non-magnetic.
Austenitic stainless steels will work-harden when deformed.
A ferrous metal is one that contains iron. Therefore, stainless steels are ferrous metals as their main constituent is iron.
Under the wrong circumstances, all forms of stainless steel will corrode or rust.
The different type of microstructure between these families of alloys infers very different mechanical and physical properties.
Super duplex grades are considered magnetic on account of their mixed austenitic and ferritic microstructure.
The Pitting Resistance Equivalent Number is a helpful theoretical way of comparing the pitting corrosion resistance of various alloys.
