Datasheet: Nitronic** 50

Nitronic** 50

Nitronic 50 exhibits corrosion resistance and that is superior to type 316 Stainless Steel. It has good mechanical properties at ambient and sub-zero temperatures. Unlike other austenitic stainless steels, it does not become magnetic when cold worked or cooled to sub-zero temperatures. Nitronic 50 is therefore considered for applications in the oil & gas, offshore, chemical and marine industries.

Nitronic 50 is also known as Aquamet 2, Aquamet 22, and Temet 25.

Available in all profile options
