Fermonic® 60 is a fully austenitic alloy supplied in the hot worked and annealed condition (it is also known as Nitronic® 60 – a trademark owned by AK Steel Corporation). The general corrosion resistance is between that of Alloy 304 and Alloy 316 stainless steel, whereby is it generally better than Alloy 304 in most environments but superior to Alloy 316 with respect to chloride pitting resistance. More significantly, additions of Silicon and Manganese provide superior wear, galling and fretting resistance than many other corrosion resistant alloys making it preferable for applications where there is repeated movement/sliding or frequent assembly/disassembly.
These compositional additions also provide almost double the yield strength of Alloys 304/316, and higher strength can be achieved through cold working. Importantly, it remains fully austenitic – and therefore, fully non-magnetic – even after severe cold-working, although there is no improvement in galling performance from this operation.
