Cast irons austenitic gray

The austenitic gray irons are gray irons with additions of nickel (and in some instances copper) to produce an austenitic matrix structure similar to the 300-series stainless steels. They have a flake graphite structure and mechanical properties similar to the gray irons. The austenetic gray cast irons (often called Ni-Resist, a trademark of Inco Alloys International) 

Refer to Table 4.4 for the compatibility of Ni-Resist alloy with selected corrodents.

Gray cast irons do not have the abrupt ductile to brittle fraction transition down to -40°C as takes place in steels. Special austenitic nodular cast iron similar to the AUS 203 grade, but with a higher manganese content of about 4%, has been obtained for cryogenic purposes for temperatures down to -253°C.
