Austenitic cast irons are used in a variety of applications including
automotive, chemical, petrochemical, food handling, marine, power plants,
pulp and paper and fluid handling. The alloys are basically of different
compositions with varying weight percentages of nickel and other alloying
elements. These alloys are a part of national and international
specifications and come in the flake and spheroidal graphite varieties.
Alloys with supplementary additions of elements for specific application
requirements with enhanced properties have been developed as
proprietary alloys. Niresist is the name applied to those families of alloy
cast irons in which the presence of a substantial amount of nickel along
with smaller quantities of other elements like copper, chromium and
manganese has rendered the alloy, austenitic in structure. The structure
and the alloying elements make the alloy superior to plain cast irons.
