Ni Resist are Irons alloyed with high percentages of Nickel and Chromium. Basically they are the iron equivalents of Stainless steel in their properties, but alas not their looks. Two basic types are available based on the type of carbon. The graphite appears as either flake, as in grey iron or spheroidal as in SG irons. The latter have greater mechanical properties than flake. Both types, because of the high Nickel, have similar properties of heat resistance and good resistance to salt water and other corrosive materials. Chromium gives the resistance to erosion. These grades are austenitic gray cast iron grades that provide good hardness, dampening, and some corrosion resistance. These grades are very brittle and cannot be welded.
