... of alloying additions in the low-alloy gray irons is usually less than 2.0%. High-alloy gray irons contain more than 4% total alloy content and include austenitic nickel-alloyed gray irons and high-silicon gray irons. These more highly alloyed cast irons are used for corrosion-resistant and/or heat-resistant...
