Grey Iron Castings Methodology:
Grey iron can be alloyed with small amounts of copper, molybdenum, vanadium or chrome to produce increasingly stronger irons as the alloy levels are increased. This is achieved by controlling the amount of ferrite and pearlite in the iron matrix. Ferrite is much softer that pearlite so alloys are used, along with lower levels of carbon and silicon, which will promote a pearlitic structure. These alloyed grey irons have applications where a higher tensile strength or hardness is required. These alloys also produce an iron that can respond to heat treatment although this is uncommon. The only heat treatment routinely used is either stress relieving or annealing. With the addition of nickel up to 30% and chrome at smaller levels a range of austenitic grey irons can be produced which have improved properties at elevated temperatures and in aggressive atmospheres and environments.
