Austenitic Iron Castings & NI Resist Cast Iron Durham

Austenitic Castings & Ni-Resist Cast Iron Expense. Because of the nickel content, austenitic cast iron is more expensive than grey or ductile cast iron but is usually cheaper than an equivalent alloyed steel, particularly if the cost of machining the casting is taken into account. It is far easier to machine than a nickel chrome steel.

Machining Gray Iron vs. Ductile Iron Machines

Oct 10, 2008· Gray iron has better machinability compared to ductile iron.Both feed and speeds can be higher for gray iron compared to ductile iron. I am unable to quantify the benefit,but I am certain that it will be substantial. Why is the component being down graded from ductile iron to gray iron? Chocolates,men,coffee: are somethings liked better rich!!
