Manufacturing Process of Cast Iron Castings

Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape.

Cast Iron: Properties, Processing and Applications - Matmatch

Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.

Hard Chroming cast iron - Practical Machinist

Feb 01, 2017· From what I understand, hard chrome is just "thick" chrome, nothing special about it. Then a typical part, say a chrome bumper is just nickel plating with a layer of chrome to prevent oxidation of the nickel. And I believe cast iron is not as easy to plate as mild steel; while a good plating job would call for a substrate of copper.
