Welcome To Durham Foundry A Sheffield manufacturer of Grey, Ductile and Alloy Iron Castings, specialising in the Engineering, Architectural and Decorative markets. The enameled layer protects the food from contact with the iron portion of the pan and hence, offers an option that is both practical and safe. Size in Part Number Materials A in Weight lb 2-1/2 x 1-1/2 38RT1024014D 150 lb. The oldest operating cast iron main is that at Versailles, France, installed in 1664. The examples shown. Ductile iron is an iron-carbon casting material whose matrix includes carbon in the form of nodular graphite particles. By constructing a pressure chamber with an argon atmosphere and remote controls, melts of liquid cast iron with an upper layer of liquid magnesium were produced and analyzed. Ductile cast iron (DCI) possesses several engineering and manufacturing advantages when compared with cast steels [1,2]. There are many grades of gray iron as per the ASTM A48 standard. Besides iron and carbon, this alloy contains silicon (Si), small amounts of manganese (Mn), sulfur (S), and phosphorus (P).
