Smart-Keen clearly understands that Ductile Iron is not a single material, but a family of versatile cast irons exhibiting a wide range of properties which are obtained through microstructure control. The most important and distinguishing microstructural feature of all Ductile Irons is the presence of graphite nodules which act as "crack-arresters" and give Ductile Iron ductility and toughness superior to all other cast irons, and equal to many cast and forged steels.We supply various valves parts(check valves,gate valve body,ball valve wedge,bonnet,conneting parts),pump parts(pump housing).And we also have ever produce different automotive parts(intake manifold,exhaust manifold)especially in ductile iron/nodular iron by resin sand wax investment such as:ASTM/A356 UNS 70-50-05 Ductile Iron Manhole Cover & Frame,Terra SeepASTM.A48 UNS No.45A F13301 Ductile Iron Pulley to SpainASTM/A356 UNS 65-42-12 F33100 Ductile Iron Wheel Housing to Italy ASTM/A356 UNS 60-42-10 Ductile Iron HoopASTM/A356 UNS 60-42-10 Ductile Iron to Belgium ASTM/A356 UNS 60-42-10 Ductile Iron Pulley ASTM/A356 UNS 65-45-12 Ductile Iron to FranceASTM/A356 UNS 70-50-05 Ductile Iron Valves Bonnet & Cover,locks Exported to U.S.A ASTM/A356 UNS 65-42-12 F33100 Ductile Iron Pipe Fittings,Mechanical Tee,to U.S.A scaffold fasteners
