OEM custom malleable cast iron sand casting product from China sand casting foundry. We also provide CNC machining, heat treatment, surface treatment and other custom services.
Malleable cast iron is obtained by pouring molten iron with a certain chemical composition into white blanks and then treated by annealing. Graphite in malleable cast iron is mainly flocculent and sometimes a small amount of pellets. The main matrix structure of malleable cast iron is ferrite and pearlite. According to different heat treatment conditions, malleable cast iron can be divided into graphitized annealing malleable cast iron and decarburization annealing malleable cast iron.
The normal temperature mechanical properties of malleable cast iron are close to that of nodular cast iron with the same matrix. Under low temperature conditions, the impact toughness and cutting performance of malleable cast iron are better than those of nodular cast iron. Malleable cast iron castings are widely used in construction, automobiles, tractors, agricultural machinery and other fields. Malleable iron castings are often used for casting pipe connections, construction fasteners, elbows, tees, valve bodies, wrenches, jack shells, leaf spring supports, brackets, axle housings, engine connecting rods, rocker arms, etc. The heat treatment of malleable cast iron mainly includes graphitization annealing and decarburization annealing.
