Graphitization of grey cast iron

WebThe chemical composition of gray cast iron consists of two parts: one is the basic composition, that is, five elements: C, Si, Mn, P and S; Second, a small amount of alloy elements such as Cu, Cr, Mo, Ni, Sb, Sn, etc. are added as required. Among the five elements, the content of C and Si plays a decisive role. WebNov 1, 2000 · Sn in gray cast iron is a pearlite stabilizer. The mechanism by which Sn stabilizes pearlite is achieved by blocking diffusion of C from the matrix to graphite flakes during the eutectoid reaction. Sn additions from 0.02-0.1% have been advocated to achieve the pearlite stabilizing effect in gray cast iron.
