Cast irons compositions, mechanical properties

The figures quoted in Table 3.41, while not authoritative in indicating upper and lower limits, give some idea of the range of analysis to be expected for each type of iron. Because of this variation in composition, cast irons are usually specified in terms of their mechanical properties rather than on an analytical basis. 

The use of FRP is convenient also in older metal constmctions, since the mechanical properties of composite materials are well suited to the stmctural features of buildings employing cast iron. The exceptional tensile strength of the fibers makes up for the low resistance of the cast iron and the corrosion resistance of both materials makes the intervention durable. The traditional techniques that rely on welding are unfavorable because fliey require flie complete disassembly of the work, along with an inevitable increase of costs and time consumption. It demonstrated, moreover, the effectiveness of flie application of FRP in improving the brittle behavior of cast iron.
