Ductile Iron grade 80-55-06 - MatWeb.com
Most ductile irons are specified based on mechanical properties and have loosely defined compositions. For example, 80-55-06 ductile iron is specified to have a minimum tensile strength of 80 ksi (552 MPa), a yield strength of 55 ksi (379 MPa) and an elongation of 6%. Ferritic/pearlitic, as cast. Applications include crankshafts, gears and rollers. Hardness and machinability data provided by ...
