Ductile Iron grade 60-40-18
Categories: Metal; Ferrous Metal; Cast Iron; Alloy Cast Iron; Ductile Iron

Material Notes: Carbon represents the total carbon in the listed composition. Cerium is an optional constituent in ductile iron. Most ductile irons are specified based on mechanical properties and have loosely defined compositions. For example, 60-40-18 ductile iron is specified to have a minimum tensile strength of 60 ksi (414 MPa), a yield strength of 40 ksi (276 MPa) and an elongation of 18%. Ferritic, annealed. Applications include pressure-containing parts for use at elevated temperatures, valves and fittings for steam and chemical plant equipment.

Key Words: UNS F32800, ASTM A395-76, ASME SA395, ferritic, pressure parts
