Ductile Iron grade 100-70-03
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, 100-70-03 ductile iron is specified to have a minimum tensile strength of 100 ksi (689 MPa), a yield strength of 70 ksi (483 MPa) and an elongation of 3%. Mostly pearlitic, may be normalized. Applications include high-strength gears and machine components, best combination of strength, wear resistance and response to surface hardening.
Key Words:	UNS F34800, pearlitic, high-strength gears, wear resistant, surface hardened
