Dura-Bar 65-45-12X is a ductile iron that is used for the production of continuous cast products. Its microstructure consists of nodular graphite and a matrix comprising ferrite and 10–50% pearlite. The predominantly ferritic matrix of Dura-Bar 65-45-12X allows it to be easily machined as opposed to steels and pearlitic irons. Dura-Bar 65-45-12X is a suitable alternative to low and medium carbon non-alloy steels. It is appropriate for applications necessitating fatigue strength and ductility. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties. It also includes information on heat treating and machining. Filing Code: CI-88. Producer or source: Charter Dura-Bar, Inc.
