Dura-Bar 80-55-06 is a ferritic-pearlitic ductile iron that is used for continuous cast products. It offers higher strength and wear resistance when compared to Dura-Bar 65-45-12, while still possessing good machinability and surface finish. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on heat treating and machining. Filing Code: CI-71. Producer or source: Charter Dura-Bar, Inc.

55-06 and 70-02 Ductile Dura-Bar are continuously cast ductile irons with about 50 and 75% pearlitic microstructures, respectively. 55-06 has about the same tensile strength as SAE 1045 as-hot-rolled steel. Its maximum yield strength and elongation are equivalent to a eutectoid carbon steel. 70-02 Ductile Dura-Bar has somewhat greater tensile strength up to 3 diameter and considerably higher yield strength up through 10 diameter. The elongation of 70-02 is lower than that of 55-06 because of its reduced ferrite content. This datasheet provides information on composition, microstructure, and hardness. It also includes information on heat treating. Filing Code: CI-62. Producer or source: Federal Bronze Products Inc..
