EMJ sells Dura-Bar brand 65-45-12 ductile iron * A medium-high strength gray iron was selected for comparison purposes. Short Summary of Ductile Iron Specifications ASTM Specification A897-90 / A897M-90 For Austempered Ductile Iron; Grade Min. Tensile Strength. Min. Yield Gray Iron Gray Iron Grade Comparison Dura-BarDura-Bar G2P is a highly pearlitic gray iron containing Type A graphite. It was developed to best suit surface-hardenability applications. G2P is made with a substantial amount of pearlite in the rim. This requires the least amount of stock removal necessary, in order to achieve a heat-treatable surface.
