All carbon and alloy H-band steels are shown, along with their corresponding minimum and maximum hardenability limits, for which sufficient hardenability data have been established and for grades which use the standard end-quench test. As hardenability data are accumulated for other grades, this SAE standard will be revised to include such grades.
