Where ellipses (…) appear in this table, there is no requirement, and analysis for the element need not be determined or reported. B It is permissible to order T2 and T12 with a sulfur content of 0.045 max. C Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material test report.
