(Tabulated in accordance with the Unified Numbering System for Metals and Alloys (UNS), Society of Automotive Engineers, Warrendale, Pa., 1975. This reference contains the cross reference numbers for AISI, ASTM, FED, MIL SPEC, and SAE specifications. The values shown for hot-rolled (HR) and cold drawn (CD) steels are estimated minimum values which can usually be expected in the size range of 3/4 to 1-1/4 in. A minimum value is roughly several standard deviations below the arithmetic mean. The values shown for heat-treated steels are so-called typical values. A typical value is neither the mean nor the minimum. It can be obtained by careful control of the purchase specifications and the heat-treatment, together with continuous inspection and testing. The properties shown in this table are from a variety of sources and are believed to be representative. There are so many variables which affect these properties, however, that their approximate nature must be clearly recognized. Multiply strength in kpsi be 6.89 to get strength in MPa.)
