Combining values from the two systems may result in nonconformance with the speci? The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Thus, solution annealing also can be accomplished for nonstabilized grades by taking advantage of hot rolling temperatures which always exceed solution annealing temperature requirementsmaintaining hot rolling?

Mechanical properties such as tensile strength, yield strength, elongation, and hardness shall be determined for the specimens subjected to normalized, tempered, annealed, and quenched conditions. Such testing may or may not be routinely performed by the manufacturer. For that reason, a minimum grain size adtm been required of the H grades created for optimum elevated temperature propertiesand a mandatory grain size test and a79 has been added for the non—H grades so that the information is available for those desiring to reclassify a non—H grade to H grade.
The certification shall be positively relatable to the lot of material represented.
