ASTM A 194 Grade 7 Heat Treatments
- It shall be uniformly reheated to the proper austenitizing temperature (a group thus reheated being known as a quenching charge) and quenched under substantially uniform conditions for each quenching charge and tempered; It shall be liquid quenched; Tempering at min 595°C (1100°F).
Sample nuts: The manufacturer shall also perform hardness tests on sample nuts after the test heat treatment at 590°C (1100°F). After completion of all production heat treatments heat the specimen nuts to the temperatures indicated below for 24h, then slow cool. Test at room temperature.
