ASTM A 194 Grade 16 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 heated to a temperature range from 925 to 955°C (1700 to 1750°F) and oil quenched; Tempering at min 650°C (1200°F).
    Sample nuts: The manufacturer shall also perform hardness tests on sample nuts after the test heat treatment at 650°C (1200°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.
