ASTM A 194 Grade 2 Heat Treatments


  • Stress-relieved at a temperature of at least 538°C (1000°F) after forming or machining from bar with the following exceptions: nuts made by hot forging, nuts machined from hot-forged or hot-rolled bar, nuts machined from hot-forged/hot-rolled and cold finished (max 10% reduction in area) bar, nuts machined from cold-drawn and annealed [(min 538°C (1000°F)] bar.
    Sample nuts: The manufacturer shall also perform hardness tests on sample nuts after the following test heat treatment at 540°C (1000°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.
