ASTM A 983 Grade 2 Heat Treatments

  • Heat treatment for mechanical properties shall consist of normalizing followed by tempering at a subcritical temperature, or austenitizing, liquid quenching and subcritical tempering. The minimum tempering temperature shall be 595°C (1100°F). If forgings receive thermal stress relief after completion of heat treatment, then the stress relieving temperature shall not exceed (T-30)°C ((T-50)°F), where T is the tempering temperature.
