PROPRIETARY Incoloy alloy 903 Heat Treatments

Solution treatment before age-hardening should be performed in the 815-980°C (1500-1800°F) range, depending on the product and prior condition. For optimum mechanical properties, an age-hardening treatment of 720°C (1325°F)/8h, F.C. at 56°C (100°F)/h to 620°C (1150°F)/8 h, A.C. is recommended.
