PROPRIETARY NAS 630 Heat Treatments
- Normally supplied in a solution-treated condition. However, in order to obtain the maximum mechanical properties, it is necessary to perform H900 precipitation hardening heat treatment after working. If ductility is required, we recommend using H1150 precipitation hardening heat treatment. In this case, it is possible to perform precipitation hardening heat treatment of the base material, as working is also possible after precipitation hardening.
H900 precipitation hardening: 470~490°C, air cooled.
H1150 precipitation hardening: 610~630°C, air cooled. - Annealing is achieved by heating to between 1010°C (1850°F) and 1121°C (2050°F) for 60 minutes per 25.4 mm thickness followed by water quenching. Controlled atmospheres are recommended in order to avoid excessive oxidation of the surface.
It can be stress relieved at 399°C (750°F) to 482°C (900°F) for 90 minutes with little danger of sensitization. If stress relieving is carried out above 593°C (1100°F), there is a threat of grain boundary sensitization and loss of corrosion resistance.
