PROPRIETARY NAS 409 Heat Treatments

Thermal processing and fabrication annealed: Annealing is achieved by heating to between 700-750 °C for 90 min per 25 mm thickness followed by an air quench.
Stress relieving: After welding is not normally required. Should this be necessary, temperatures between 200-300 °C are recommended.
Hot working: Uniform heating of the steel in the ranges 950-1050 °C. The finishing temperature should be below 750°C. Extended holding times above 1000 °C should be avoided as excessive grain growth may occur and ductility may be detrimentally affected. All hot-working operations should be followed by annealing, picking and passivating to restore the mechanical properties and corrosion resistance.
