PROPRIETARY VDM Alloy 825 CTP Heat Treatments

Solution annealing should be carried out at temperatures above 1010°C (1850°F). Water quenching or rapid cooling should be carried out to achieve optimum corrosion characteristics. Workpieces of less than 3 mm (0.12 in) thickness can be cooled down using air nozzles.

For strip and wire products, the heat treatment can be performed in a continuous furnace at a speed and temperature that is adapted to the material thickness.

The workpiece has to be put into the pre-heated furnace. The furnace should be heated up to the maximum annealing temperature. The retention time during annealing depends on the workpiece thickness and can be calculated as follows:
-For thicknesses d ≤ 10 mm (0.4 in) the retention time is t = d • 3 min/mm
-For thicknesses d = 10 to 20 mm (0.4 to 0.8 in) the retention time is t = 30 min + (d - 10 mm) • 2 min/mm
-For thicknesses d > 20 mm (0.8 in) the retention time is t = 50 min + (d - 20 mm) • 1 min/mm
