PROPRIETARY Altemp A-286 Alloy Heat Treatments

  • Solution treated at 899°C or 982°C depending upon properties desired. Large sections, such as plate, are generally oil quenched from the solution heat treatment. An aging treatment of 718°C for 16 hours followed by air cooling is conducted after either solution heat treatment to develop the high strength. For an even higher aged strength, solution treated material may be cold worked prior to the aging treatment. Cold working should be followed by an aging cycle at a temperature lower than 718°C if maximum strength is to be produced.
