PROPRIETARY Alloy 925 Heat Treatments

All material shall be melted by Electric Arc Furnace or Electric Induction Furnace and refined by Argon Oxygen Decarburisation. Further refining by Vacuum Arc Re-melting or Electro Slag Refining are allowable as a further process. Annealing shall be carried out at a temperature up to 1010°C, allowing sufficient time for full annealing to take place, followed by water quench. Ageing shall be carried out at a temperature of up to 740°C, allowing sufficient time for controlled precipitation hardening, followed by either air or water quench.
