PROPRIETARY Monel alloy 400 Heat Treatments

  • The material will remain bright and free from discoloration when heated and cooled in a reducing atmosphere or quenched in an alcohol-water solution. Rate of cooling will have no significant effect. Alloy will form an adherent oxide film if allowed to cool in air after heating.
    Both cold-worked and hot-worked alloy requires thermal treatment to develop the optimum combination of strength and ductility and to minimize distortion during subsequent machining.
    Stress equalizing is done by holding for about 3 hr at a temperature of 302°C (575°F)
    Stress relieving will reduce stresses without producing a recrystallized grain structure. This treatment is recommended to obtain minimum “walking” or distortion after metal removal. Heating for 1 to 2 hr at 538-565°C(1000-1050°F) will relieve strains in either hot or cold-worked products. Stress relief 538-649°C ((1000-1200°F)/1 hr, followed by slow cooling) is strongly recommended as a precaution against stress corrosion cracking in certain environments.
    Annealing can completely soften work-hardened material. Time and temperature required depend on the amount of previous cold work. In general, alloy is annealed by the open heating method by holding at 871-982°C(1600-1800°F) for 2-10 min, whereas box annealing is done most satisfactory at 760-816°C(1400-1500°F) for 1-3 hr at temperature. Grain growth occurs when material is heated in the upper portion of the annealing temperature range.
    Fabricating: Hot Forming - The use of proper temperature during hot forming is important. The range of hot-forming temperatures is 649-1177°C (1200-2150°F). For heavy reductions, recommended metal temperature is 927-1177°C(1700-2150°F). Light reductions may be taken down to 649°C(1200°F). Working at the lower temperatures produces higher mechanical properties and smaller grain size. Prolonged soaking at hot-working temperatures is detrimental. If a delay occurs during processing, the furnace should be cut back to 1038°C (1900°F) and not brought to temperature until operations are resumed. In no case should the alloy be heated above1177°C(2150°F); permanent damage may result. Cold Forming - alloy is adaptable to virtually all methods of cold fabrication.
