PROPRIETARY Hiperco 50A Heat Treatments
- A dry hydrogen atmosphere or high vacuum is recommended to minimize oxide contamination during annealing. When hydrogen is employed and the inside retort temperature is above 482°C (900°F), the entry dew point should be dryer than -51°C (-60°F) and the exit dew point should be dryer than about -40°C (-40°F).
Anneal parts at 857-871°C (1575-1600°F) for 4 hours in dry hydrogen or vacuum and cool at 139-222°C/h (250-400°F)/h until 316°C (600°F) is reached, after which any cooling rate can be employed.
Lower temperature heat treating can be utilized to achieve higher strength in Hiperco 50A at the expense of magnetic properties.
Annealed laminations can be heat-treated in an oxygen bearing atmosphere in the range of 300-500°C (600-900°F) to grow a thin oxide layer on the surfaces. This coating serves to provide an enhanced level of electrical insulation between laminations, greatly reducing eddy current effects during AC excitation. Oxide heat treatment soak times are generally less than 5 hours and can be adjusted to refine coating thickness.
