MACHINED COMPONENT CLEANING

Machined castings can be treated with no ill effect by the process because Sodium Hydride does not attack the metal. It only reduces the scale,rust, sand or any other contaminant present. Parts should be de-greased and where possible all additional components removed.

With aluminium castings it should be noted that the process temperature range of 350-370°C will spoil any heat treatment.
