Quick Temper 430 is a eutectic mixture of nitrate salts formulated for a specific range of
operating temperatures. It is basically used as a molten heat transfer salt bath.
Quick Temper 430 has a very sharp melting point and is very fluid at the operating
temperatures. The average pH of Quick Temper 430 as a new molten bath would be
approximately 6.9. Because of the initial low pH range and because the pH range can be
controlled, if required, by small additions of potassium dichromate, Quick Temper 430 is
an ideal salt bath for the heat treating of aluminum and aluminum alloys.
