Quick Temper 300 P is a mixture of nitrate and nitrite salts formulated for a specific range of operating temperatures. Quick Temper 300 P costs a little less than Quick Temper 275 P but is not a eutectic mixture and does not have a sharp melting point. Quick Temper 300 P contains a pink dye to meet the requirement for a dye containing tempering salt.
Quick Temper 300 P is chemically stable over its wide operating range of temperatures
It is only necessary to replace that which is lost through drag out.
Quick Temper 300 P operates at a wide range of temperatures – 320 to 1000°F
The salt bath, when heated, maintains its viscosity over temperature range with very little change.
The parts, when immersed in the Quick Temper 300 P salt bath, will attain the temperature of the bath faster than in oil.
All chemicals used in Quick Temper 300 P are water-soluble and do not form insoluble ones. Therefore, the solidified salt is easily removed from the work in hot water.
Chemicals incorporated into the formulation are technical grade to insure a high purity, high grade, trouble-free mixture.

DO NOT use for martempering, as Quick Temper 300 P is not as fluid as Quick Temper 275 and will not quench the parts fast enough for a martempering operation.
