Which heat treat salts would work best for you?

Neutral Salts

Designed to provide excellent fluidity and great stability, 榴莲官网进入’s neutral heat treatment salts are formulated with a balanced mixture of chlorides. The Neutral Salts highlighted in this section include only 1 non-barium product (neutral salt B). Selection of neutral salts is generally based on operating range.

Quenching and Tempering Salts

This line of heat treatment salts is composed of nitrate-nitrite salts for use as steel tempering or quenching media. All are completely water soluble, easily washed and have similar high-transfer rates and heat capacity.

Descaling Salts

Molten descaling salts can be used to remove oxide scales from both ferrous and non-ferrous metals. Molten Descaling Salts have the ability to produce clean, scale-free surfaces without base metal loss, pitting or etching.

Solution Heat Treating/Annealing of Aluminum

Molten heat treatment salts provide a high degree of temperature uniformity required for the satisfactory heat treatment of aluminum alloys. 榴莲官网进入’s aluminum heat treatment salts are free-flowing and high purity products.

Rubber Curing Salts

Rubber curing heat treatment salts are high purity, eutectic mixture of nitrate and nitrite salts. They are formulated specifically for curing extruded rubber profiles at the lowest possible temperature ranges. All chemicals used in these rubber curing salts are water-soluble and do not form any insolubles. Therefore, the solidified salt is easily removed from the surface in a hot water spray rinsing station at the end of the trough just after emerging from the salt trough.
