In metal processing it is used for phosphatizing and detinning applications. As a molten salt bath it is used in heat treating of metal parts in the automotive and aircraft industries and as a high temperature heat transfer medium. It is also used in the manufacture of synthetic rubbers and rubber chemicals. Due to its anti-corrosion properties Sodium Nitrite solution is also used as a heat transfer fluid in Thermal Energy Storage units for large air-conditioning or process cooling applications.
