The manufacture of Special steel/ Stainless steel Wire Rods involves heat treatment, forging and casting. This results in formation of scales, smut and oxides on the surface of Wire Rods. These Wire Rods are dipped in a mixture of solution of Caustic Soda and Sodium permanganate in predetermined compositions and temperature for a specific time. The Caustic- Permanganate treatment effectively removes the scales and smut and cleans the oxidized surface to produce a high quality finished product.
