Process to Manufacture Hardened and Tempered Strips

Here the process begin with heating the cold rolled strip indirectly under the controlled oxygen free atmosphere at 50 degre celsius or more above the austenising temperature. The headted strip is quenched in the molten metal bath and further cooled through the constant and controlled flow of air. The strips attain fully martensitic structure at this stage and is very hard abd brittle.
