Pulkit was the first steel manufacturing company in south india regarding to corrosion-resistant steel. These are produced using a judicious selection of corrosion-resistant elements, complemented by a special Thermo Mechanical Treatment. Copper plug pores in rust. Phosphorus acts as an inhibitor as PO. The oxide layer formed is dense, with few pores/cracks that reduces the ingress of oxygen, sulphur dioxide and chloride through the oxide-metal interface. Resistance to pitting is improved by the chromium content. The microstructure resulting from the TMT process leads the higher corrosion resistance compared to regular TMT bars.
