High tensile wires are those which can withstand great strain without breaking or becoming deformed. High tensile wire is made with higher carbon steel. The increased carbon content increases the wire’s strength and elongation. As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels wire, the higher carbon content lowers the melting point. It has high strength, adequate ductility, Bendability, which is required at the harping points and near the anchorage, low relaxation to reduce losses and minimum corrosion.
High tensile wire for pre-stresses in concrete structure by virtue of improved proportional limit, higher ductility combines with higher strengths. High Tensile Wires are used in Pre-stressed Concrete Industry, large bridges, Flyovers, Ports and Road Dividers.
High tensile wire improves the bond strength between pre-stressed steel wire and concrete. Reduces the frictional losses between pre-stressed wire and concrete and increases the anchorage efficiency.
Under the dispensations of the government's Industrial Policy of the post-liberalisation era, four steps changed the direction of the steel industry in India. These were (i) freedom to set up integrated steel plants in the private sector; (ii) placing imports of steel under OGL (open general licence); (iii) reduction of import duties on both steel and scrap; and (iv) decontrol of domestic prices. As a result, India has come to enjoy a cost advantage compared to most countries. The domestic demand is based on the per capita consumption in the urban sector increasing from 77 kg to 165 kg in 2019-20 at an annual growth of 5%. As a whole it is a good project for new entrepreneurs to invest.
