Steel and heat treatment MILD STEEL Mild steel is also called plain carbon steel. It is the most common type of steel and it price is pretty low. Its composition is around about 0.05%-0.29% carbon content. Mild steel has a relatively low tensile strength but the surface can be hardened through carburizing. It is mostly used where large amounts of steel needs to be formed eg structural steel MEDIUM CARBON STEEL Medium carbon steel has great wear resistance and is used for forged automotive

Ms Sanghamitra‚ R&D Refractory Department from TATA STEEL‚ Jamshedpur‚ gave a talk on “STEEL MAKING REFRACTORY”‚ on 12th September 2012 at 11:00 AM at Ceramic Engineering department. Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained

above complex approach actually worked‚ over these four years? What was the outlook (as of the case date) for further progress in this matter? In 1975 Chaparral Steel commissioned minimill and started production. Minimills are different from traditional integrated steel plants. In minimill an Electric Arc Furnace (EAF) is used for steel making purpose and in downstream long product is made using rolling mill. The advantage of minimill is it requires less capital investment and a good solution when
