Automobile structure steel or automotive steel is used to provide greater strength to vehicle components. High strength of steel can be achieved by mixing alloy materials and cooling at low temperature. Additionally, automotive structural steel has excellent cold forming ability. Therefore, it is used in the making of boom, arms of truck, and trailer frames. Approximately, 34% automotive structural steel is used for body structures, panels, doors, and trunk closures, 23% automotive structural steel is used for drive train components, engine component, and gears, 12% is used for suspension units, and the remaining is used for tyres, wheels, steering, breaking system, and fuel tanks. Ultra-high strength steel is keenly used in the making of B-pillar and front cross parts of automotive vehicles. High-strength steel has good balance of strength, formability, energy absorption, and durability. Therefore, it is used in the making of roof and side panels of automotive vehicles.
Automotive structural steel makers are deliberately using lightweight alloy materials with automotive structural steel in a bid to inches physical property of vehicle components i.e., strength, ductility, toughness and fatigue and make a significant cornerstone among the customers, clientele, and in the global automotive structural steel market.
