Hot rolled steel products and cold rolled steel products have been the most important material in the automobile industry for the past decades. While meeting increasingly stringent automotive engineering requirements, gm steel products are also cost-effective in terms of cost, longer service life and variability in strength levels. The steel product is also very suitable for correction rework.
According to the international organization of automobile manufacturers, 95.6 million vehicles were produced in 2018.
Each car uses an average of 900 kilograms of hot and cold rolled steel. The use of steel products in the vehicle is as follows:
• 34% for body structure, panels, doors and trunk covers to prevent high intensity and energy absorption during a collision
• the 23% powertrain consists of cast iron for the engine block and machined carbon steel for the wear resistant gears.
• 12% in suspension ,use high strength rolled steel strip.
• the rest is located in the wheels, tires, fuel tanks, steering and braking systems.
The automobile manufacturing industry mainly uses the cold rolled coil for the automobile structure production. Cold rolled steel plates with a thickness of 0.5 to 1.5mm are mainly used for vehicle bodies. Soft non-alloy materials were preferred earlier because of their high formability and design freedom. Cold rolled steel coil is the core material of the automobile industry. Mainly used for the shell and structure of vehicles. Huaro's high quality cold and hot rolled coil steel can be adapted to various types of steel specifications, such as jis 3112-90 DIN 17102-83. In addition to deep drawing and drawing molding, the suitability of welding, joining and painting is also an important criterion for processing. Higher strength steel products can also meet these requirements.
With the advancement in technologies of production newer alloys of aluminium and magnesium are also being used more. Plastics and composite with their lightweight and recyclable properties are also liked by the automotive companies.
