Types of steel used in the automotive industry
Hot-rolled and cold-rolled steel products have been the most important materials for the automotive industry over the past few decades. While meeting increasingly stringent automotive engineering requirements, GNEE steel products are also cost-effective in terms of cost, longer service life and variability in strength levels.
According to the International Organization of Automobile Manufacturers, vehicle production was 95.6 million units in 2018.
An average of 900 kilograms of hot-rolled and cold-rolled steel are used per vehicle. The use of steel in vehicles is as follows:
• 34% used in body structure, panels, doors and trunk lid to prevent high strength and energy absorption during collisions
• 23% of the powertrain consists of cast iron for the engine block and machined carbon steel for wear-resistant gears.
• 12% suspension, using high strength rolled steel strip.
• The remaining parts are found in the wheels, tires, fuel tank, steering and braking system.
GNEE is your best automotive steel supplier
The automobile manufacturing industry mainly uses cold-rolled coils for the production of automobile structural parts. Cold-rolled steel plates with a thickness of 0.5 to 1.5 mm are mainly used for car bodies. Soft non-alloy materials were favored earlier due to their high formability and design freedom. Cold-rolled steel coil is a core material for the automotive industry. Mainly used for vehicle shells and structures. GNEE's high-quality hot and cold rolled coil steel can adapt to various steel specifications, such as JIS 3112-90 DIN 17102-83. In addition to deep drawing and drawing forming, suitability for welding, joining and painting are also important criteria for processing. Higher strength steels can also meet these requirements.
Automotive Steel Product Trends
As production technology advances, new aluminum and magnesium alloys are also used more. Plastics and composites are also favored by automotive companies for their lightweight and recyclable properties.
