Over the past two decades, auto manufacturers have relied on lighter metals and non-metallic materials to improve fuel efficiency and decrease weight in automobiles. However, steel is making a comeback. Several vehicles debuted in 2018 that sprung from manufacturing processes employing the use of advanced high-strength steel (AHSS).
These vehicles deserve a moment in the spotlight for the work that went into creating them.
SUV, CUV, and truck manufacturers alike saw the opportunities afforded by the utilization of AHSS and went on to create truly impressive automobiles. The companies utilizing these methods and the role that steel played in their manufacturing shouldn’t be overlooked.
Notable Models Relying on Steel in 2019
2019 Ram 1500
The steel framework of the 2019 Dodge Ram 1500 – 98% of which is high-strength steel – makes its mark for strength, durability, and efficiency in the modern truck. Not only does this offer increased durability, superior impact resistance, and protection against other unforeseen surprises, but it houses a powerful V8 engine. Through the combined work of a powerful engine and of AHSS, the Ram 1500 boats a payload capacity of up to 2,300 pounds — that’s a lot of power.
2019 Chevrolet Silverado
Chevy’s 2019 Silverado was designed with power in mind. The company isolated the hardest-working part of the truck – the bed – and sought to redesign it with innovation in mind. Thanks to high-strength roll-formed steel, the bed is now lighter, larger, and stronger while offering more cargo volume than its competition. The 2019 Silverado also features an internal AHSS safety cage surrounding the cab.
2019 Hyundai Santa Fe
A combination of high-strength steel and adhesives are responsible for the 2019 Hyundai Santa Fe’s rigid body. The vehicle comprises 67% high-strength steel – a significant step up from the 53% figure that goes into a similar model, the Santa Fe Sport. AHSS contributes to the Santa Fe’s improved crash safety and ride quality.
2019 Kia Forte
Kia came to the public with a bold statement – they were looking to "strengthen the bones” of their third generation Kia Forte. By utilizing AHSS, Kira increased rigidity, quieted the cabin, and improved handling for drivers. The car’s body is made up of 54% high-strength steel and gives drivers peace of mind thanks to the increased protection provided by these materials.
Steel & The Automotive Industry
Steel has long seen prominent use in the manufacturing of automobiles. As the industry moves to keep up with ever-shifting consumer expectations, safety regulations, and Corporate Average Fuel Economy requirements, the use of steel within the sector is predicted to grow considerably.
Advanced High-Strength Steel (AHSS)
The use of AHSS-grade steel in the automobile industry is growing more quickly than aluminum or plastic. Car manufacturers are constantly on the hunt for ways to offer lighter, stronger cars and have discovered what can be achieved through using lighter, stronger steel.
The use of AHSS in the automotive industry allows automakers to give consumers what they want and help the environment while they do it. Studies have indicated that if AHSS were applied throughout vehicles nationwide, greenhouse gas emissions from automobiles would experience a reduction of 12%.
Cold-Formed Steels
The automotive industry relies heavily on cold-formed steels for a number of vehicle components. Cold-rolled steels are used in elements like exhaust, boss mounts, and door hinges.
Cold-drawn steels, which are pulled through dies at room temperature during the forming process, typically include components involved with fuel injection or for exhaust systems. In some cases, they’re also utilized in seats and one-way clutches.
Steel is a critical part of manufacturing automobiles, but the opportunities afforded by newer AHSS-grade steels are limitless. Cars can now be made lighter, faster, and safer by integrating these innovative new material options.
