As the electric vehicle (EV) market expands, strategic use of materials like steel and aluminum has become critical in achieving performance, sustainability, and cost objectives. Metal processing for electric vehicles is a complex field where the selection of materials can significantly influence vehicle design and manufacturing efficiency. Both automotive aluminum and automotive steel play pivotal roles, each offering distinct advantages that can enhance or hinder a vehicle’s performance, range, and cost-effectiveness.

The Steel vs. Aluminum Debate in Metal Processing for Electric Vehicles

In the electric vehicle (EV) industry, a competition between steel and aluminum has emerged, with manufacturers weighing the pros and cons of each material for specific applications. Steel, including ultra-high-strength (UHHS) and advanced high-strength steel (AHHS), is valued for its strength and cost-effectiveness. Aluminum, on the other hand, is favored for its lightweight properties and thermal conductivity, making it ideal for battery enclosures and body panels.

As original equipment manufacturers (OEMs) and EV automakers strive to optimize their vehicles, choosing steel and aluminum becomes a strategic decision. This decision is influenced not only by the materials’ inherent properties but also by factors like supply chain management, the capabilities of steel service centers and metal processing centers, and the demands of EV infrastructure. Understanding the benefits and limitations of each material can guide manufacturers in creating electric vehicles that meet the highest performance and sustainability standards.

The Case for Steel

Advantages of Automotive Steel in Electric Vehicle Manufacturing

Automotive steel, particularly ultra-high-strength steel (UHHS) and advanced high-strength steel (AHHS), offers exceptional strength and durability, making it ideal for structural components that must withstand significant stress, such as the vehicle frame and chassis. In addition to its robustness, steel is generally more cost-effective than aluminum, making it a preferred choice for manufacturers with budget constraints. This is especially important for original equipment manufacturers (OEMs) looking to optimize production costs.

Furthermore, steel is highly recyclable, aligning with sustainability goals and reducing the carbon footprint of vehicle production. The use of galvanized steel also enhances longevity and corrosion resistance in automotive components.

Challenges of Using Steel in Electric Vehicles

One downside of using steel is its weight, as it is significantly heavier than aluminum. This added weight can negatively affect a vehicle’s overall efficiency and range, making it less ideal for electric vehicles focused on maximizing energy efficiency.

Automotive Steel Processing: AHSS and Galvanized Steel

Patton Quinn2020-05-14T15:38:03+00:00April 14th, 2020|News Blog|

Steel continues to be the frontrunner when it comes to car manufacturing because of its strong and dependable nature. According to worldsteel.org, there are several benefits of using steel in automotive production. Steel:

● Contains recycled steel and is endlessly recyclable.
● Has lower CO2 life cycle emissions than any other automotive material.
● Enables engineering of crash-resistant structures.
● Is a higher strength steel that enables lightweight vehicle construction that is stronger, safer, and more fuel-efficient
● Enables creative, flexible designs.
● Is easy to repair with existing techniques and equipment, making repairs more affordable.
● Is cost efficient compared to all other structural materials.

There are several common uses for steel in an automotive vehicle. Most of this steel is found in the skeletal body of the vehicle, often called the “body in white,” which is the foundation from which the rest of the vehicle is created.

Bumpers and Reinforcements

Bumpers are some of a vehicle’s first defenses against any major impact, thus they demand a very high level of force absorption. The durability and crash resistance of high strength steels make it a great option for bumper systems. Further driving its use is the ability to employ a thinner steel, promoting additional weight savings. UHSS bumpers are typically roll formed. For more detailed information on steel bumper systems for passenger cars and light trucks, visit this website: https://www.a-sp.org/-/media/doc/smdisteel/bumpers/smdi-steel-bumper-systems-manual-6th-edition—january-2019—final.ashx

There are many other areas of a car that need strong reinforcement. Sill reinforcements and cross-members, for instance, both require high energy absorption. Stiffness can be maintained when transitioning to thinner panels by changing the geometry of the parts. High strength steels are well suited for these forming challenges, with the reduced thickness leading to a lighter weight part.

Door Beams and Seating

Again, weight savings are a major consideration here. Side impact beams are now commonly made using the highest strength steels, leading to both increased safety and lighter weight products. While seats are not traditionally considered part of the Body-in-White, they are some of the heaviest items in a passenger vehicle. As such, they are prime candidates for lightweighting using high strength and durable steels.

Chassis and Frames

High-strength steel benefits the entire frame’s support capabilities. The chassis is subject to some of the most extreme stresses seen on any of a car’s parts, so it needs excellent fatigue resistance properties – such as those found in high-quality steel. Using high strength, high formability steels allows the vehicle designer the flexibility to create lightweight complex shapes while maintaining the structural integrity demanded by the application.

AHSS Leads the Automotive Industry in 2020

Patton Quinn2021-02-18T17:40:43+00:00January 4th, 2020|News Blog|

No one has ever walked into a car dealership and said to the salesperson: “Hey, do you have anything made out of an unstable material?” When assembling vehicles, car manufacturers face a specific challenge: they need materials with seemingly contradictory properties: lightweight, but strong, and highly formable into rigid structures. This is a challenge in light of how metals deform. The strains from forming accumulate into localized areas on the part, leading to excessive thinning known as “necking.” These areas are thinner than the rest of the part, and are the most likely to have durability or fatigue problems during the vehicle life. Higher strength materials are more likely to experience “necking” during the production process, which, in turn, creates an unstable part. Most would agree that would never be a good quality in a car.

$Four photographs of steel at different stages during the tensile test: a) uniform deformation, b) diffuse necking, c) localized necking, and d) fracture.$

The first antidote to this challenge was introduced in the 1980’s when the steel industry developed interstitial free (IF) steels. These steels have a microstructure primarily consisting of a single phase known as ferrite, which is iron with typically less than 50ppm carbon in an interstitial solid solution. It has a body-centered cubic (bcc) structure at room temperature. ULC steels are highly formable, a desirable trait for auto companies that have a high demand for steel that can be molded into the new complex shape of cars. However, these steels are relatively soft which makes them poor candidates for the automotive body structures that need to withstand increasingly stringent crash resistance requirements. Steelmakers had to create new steel grades that combine mechanical strength with high ductility (the ability to undergo significant plastic deformation before rupture). Enter advanced high strength steel!

What is AHSS?

The metallurgy and processing of advanced high strength steel (AHSS) grades are somewhat novel compared to conventional steels. Their remarkable mechanical properties are the result of their unique processing and structure. They are classified into categories based on their microstructure or how they deform: dual phase (DP) steel, transformation-induced plasticity (TRIP) steel, complex phase (CP) steel, martensitic (MS) steel, ferritic bainitic (FB) steel, and twinning-induced plasticity (TWIP) steel. AHSS solves two distinct automotive needs by using two different groups of steels. The DP and TRIP grades of steel have increased values of the work hardening exponent. These possess higher strength levels with improved formability and crash-energy absorption compared to the current HSLA (High Strength, Low Alloy) grades. The CP and MS grades extend the availability of steel in strength ranges above the HSLA grades.

Additional steels are designed to meet specific process requirements. These include increased edge stretch […]
