Continuing on what we saw during the past few years, the focus this year again was on improving safety, performance and design, all at the lightest weight possible for fuel economy. While there have been debates in the past about the best lightweight material, there was a clear winner at this year’s NAIAS. Almost every car, including the 2018 Car of the Year, was clad in advanced high-strength steel (AHHS) and significantly lighter than their predecessors.

Take a look at some of this year’s steel-clad cars.

2018 Car of the Year: Honda Accord

The 2018 Honda Accord took home the prestigious title of Car of the Year due to its lightweight and improved strength and performance. The 2018 model contains 29 percent ultra-high-strength steel (UHSS) in its chassis and 54.2 percent high strength steel (HSS). With these applications, the Honda Accord achieved a weight reduction of 110 to 176 pounds while improving its body torsional rigidity by 32 percent and its bending rigidity by 24 percent.

2019 Chevy Silverado

The all-new Chevy Silverado comes armed with plenty of steel. One of the features that contribute to its improved safety is the bed floor made of roll-formed HSS. Also, 80 percent of its fully-boxed steel frame is made of HSS and AHSS forms the Silverado’s safety cage. Overall, the new model is taller and 7 inches wider than before. Nevertheless, the all-new Silverado is 450 pounds lighter with a 10 percent increase in torsional rigidity than the previous model.

2019 Dodge Ram 1500

The 2019 Dodge Ram 1500 is another steel-intensive vehicle revealed at NAIAS. About 98 percent of this year’s model is made from HSS, and is the lightest, longest and most efficient frame in the half-ton truck segment. The wheelbase and crew cab is 4 inches longer than the previous model. The Dodge Ram 1500 also has several new safety features. The unique front-splayed frame rail technology, frame-mounted HSS tire blockers and fully-boxed side rails allow the car to absorb more energy in case of impact and minimize structural damage.

2019 Kia Forte

The 2019 Kia Forte is taller, wider and longer than before with 54 percent of its chassis made of AHSS. It also has a 16 percent stiffer body-in-white and the new seat frames are lighter yet stronger as Kia has its eyes on top ratings from the Insurance Institute for Highway Safety (IIHS) for the second consecutive year. The lighter and stronger vehicle will consume about 9 to 20 percent less fuel as well as drop noise levels by 5 decibels.

Why the Steel Overload?

As mentioned above, the latest cars are steel-intensive and automakers increasing the amount of HSS, UHSS and AHSS in their mix of materials. Of course, the main reason for this is steel’s innate properties that make it the ideal solution for automakers looking to cut back on weight and still satisfy safety standards. However, automakers also learned a good lesson from automakers who chose another popular lightweight material – aluminum.

Back in 2014, Ford released its F-150 with an all-aluminum body. The move was bold and the cars sold fast as it was a whole 700 pounds lighter than previous models. Consumers got to drive away with a drastically improved fuel economy, but it didn’t take long for them to realize the big, expensive problem with aluminum bodies: repairs.

Although steel and aluminum are similar in terms of its lightweight properties, aluminum reacts differently than steel under heat. Aluminum does not have metal memory, while steel does, making it hard to reshape and repair following an accident. Welding aluminum also takes much more skill and precision than steel, and there are few repair shops that are equipped to handle aluminum. As a result, drivers not only have a hard time finding repair shops for their aluminum cars, they have to pay a hefty price for repairs compared to repairs for steel cars. For example, Jalopnik reported one of the first cases of the F-150 repairs back in 2015 cost USD 17,000 and a month-long repair time.

Of course, this was a rare case highlighting the steep learning curve of repairing aluminum vehicles, but it also highlights the fact that steel is still the norm when it comes to automotive materials, and judging from the 2018 NAIAS, it’s going to stay that way for quite some time.

POSCO GIGA STEEL –  For Automakers

POSCO GIGA STEEL is like the iPhone X or the latest Xbox or PlayStation for automakers. It’s the newest, hottest must-have item for any type of car. Automakers are constantly working to lightweight their vehicles without compromising strength to meet increasingly stringent safety and environmental regulations. In order to offer its auto partners the ultimate solution, POSCO developed POSCO GIGA STEEL, an advanced high-strength steel (AHSS) that comes in 6 different types for a variety of applications in vehicles.

Applying AHSS, including POSCO GIGA STEEL, resulted in a 26 percent reduction in the total weight of a vehicle. Not only that, POSCO GIGA STEEL emits about 10 kg less carbon emissions than aluminum from a life cycle analysis (LCA) viewpoint. Plus, POSCO GIGA STEEL is about 2.1 to 3.5 times less expensive than alternative options like aluminum. It’s no surprise that leading automakers like Renault Samsung, Ssangyong Motors and GM Korea use POSCO GIGA STEEL, proving it to be the all-time favorite gift for automakers.

PosMAC- For Photovoltaic Structure Manufacturers

Solar energy is the fastest growing source of renewable energy in the world, according to the International Energy Agency (IEA). In India, solar electricity generation capacity quadrupled from 2014 to 2017 as it is the cheapest form of alternative fuel in the country. The government also plans to back the industry with USD 100 billion in investments. India is one of many countries looking to solar energy to meet their country’s environmental goals and stimulate the economy.

As a result, photovoltaic (PV) structure manufacturers around the world are working to keep up with the growing demand and gain a competitive edge with high-quality products. PosMAC is ideal for PV structures because it is highly corrosion resistant and cost-effective. Not only is the material itself lower in costs compared to other materials, PosMAC ensures a long lifecycle, decreasing maintenance costs to give manufacturers an added competitive edge. For such manufacturers, POSCO PosMAC steel is the perfect gift.

Magnesium- For Electronics Manufacturers

Magnesium is a common material in electronic devices such as laptops and smartphones. Magnesium is the perfect gift for electronics manufacturers such as LG and Samsung, as their competitiveness lies in delivering the most versatile, lightweight and convenient devices to their customers.

Magnesium is also increasingly finding its way into the automotive industry, especially for electric vehicles (EVs), as magnesium plates and other parts allow automakers to further reduce the weight of the car. Magnesium will likely be the perfect gift for that manufacturer who is thinking ahead and always experimenting new ways to improve future models of their cars.

Hyper NO- EV Manufacturers

The market for EVs is one of the fastest growing, expected to expand from USD 27.84 billion in 2016 to USD 38.98 billion by 2021, at a compound annual growth rate (CAGR) of 7 percent. Much of the success of EVs lies in its motors that will determine the EV’s efficiency, performance and feasibility for wide-spread use. As such, POSCO came up with the perfect gift for EV manufacturers – the Hyper NO.

Hyper NO is a type of electrical steel used to make electric motors. POSCO’s new technology increases the magnetic flux density and reduces core loss of electric motors, making it the perfect gift for electric motor manufacturers looking for ultimate efficiency.

Stainless Steel Products- For Everyone

There are some gifts that satisfy just about everyone, like a gift card for the movies or the nearest cafe. It’s not super special, but it’s a safe and sure choice for anyone as it is practical and functional.

Stainless steel is the ultimate gift for manufacturers as it’s one of the most widely-used materials in the world for a variety of products including surgical tools, watches, kitchenware, buildings, pipes, artistic sculptures and plenty more. It’s literally the foundation of cities and communities all over the world, and without it, the world would not have the most basic systems in place today. Moreover, stainless steel’s non-corrosive and 100 percent recyclable characteristics make it one of the best gifts for every kind of manufacturer.

No matter the type, there is a perfect gift for every manufacturer with steel. POSCO will make sure to provide even more customized and innovative solutions for its partners and continue to “keep on giving” in the new year.
