Steel Your Strength

Steel strength, the backbone of the automotive industry

Watch the SteelYourStrength video to hear automakers, academics and steelmakers talk about AHSS’s role in vehicle design.

WorldAutoSteel has published the second video of their SteelYourWorld series, that is meant to inspire audiences on the benefits of Advanced High-Strength Steels for automotive. A video has been produced on each of four topics:  Steel Your Weight, Steel Your Future, Steel Your Strength and Steel Your Environment

This video is called "Steel Your Strength" and includes testimonials from OEMs, academics and steel members on the merits of the strength of  AHSS for automotive.  There are some great quotes about our material in it.

 

 

 

Thinner, stronger, safer

For decades, the steel industry has pioneered a whole new class of materials that are 50% stronger than their predecessors. At the core of this innovation lies the ever-growing Advanced High-Strength Steel (AHSS) family. No other automotive material compares to the variety of steel strength levels today.

This means that the steel can be made thinner, yet retain its strength for vehicle structure performance and safety. Thinner material means less material is used, and therefore components are lighter, contributing to vehicle weight reduction and reduced environmental emissions. Because primary manufacture of steel produces fewer emissions than any other automotive material, it’s a win-win, both in terms of reduced steel manufacturing and vehicle emissions.

These AHSS capabilities result from their unique combination of strength and ductility. AHSS are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes. Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties.

Here are some quotes from the video

How carmakers use AHSS

Carmakers focus on improving safety, performance, cost and design, all at the lightest weight possible for fuel economy. While there have been debates in the past about the best lightweight material, advanced high strength steel is still on top. Almost every new car that is presented features advanced high strength steel (AHHS) and is significantly lighter than its predecessor.
Here are brief summaries about a few of them. 

  • The 2018 Honda Accord, winner of the 2018 Car of the Year, body structure is lighter and more rigid, utilizing 29 percent Ultra High-strength steel, the most extensive application of this weight-saving material in any current mass-produced Honda car. Overall, the new Accord employs 54.2 percent High-Strength Steel (above 440 MPa).

  • The structure of the 2019 Kia Forte redesign includes 54% Advanced High Strength Steel (AHSS), improving safety and increasing torsional rigidity by 16%.

  • The strength of steel is found in the 2017 Jeep Compass, which includes a “safety cage” construction with more than 65 percent high-strength steel.
