Upgraded Tool Steels for Upgraded Sheet Metal Forming
We thank Dennis McPike, Zapp Tooling Alloys, Inc., for contributing this case study. Multi-phase steels are complex to cut and form, requiring specific tooling materials. The tooling alloys which have been used for decades, such as D2, A2 or S7, are reaching...
Roll Forming AHSS
Roll Forming takes a flat sheet or strip and feeds it longitudinally through a mill containing several successive paired roller dies, each of which incrementally bend the strip into the desired final shape. The incremental approach can minimize strain localization and...
Geometric Analysis of Sections – GAS2.0
A New Software Application for Thin Wall Section Analysis Advanced High-Strength Steel (AHSS) grades offer increased performance in yield and tensile strength. However, to fully utilize this increased strength, automotive beam sections must be designed carefully to...
Inventing the First AHSS Road Bike
An inspiring story You are most likely wondering why WorldAutoSteel is writing a blog about a bicycle. It is because when we talked to Jia-Uei Chan, Regional Business Development at our member company, thyssenkrupp Steel Europe (TKSe), about the journey of inventing...
Estimating Lightweighting Benefits with New Powertrain Models
Dr. Donald Malen, College of Engineering, University of Michigan, reviews the use of two recently developed Powertrain Models, which he co-authored with Dr. Roland Geyer, University of California, Bren School of Environmental Science. The Need For The Powertrain...

Understanding LME Controlling LME Preventing LME Related Articles Journal Publications Download the Study (opens worldautosteel.org website in a new tab) top-of-page Results of a Three-Year LME Study WorldAutoSteel releases today the results of a three-year study on...
Improving Joint Performance
In static or dynamic conditions, the spot weld strength of Advanced High-Strength Steels (AHSS) may be considered as a limiting factor. One solution to improve resistance spot weld strength is to add a high-strength adhesive to the weld. Figure 1 illustrates the...
AHSS Corrosion Resistant Coatings
Many steel parts on a vehicle require corrosion protection, regardless of whether they are exposed or unexposed applications. The most common way to accomplish corrosion protection is to coat Advanced High-Strength Steels (AHSS) with zinc by means of a couple of...
AHSS Fundamentals in Forming and Joining
In this edition of AHSS Insights, George Coates and Menachem Kimchi get back to basics with important fundamentals in forming and joining AHSS. As the global steel industry continues its development of Advanced High-Strength Steels (AHSS), including 3rd Gen products...
Emerging Methods Enable AHSS Forming: Active Binder Force Control
Happy New Year! We are pleased to provide this contribution by Dr. Daniel Schaeffler, President, Engineering Quality Solutions, Inc. and Technical Editor, AHSS Applications Guidelines. Forty years ago, the metal forming community needed to figure out how to stamp a...
Battery Electric Vehicles – Boom or Bust for AHSS?
Article contributed by Harry Singh, Senior Product Applications Engineer, United States Steel Corporation. Several recent studies are forecasting that; “Within the next 10 to 15 years, urban transportation will be dominated by Electric and Automated vehicles”.1...
Welding Simulation for AHSS: LME During Resistance Spot Welding
We once again welcome Max Biegler, Research Associate, Fraunhofer IPK, in this follow up article on Modelling Resistance Spot Welding. Modern car bodies today are made of increasing volumes of Advanced High-Strength Steels (AHSS), the superb performance of which...
