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...
AHSS Application Guidelines Update Begins

Dealing with Springback: The Sidewall Curl Issue
Compensate or Countermeasure? Taking Sidewall Curling Seriously In this blog post Akshay Wankhede, Application Engineer at AutoForm, describes the causes for the springback phenomenon known as the “sidewall curl”, how its occurrence on stamped panels can be identified...
A Look at the New EU Legislation for Cars and Vans
We’ve been monitoring the evolution of vehicle legislation in the world closely, advocating for life cycle thinking to be considered for the next generation of regulations. The European Union has been actively pursuing Post 2020 regulations, looking hard at CO2...
Blanking, Shearing and Trim Operations
Advanced Hight-Strength Steels (AHSS) exhibit high work hardening rates, resulting in improved forming capabilities compared to conventional HSLA. However, the same high work hardening creates higher strength and hardness in sheared or punched edges, creating...
