The Hole Expansion test (HET) quantifies the edge stretching capability of a sheet metal grade having a specific edge condition. Many variables affect hole expansion performance. By understanding the microstructural basis for this performance, steelmakers have been able to create new grades with better edge stretch capability.| AHSS Guidelines
Automakers face conflicting constraints when designing new body structures: With escalating concerns about human-induced green-house gases, global legislators have passed increasingly stringent vehicle emissions regulations, with even more aggressive targets planned for the coming years. Lighter weight body structures promote reduced vehicle emissions. Fuel price increases lead to greater consumer sensitivity to vehicle fuel economy. […]| AHSS Guidelines
A consortium of 35 global sheet steel producers representing 22 countries began the UltraLight Steel Auto Body (ULSAB) program in 1994 with the goal of designing a lightweight steel auto body structure that would meet existing and proposed safety and performance targets. The body-in-white (BIW) unveiled in 1998 validated the design concepts of the program, […]| AHSS Guidelines
Vehicle programs must balance performance, safety, fuel efficiency, affordability and the environment, while maintaining designs that are appealing to customers. Use of higher strength steels allows for a reduction in the sheet metal thickness and in turn vehicle mass. The increased ductility offered by Advanced High Strength Steels facilitates part consolidation also contributing to lower weight […]| AHSS Guidelines
Steel, and specifically advanced high strength steel, satisfies automotive industry requirements for safety, emissions, fuel efficiency, manufacturability, durability, and affordability. Affordability The automotive industry has adopted light-weighting as a key part of their greenhouse gas reduction strategy. This strategy, however, must be executed in an affordable manner. Key reasons to deploy advanced high strength steels […]| AHSS Guidelines

There are different ways to classify automotive steels. One is a metallurgical designation providing some process information. Common designations include lower-strength steels (interstitial-free and mild steels); conventional high strength steels, such as bake hardenable and high-strength, low-alloy steels (HSLA); and Advanced High-Strength Steels (AHSS) such as dual phase and transformation-induced plasticity steels. Additional higher strength steels include press hardening steels and steel...| AHSS Guidelines

Using Life Cycle Assessment, Mobility as a Service (MaaS) mobility solutions like WorldAutoSteel’s flaghip Steel E-Motive (SEM) program have the potential to contribute to a reduction in GHG emissions, helping to achieve these global targets and specific policy objectives.| AHSS Guidelines
Reducing the number of individual parts within an automotive body structure, through part integration, can yield further cost, weight, and sustainability benefits without compromising performance.| AHSS Guidelines
Martensitic steel grades provide a cold formed alternative to hot formed press hardening steels. Not all product shapes can be cold formed. For those shapes where forming at ambient temperatures is possible, design and process strategies must address the springback which comes with the high strength levels, as well as eliminate the risk of delayed fracture.| AHSS Guidelines
Springback correction can take many forms. The first approach is to apply an additional process that changes the elastic stresses to a less damaging form. One example is a post-stretch operation that reduces sidewall curl by changing the tensile-to-compressive elastic stress gradient through the thickness of the sidewall to all tensile elastic stresses though the thickness.| AHSS Guidelines
Evaluating sheet metal formability using computer software has been in common industrial use for more than two decades. The current sheet metal forming programs are part of the transition to virtual manufacturing that includes analysis of casting solidification and rolling at the metal production facility, welding, moulding of sheet/fiber composites, automation, and other manufacturing processes. Computer simulation of sheet metal forming is known by several terms, including computerized form...| AHSS Guidelines
AHSS products have significantly different forming characteristics and these challenge conventional mechanical and hydraulic presses. The dramatically higher strength of these new steels result in higher forming loads and increased springback.| AHSS Guidelines
