These guidelines are the leading AHSS information resource for engineers and press shop personnel. Previous versions covered metallurgy, forming, and joining. Version 5.0 also reflects new content highlighting the broader materials portfolio, advanced fabrication technologies, and optimized joining processes. Applications of the latest steels by automotive OEM and supplier plants will proliferate during the next 10 years due to mass reduction, improved safety requirements, mandated gas mileages and customer demands. Currently vehicle applications have not nearly exhausted the breadth of AHSS grades available that can achieve lightweighting targets at less cost and five to 20 times less production emissions than alternative low density materials. This rapid increase in demand requires users of AHSS to quickly accumulate both basic understanding and application knowledge. AHSS Guidelines Version 5.0 gathers that knowledge and experience in two volumes. Volume I includes metallurgy, forming and joining. Following the series of UltraLight programs* a decade ago, which influenced the growth of High-Strength Steels (HSS) and AHSS vehicle applications around the globe, WorldAutoSteel formed a special working group of expert members from major steel companies globally to create the first AHSS Guidelines. The publication explains how and why AHSS steels are different from traditional higher strength steels in terms of formability capabilities, fabrication, and joining. Over the last decade the size of each revised document increased as more knowledge was accumulated. The last document (Version 4.1) was published in June 2009. During the last five years, additional research and press shop experiences have resulted in even greater understanding of these unique steels. AHSS Guidelines Version 5.0 was created to capture this additional knowledge, as well as lessons learned from the FutureSteelVehicle (FSV) program. This update doubles the size of the previous volume, with a vast amount of new hands-on experience from the design and manufacturing of AHSS vehicle applications. Technical editors for AHSS Guidelines Version 5 are Stuart Keeler, Sc.D. Mechanical Metallurgy, who has served in this role since the first publication, and Menachem Kimchi, M.Sc.
