We’re updating again!  Make sure you sign up for our enews alerts so you are notified when the new version is ready for download.  And while we don’t want to put an “Under Construction” sign on this page for our website visitors until just before our launch, we do recommend that you wait just a few short weeks for the new version!  It is significantly updated based on two years of meeting with our steel members to gather all the latest and greatest!  Sign up today to make sure you are notified!  Or, email us at steel@worldautosteel.org and ask to be put on our list.

Guidelines Support Use of the Latest, Lightest Steel Technologies

Advanced High-Strength Steels Application Guidelines V5.0 combines metallurgy, forming and joining experiences from around the world

AHSS Application Guidelines

WorldAutoSteel offers the Advanced High-Strength Steels Application Guidelines (AHSS Guidelines) Version 5.0, the largest and most comprehensive update since its first publication in 2004.

WorldAutoSteel offers the AHSS Guidelines free of charge at the link below, to aid automakers and manufacturers in applying the latest in lightweight steels.

“These guidelines are the leading AHSS information resource for engineers and press shop personnel,” said George Coates, WorldAutoSteel’s project manager for Version 5.0.  “It represents the steel industry’s strong commitment to not only produce new generation steels, but to actively assist automakers in applying them.”  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 will proliferate during the next 10 years as automotive OEM’s seek to achieve improved safety and mandated gas mileage requirements for their customers. 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.  Volume II includes over 200 pages of case studies which demonstrate actual manufacturing practices.

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. Welding Engineering, who contributed a wealth of joining information to Version 5.0.

AHSS Guidelines and accompanying Case Studies can be downloaded freely in PDF format at the link below.

Note:  Because of the large amount of information coming from our members and experts around the world, we anticipate a Version 5.1 will be issued within the next year.  Please sign up for WorldAutoSteel eNews to ensure you are notified when any updates are issued.
