SAE International has released a new book entitled “Automotive Lightweighting Using Advanced High-Strength Steels.” The book explores the role of advanced high-strength steels (AHSS) in addressing the challenge of vehicle lightweighting.
Advanced high-strength steels (AHSS) are a family of steels that are stronger than most steels and have better formability than today’s conventional high-strength steels. They are now a more viable alternative, as more OEMs look for the ideal combination between safety, weight and materials characteristics.
The book is intended to help design engineers make informed decisions on what basic materials to use and how to optimize them to achieve cost-effective weight reduction and, consequently, fuel efficiency. The emphasis of “Automotive Lightweighting Using Advanced High-Strength Steels” is on steels in general and AHSS in particular. However, there is much information on comparisons of steel with alternative materials for different subsystems of the vehicle.
Authored by Paul E. Geck, this new SAE International title focuses on body and chassis structures, and the sheet metal of which these systems are primarily made. More of the content addresses the automotive body, as this is where most of the AHSS are being applied today. The past, present, and future of AHSS are covered, as well as competing technologies such as aluminum sheet metal.
