Advanced High-Strength Steel Guidelines
Brief Overview of A/SP AHSS Application Guidelines Project Overview
The Auto/Steel Advanced High-Strength Application Guidelines Project is compiling detailed case studies on the development and implementation of sheet metal stamping processes that employ AHSS steel grades. The intent of these case studies is to provide AHSS part designers with direction on how to design parts for maximum manufacturability, and to provide AHSS stamping process developers with direction on how to best design die processes for these grades. While there are currently on-going A/SP projects seeking to develop best practices for stamping a variety of AHSS components, these projects will not be complete for some time. This project draws from existing AHSS stamping experience to compile insights that can be used by automotive industry engineers today.

The AHSS Application case studies below can be downloaded for additional study of how other stamping process engineers met and solved the challenges of forming these important new steel grades.

Future Generation Passenger Compartment
Future Generation Passenger Compartment – Final Report (60MB)
Date: June 2007
Committee: FGPC Committee 
Description: This engineering report presents the findings of a mass reduction study of a donor vehicle passenger compartment design while improving performance to address IIHS Side Impact Crash Event and the proposed FMVSS 2.5X Roof Strength requirements. The study concludes that with rigorous use of Advanced High-Strength Steel and efficient optimized design mass savings of 31.4 percent relative to 2004 baseline vehicles is possible.
Mass Compounding Final Report
Date: June 2007
Committee: FGPC Committee 
Description: This report defines and quantifies the mass compounding effect during vehicle design with current mass influence coefficients developed from mass data of 35 contemporary vehicles. Mass compounding considers that a mass increase in a component has a ripple effect throughout the vehicle; other components need to be resized increasing vehicle mass even more. A more encouraging view of this behavior is considering a reduction in a component mass resulting in a greater mass saving.
Mass Compounding Calculator
Date: June 2007
Committee: FGPC Committee 
Description: This Excel Spreadsheet implements the findings of the mass compounding study into a tool for estimating initial vehicle mass based on conventional vehicle baselines and calculating the additional mass savings possible from an initial mass reduction of a vehicle system(s) or component(s).

A/SP Procedures For Testing Characteristics of Automotive Sheet Steel Lubricants
Description: The purpose of this document is to specify the acceptable performance requirements for an automotive sheet metal lubricant. Lubricants include mill oils, prelubes, draw compounds, blankwashes, and dry films. The term "lubricant" used in these procedures is used to describe any product added to the sheet metal that serve the primary purposes of rust prevention, friction reduction, or sheet steel cleanliness.
