Technical Information

ADVANCED HIGH-STRENGTH STEEL GUIDELINES - The International Iron and Steel Institute (IISI) has developed a first version of information on forming and joining of Advanced High-Strength Steels (AHSS). AHSS Guidelines documents valuable information specific to automotive body-in-white applications of this steel.

ADVANCED HIGH-STRENGTH STEEL REPAIRABILITY STUDY - PHASE I  - A study highlighting the development of appropriate repair procedures for 600 MPa tensile strength (TS) dual-phase steel and a 1300 MPa TS Martensitic steel, after exposure to typical repair arc welding and flame straightening temperature cycles. Phase I outlined recommended practices for repairing components made of these advanced high-strength materials.

ADVANCED HIGH-STRENGTH STEEL REPAIRABILITY STUDY - PHASE II  - A study illustrating the repair procedures for advanced high-strength steels, such as DP 780, TRIP 600, and TRIP 780. Phase II addresses the effect of MIG repair welding on the mechanical properties of DP and TRIP steels to validate welding as a means to repair crash damage that cannot be repaired by conventional flame straightening.

CHARACTERIZATION OF FATIGUE AND CRASH PERFORMANCE OF NEW GENERATION HIGH- STRENGTH STEELS - This report highlights fatigue and high-strain rate data for a new generation of high-strength sheet steels, including Dual-Phase (DP) steels, Transformation Induced Plasticity (TRIP) steels, Bake Hardenable (BH) steels and conventional High-Strength Low Alloy (HSLA) steels.

	Light Truck Structure A study that was undertaken to demonstrate ways to optimize steel in automotive manufacturing, while cutting costs, reducing weight, creating manufacturing efficiencies and improving performance and safety.

Advanced Component Technologies

	Steel Bumper Systems Is managed by a membership consisting of North American steel producers, who participate in the Automotive Applications Committee of AISI, a number of bumper manufacturers, and representatives of the OEMs.
	Steel Wheels What do consumers want in a wheel? How can automakers utilize styled steel wheels to reduce weight and cost and increase profitability? The Wheels Task Force has worked closely with wheel trim manufacturers and car companies and conducted consumer research to answer these questions.

Innovative Partnerships

	Steel Bar and Rod Formed in 1997 in response to AISI's commitment to expand the bar and rod market for North American steel. The steel-producing companies that make up this group are divided into two task forces: 1) Automotive/Heavy Equipment, and 2) Construction/Infrastructure.
	Strategic Alliance for Steel Fuel Tanks (SASFT)An international, multi-functional group of fuel system manufacturers, users and material suppliers to encourage further development of technologies and performance of steel fuel tanks.
	The Auto/Steel Partnership (A/SP) An innovative association that includes DaimlerChrysler, Ford, General Motors and North American sheet steel producers that leverages the resources of the automotive and steel industries to pursue research projects leading to excellence in the application of sheet steels in the design and manufacture of vehicles.

JUST RELEASED!!

LIGHTWEIGHT FRONT-END STRUCTURE PHASE I: FINAL REPORT - A purely analytical, parametric study of automotive front end design sensitivities, sponsored and overseen by the Auto/Steel Partnership (A/SP). The project, utilizing math data from the original UltraLight Steel Auto Body (ULSAB) initiative, was organized into a series of independent, and selectively discrete activities, which together formed the basis of an integrated strategy for further development of a lightweight front end structure utilizing advanced high strength steels (AHSS). The various methodologies employed included: Design of Experiments (DoE), Response Surface Modeling (RSM) and Computer Aided Optimization (CAO).

The Final Report provides detailed information about the various elements of the Lightweight Front End Structure project.
