Introduction to Advanced High Strength Steel Applications and Manufacturing
I.D. # C1416 Duration 2 Days
Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures. In addition, key manufacturing areas including stamping and welding will be addressed to demonstrate the increased challenges as compared to lower strength steel grades. Troubleshooting of typical engineering and production problems will round out the seminar leaving attendees with tools to help design more robust engineering solutions to AHSS applications.
Learning Objectives
By attending this seminar, you will be able to:

  • Define AHSS grades and describe general properties of AHSS
  • Identify potential applications for AHSS
  • Describe key manufacturing processing issues
  • Assimilate tools for trouble shooting part issues

Who Should Attend
This course is designed for Automotive Body Engineers, Die Engineers, Designers, Manufacturing Plant Personnel, New Hires in the Steel Industry, Supervisors, Planners, and others who would like to decrease vehicle weight through the use of AHSS.
Individuals should have a basic understanding of material properties to describe metal strength and formability as well as a general knowledge of body engineering and stamping.
