Hot-dip galvanized (GI) and galvanneal (GA)-coated third generation steels have been developed and commercialized at minimum tensile strength levels at both 780 and 980 MPa. This GalvaTech Highlights presentation will discuss lessons learned in manufacturability and the importance of cultivating “Third Generation” properties outside of simple strength x elongation (MPa*%). A review of the other papers offered in the 2021 Galvatech Technical Areatitled “Challenges in Galvanizing Advanced High Strength Steels” revealed similar interesting insights into manufacturability and practical aspects of comprehensive material design. New findings, success stories, and challenges will be discussed.
Best Paper Winner Matthew M. McCosby, U.S. Steel Corp., will present highlights from his Galvatech 2021 paper "U. S. Steel 3rd Generation Steel: Customer-Friendly Chemistry, Properties, and Manufacturability Enabled by Unique Processing". Selected highlights from other Galvatech 2021 papers on recent advances in AHSS galvanizability will also be summarized.
Each session will start with the 20 minute lecture, followed by a 20 minute panel discussion. This will be followed by 10 minutes of general discussion and a short break before beginning the next session.
