Dent Performance of Galvanized Coated Steel Grades Used in Automotive Closure Panels

摘要

Dent performance of steels is increasingly important as the automotive industry continues to reduce vehicle mass and improve vehicle performance. Bake hardenable steels are being applied to closure panels for improved dent resistance. Closure panels require good dent performance, along with good formability to ensure ease of manufacture. This study examines dent performance of various galvanized coated steel grades used in automotive closure panels.
