Designed for learners in automotive manufacturing, engineering, and materials science, this course offers a comprehensive introduction to the classification, properties, and advanced uses of steel in vehicle design. Beginning with foundational knowledge of steel types and their roles in automotive structures, the course progresses to explore high-performance steel grades including IF, BH, DP, TRIP, and TWIP steels. Learners will assess material performance in real-world applications, including strength, formability, crash resistance, and weight optimization. Activities involve interpreting steel diagrams, comparing processing methods, and analyzing application scenarios across vehicle sections such as chassis, body panels, closures, and safety components. By course end, learners will be equipped to evaluate and select appropriate steel types for specific manufacturing challenges within the automotive sector.
