DP800 formability improvement in structure vehicle component 2023-36-0071
The application of local advanced steels has challenges to overcome such as stampability requirements to meet manufacturing processes. Several technological alternatives have been studied to improve sheet steel formability and this work focuses on material selection. Dual Phase 800 steel has an important performance for structural parts involved in body-in-white (BIW) to reach durability and material impact resistance. On those alternatives references the coating application to reduce the friction coefficient and makes the formability process easier to mitigate drawing stamping issues.
The study deals with DP800 formability analysis applied in automotive seats, mainly on anchorage components, searching for alternatives to a better material stampability and local availability with a lower cost. These tests approached formability simulations and FLD (Forming Limit Diagrams) to compare the imported DP800-Uncoated and the local DP800EG + Phosphate steels. Additional tests were made for mechanical and metallurgical properties classification for a complete understanding of themselves.
The results indicate a satisfactory formability for coated steels, highlighting the relevance of this concept to contribute to the competitiveness of this technology to achieve a better stamping performance and cost avoidance for automotive industry.
