Development of Hot-Rolled Sheet Steels for Auto Chassis Frames in PanGang

摘要

This paper describes the development of hot-rolled sheet steels used for auto chassis frames in PanGang. More than 20,000 tons of P510L, P440L, P420L and P370L sheets have been produced throughthe low C-Mn-V alloying together with the wire-feeding and controlled rolling techniques. These sheet steels have been successfully used in autoworks.
