Research and Progress of Hot Stamping in China

Abstract

This paper introduced the significance of hot stamping on developing lightweight technology and safety property enhancement in China Automotive industry, as well as the research status and progress and market prospect of hot stamping process, Materials and equipments. Key technology and focus of hot stamping are analyzed, direction of hot stamping further development were proposed. Hot stamping process, technology and equipments with completely independent intellectual property rights were developed surrounding energy saving, process stability, quality consistency, flexible distribution of components’ strength , high cost-effective production and so on, which is of important for development of hot stamping in China.

The Oxide Layer of 10Mn5 Medium Manganese Steel for Wear Protection in High-Temperature Friction during Hot Stamping

“…The most widely used hot-stamping steel is 22MnB5, but 22MnB5 also faces problems such as low plasticity (elongation of the industrial product below 7%) and severe oxidation [6]. To solve these problems, Dong et al [7][8][9] successfully developed the third-generation automobile medium-Mn steel and hot stamping technology. The strength of medium manganese steel parts [10][11][12] manufactured by warm forming can reach 1400 MPa and the elongation can reach 11%.…”
