Crashworthiness and Spot Weldability of Galvannealed DP800 Steel Sheet 2001-01-3094

In this study, to confirm the practical advantages and acceptability of galvannealed TS800MPa grade dual-phase steel (DP800), crashworthiness and spot weldability as important properties in practical use were investigated and compared with conventional galvannealed TS440MPa grade and microalloyed TS600MPa grade steels, which are currently used for frame parts. The results have shown that DP800 has high absorbed energy on crash tests, and has almost the same acceptable weldability as comparative steels.
