Application of Advanced High Strength Steel to NVH Components

Most applications for Dual Phase hot rolled steel have been large components like frame members that yield significant weight savings. Difficulties in secondary forming have limited the range of parts produced. One area with good potential is noise-vibration-harshness components (NVH), since such parts tend to be heavy gauge. Significant weight reduction should be possible through thinner steel without compromising design requirements, also potentially reducing cost as well. Fatigue properties of Dual Phase also match well with these applications. We have successfully produced a multi-stage deep drawn cup for an engine mount using DP590/600 from different steel sources, demonstrating this material can be used for a new group of applications.
