GM 980X - Potential Applications and Review

The mechanical properties of GM 980X, a unique high strength low alloy steel with formability better than that of SAE 950X steels and the strength of SAE 980X steel in the formed component, are reviewed and the microstructure which produces these properties is described. A brief comparison is made between GM 980X and other steels with similar microstructures.

The superior formability and weight saving potential of GM 980X has been demonstrated in various component trials. Some potential automotive applications are listed and a few forming trials and qualification tests to validate component strength are described.
