EDDS

Extra Deep-Drawing Steel (EDDS)


EDDS is produced from vacuum degassed steel to achieve a very low carbon content. It is chemically stabilized with elements such as titanium and niobium (columbium) during production to combine the remaning residual amounts of carbon and nitrogen to make it "interstitial-free." Excellent uniformity and exceptional formability characterize coated and uncoated sheet of this quality. The final product is excellent for deep drawn parts in that the sheet exhibits a high resistance to thinning during drawing.

EDDS sheet is non-aging, thus coil breaks, strain lines and fluting during fabrication are not encountered.

  • Weldability – Low carbon level makes this a good welding candidate.

  • Fatigue Performance – Relatively low yield, compared to other steels, makes this grade more susceptible to fatigue than higher strength steels.

  • Denting – Relatively low yield strength, compared to other steels, may make EDDS more susceptible to denting.  For additional capabilities, please check our dent-resistant steels.

  • Applications – EDDS is used in applications where severe forming characteristics are required.  EDDS is typically found in door inners, dash panels, body side inners and floor pans with spare tire tubs.
