What is it?
Extra-Deep-Drawing Steel (EDDS or EDDQ) describes steel that incorporates titanium and/or columbium to bind hardening elements to create an extremely refined grain pattern, and a extremely formable steel. As such, EDDS is the most formable steel grade available and exhibits a high resistance to thinning during the drawing process. As with DS Type B and DDS steel, EDDS is a good candidate for welding, suffers from low yield, and is susceptible to denting.
EDDS is used for making products that require significant forming. It is usually found in door inners, dash panels, body side inners, and floor pans.
