Ultra-low carbon steel and Interstitial-Free (IF) steel, primarily manufactured through the cold rolling process, are critical materials designed for a range of forming applications. These are typically classified by their deep drawability, encompassing Commercial Quality (CQ), Drawing Quality (DQ), Deep Drawing Quality (DDQ), Extra Deep Drawing Quality (EDDQ), and Super Extra Deep Drawing Quality (SEDDQ). The cold-rolled ultra-low carbon and IF steel grades produced by LY Steel exemplify this category, offering an exceptional combination of deep drawing properties, excellent weldability, and superior coating performance.
This unique set of characteristics makes these advanced high-strength steels ideally suited for the manufacturing of complex and high-precision automotive components. As a result, they are extensively used in the production of both external and internal covering parts, where demanding formability and a flawless surface finish are paramount. Their application ensures the structural integrity, safety, and aesthetic quality of modern vehicles.
