Low and Ultra-low Carbon Steel Automotive steel
Specification
Low and Ultra-low Carbon Steel Automotive steel can be divided into common quality (CQ), drawing quality (DQ), and deep drawing quality (DDQ). It can also include extra-deep drawing quality (EDDQ) and supreme extra-deep drawing quality (SEDDQ). The cold rolled low carbon steel plates have excellent drawing and welding performance and relatively high dimensional accuracy. In particular interstitial free steel [IF steel]. It has the high value r, value n and percent elongation. Therefore, people often use it to manufacture very hard parts. For example, the inner door panel, trunk lid, and crankcase oil pan.
