DC06
1.0873Interstitial-free (IF) cold-rolled steel — the absolute best formability of all automotive steels. Ultra-low carbon (<0.02%) with Ti/Nb microalloying to scavenge interstitial C and N. r-value ≥2.1. Used for the most demanding deep-drawn body panels (door inners, complex fenders, quarter panels) and structural reinforcements requiring extreme formability.
