DC01 black annealed coil is a low-carbon cold-rolled steel coil. After special annealing treatment, a uniform black oxide film (Fe₃O₄) is formed on the surface, which is both rust-proof and aesthetically pleasing. The material has good stamping, bending and welding properties and is suitable for processing needs such as automotive parts, home appliance housings, and hardware.

Cold Rolled Black AnnealedCRBA Coil DC01 Features
✅ High-quality low-carbon steel: C<=0.12%, excellent stamping performance, suitable for general bending and stretching processing.
✅ Black oxide surface: The oxide layer naturally formed after annealing has a certain anti-rust ability and beautiful appearance.
✅ High ductility: Elongation >=28%, suitable for complex shape stamping parts.
✅ Good welding performance: suitable for spot welding, arc welding, laser welding and other processes.
Stamping: It is recommended to use lubricants to reduce mold wear.
Welding: Suitable for spot welding, MIG/MAG welding, and the local oxide layer can be removed before welding.
Surface treatment: If spraying or electroplating is required, it is recommended to pickle and remove the black oxide film first.
Rust-proof storage: It is recommended to store in a dry environment. For long-term storage, anti-rust oil or anti-rust film should be applied.
Q: Can DC01 black rewind replace SPCC?
A: Yes, the performance of the two is similar, but DC01 is European standard and SPCC is Japanese standard. The specific choice depends on the customer's standard requirements.
Q: Does black rewind require additional anti-rust treatment?
A: No special treatment is required for short-term storage. It is recommended to apply oil or cover with anti-rust film for long-term storage.
A: Yes, each batch of goods is accompanied by EN 10130 standard material report.
