Product Specification

Continuous Black Annealed Cold Rolled Steel Coil Q195 SPCC SAE1006 SAE1008

1．Product Overview

Black annealed cold rolled steel coils are low carbon cold rolled steel products processed through continuous annealing or batch annealing treatment to improve ductility, softness, and forming performance. The material is widely used for pipe manufacturing, stamping, profiling, industrial panels, and painting applications.

Compared with full hard cold rolled steel, black annealed coils provide lower hardness and better bending performance for downstream fabrication.

2．Technical Solution

• Cold rolled steel substrate is processed through annealing treatment under controlled atmosphere and temperature conditions to release internal stress generated during cold reduction.
• Continuous black annealing provides stable mechanical consistency and higher production efficiency for large-volume processing.
• Batch annealing provides controlled softness and is commonly used for applications requiring improved forming capability.
• The annealing process improves elongation performance and reduces cracking risk during bending, stamping, and roll forming.
