Annealed Steel Coil

Annealed Steel Coil | Stress-Relieved Deep Drawing Steel

Annealed steel coil is produced by subjecting cold-rolled steel coils to an annealing process, which involves heating, holding, and controlled cooling. This heat treatment eliminates internal stresses, removes work hardening effects, refines the microstructure, and enhances ductility, softness, and uniform mechanical properties. Compared with non-annealed cold-rolled steel, annealed steel coil demonstrates superior performance in forming, stamping, bending, welding, and subsequent surface treatments.

Annealed steel coils are widely applied in industries that demand high formability and excellent surface finish, including automotive manufacturing, household appliances, construction, decorative panels, and stamping components. Production is generally in compliance with ASTM, EN, JIS, and GB standards, and can be customized to different material grades (such as Q195, Q235, SPCC, DC01) and surface finishes (bright, pickled, galvanized, tin-coated, etc.).
