St12 Cold Rolled Carbon Steel Coil for Automotive Radiators with 0.2-4.0mm Thickness and High Formability

This cold rolled carbon steel coil is engineered for superior performance in demanding industrial applications. The cold reduction process enhances its strength, hardness, and dimensional accuracy. It features a smooth, uniform surface finish ideal for painting or plating.

This material offers excellent formability and consistent mechanical properties, ensuring reliability in manufacturing. The product is widely used in automotive components, household appliances, construction, and various machinery parts. It represents a cost-effective and high-quality solution for precision-driven production needs.

Cold rolling occurs below the recrystallization temperature, typically understood as room temperature processing. Aluminum cold rolling is categorized into plate rolling (thickness ≥0.15mm) and foil rolling (thickness <0.15mm). European and American manufacturers primarily use 3-6 stand continuous rolling mills for cold rolling operations.

The cold rolling process eliminates common hot rolling defects like pitting and scaling, resulting in superior surface quality and finish. Cold-rolled products offer precise dimensional accuracy and can be engineered to meet specific performance requirements, including enhanced electromagnetic properties and deep drawing capabilities.
