Sinowell Metal here based in China supply this kind of full hard cold rolled steel coils and sheets. Cold Rolled Full Hard Sheet is produced for direct use by clients for applications that do not require any formability beyond very limited bending and/or roll-forming. It is supplied directly off the cold-reduction mill without any annealing to soften the steel. Thus, the steel is highly work-hardened, and exhibits a high resistance to denting, etc., but at the same time, it exhibits only minimal ductility.

Since the product is supplied directly after cold rolling without further processing, Full Hard Cold Rolled Steel Sheet will have residual cold mill oils on the sheet surface. Also, the product, in coil form, includes off-gauge coil ends unless further processing is needed to facilitate processing through the customer’s operations.

Cold Rolled Full Hard Sheet product is provided with the surface finish produced on the cold reduction mill. This will be either a matte finish or a smooth ground finish depending on the product thickness and the mill processing parameters on the specific cold-reduction mill used to manufacture the product.

The standard practice is to provide Cold Rolled Full Hard Sheet product with the residual cold mill rolling oil on the surface. Any other customer requirement will entail special processing steps and added production cost.

The following is our typical inquiry from our clients,

1.Full hard cold rolled coil (Strips must be edge trimmed, oil free as well as rust free)
§ JIS 31471SPCC
§ Strip thickness: 0.18 mm
§ Width: 1000 mm
§ Weight of a coil: 7,000 kg max
§ Coil inside diameter: 508 mm.

2. Full hard cold rolled coil (Strips must be edge trimmed, oil free as well as rust free)
§ Strip thickness: 0.235 mm
§ Width: 1000 mm
§ Weight of a coil: 7,000 kg max
§ Coil inside diameter: 508 mm.

Special processing can be applied to full hard sheet products. These include recoiling to remove off-gauge at the coil ends and tension leveling to improve shape. Also, a rust-inhibitive oil can be applied. However, this entails an additional processing step, i.e., temper rolling, recoiling, or tension leveling. If the product is ordered tension-leveled or cropped back to gauge, a rust-inhibitive oil can be applied at the same time. This product is ordered as Cold Rolled Full Hard Processed.
