ASTM A1008 Cold Rolled Steel
Cold Rolled Steel is a mill product made with a high degree of gauge accuracy and uniformity of physical characteristics. Cold Rolled Steel's smooth deoxidized matte finish gives an excellent base for paint, lacquer, and enamel. Box annealing and absence of scale permit stamping and moderate drawing operations. Sheets bend flat on themselves without cracking. Oiling protects the surface against rust. Our Cold Rolled sheet and coil conform to ASTM A1008.
The application of surface oil to cold rolled steel sheets, and coils is intended to protect from corrosion ("rusting") during shipment and warehousing. Because cold-rolled steel sheets and coils are prone to rusting, the standard practice is to apply a rust-preventative oil at the exit end of the temper mill (the last processing step). Rust-preventative oils are different than forming lubricants in that they contain special corrosion-inhibiting additions. In addition to the oil, Curtis Steel maintains clean, dry environments in climate-controlled warehouses at all its facilities to ensure our coils and sheets arrive to you in prime condition.
Cold Rolled vs Hot Rolled Steel
| Feature | Cold Rolled Steel | Hot Rolled Steel |
|---|---|---|
| Rolling Temperature | Room Temperature | High Temperature |
| Strength & Hardness | Higher | Lower |
| Formability | Less Ductile | More Ductile |
| Surface Finish | Smoother | Scaly |
| Dimensional Tolerances | Tighter | Less Precise |
Cold-rolled sheet products have been available for many, many years, and have been successfully used for a multitude of applications. Today's cold rolled sheet products are much improved over those used in the past. They offer better control of thickness, shape, width, surface finish, and other special quality features that complement the emerging need for highly engineered end-use applications.
Typical Applications
Cold rolled steel sheet and coil products are used in a wide variety of end applications such as:
- Appliances
- Automobiles
- Electric motors
- Plumbing fixtures
- Drum manufacturing
- Shelving
- Furniture
- Doors
- Toolboxes
- Tubing products
- Uniform surface finish
- Tight thickness tolerances
- High degree of formability
- Outstanding shape control (flatness)
- Exposed as well as unexposed parts
Benefits
- Strength: Cold-rolled steel is 20% stronger than hot-rolled steel
- High-quality finish: Cold-rolled steel can be coated with a variety of materials, including zinc, aluminum, and paint, to improve its resistance to corrosion, wear, and weather.
- Cold-rolled steel has a tighter tolerance, meaning it can be rolled thinner by up to 50%
