(ASTM A366) Cold Rolled Steel Sheets are rolled to a close thickness tolerance and possess a fine, smooth surface providing a excellent base for painting Cold rolling is used to further treat hot rolled steel to increase its strength and its strength-to-weight ratio and enable it to hold tighter tolerances during fabricating and machining. In addition, cold rolling is used to smooth and finish the surface of hot rolled steel. The processes used to improve the surface finish and to size the steel sheet more precisely include chemical or mechanical descaling and cold rolling or polishing. CRS Steel Sheets are easy to weld, form, drill. Popular uses for CRS Steel Sheet include: automotive panels, tool boxes, hoppers, drip pans, fuel tanks, trailer siding & roofing, etc. Magnetic, Brinell = 97, Tensile = 50,000, Yield = 35,000 (+/-)
When the protective oxide surface normally found on hot rolled sheets is removed during cold rolling, it leaves a surface finish that is considered perishable. Great care must be taken during handling, storage, and shipment to preserve and protect this smooth, slick, surface.
Cold rolled steel is used for engineered products that require tight tolerances and coated surfaces. These include:Appliances, including stoves, ovens, refrigerators, washers, dryers and small appliances. Exposed automotive and aircraft components, Building frames, Deep-drawn shells, Stamped parts.
ASTM A1008 CS TYPE B SHEET Characteristics and Applications
ASTM A1008 CS Type B sheet is a cold rolled low carbon, high-strength steel-alloy sheet with improved formability. It is manufactured by annealing and temper rolling hot rolled steel sheets to provide formability, surface texture and flatness. The surface is matte finish and is oiled to prevent rust, allowing for use in exposed applications.A1008 CS Type B sheet, which is used for the following products: Appliances, Exterior automotive components, Stamped parts, Drawn parts such as furniture components, Shelving, Signs.
