Bending Cold Roll Sheet Steel

Cold formed steel cfs is the common term for steel products shaped by cold working processes carried out near room temperature such as rolling pressing stamping bending etc.

Bending cold roll sheet steel.

Category thickness minimum bend bend radius. The former is a process used with sheet metal. In cold rolled mild steel the minimum bend radius is 63 percent of the material thickness. 22 gauge 0 030 0 76 mm 0 5 12 7mm.

Cold rolled high carbon annealed spring steel. 22 gauge 0 030 0 76 mm. Annealed spring steel can be used for many applications which is why it makes for a great general use steel. A minimum bend radius for one material thickness is not the same for another material thickness.

003 through 250 widths in stock. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The terms are opposed to hot formed steel and hot rolled steel. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Weldability cold rolled steels can be joined using accepted welding practices. In general cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated and provides a better overall surface finish. Bend stronger by bending against during forming cold rolled steel is strongest when a bend is made against the grain weaker when bent with the grain. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

The steel is processed further in cold reduction mills where the material is cooled at room temperature followed by annealing and or tempers rolling. Cold rolled steel is essentially hot rolled steel that has had further processing. Paintability cold rolled steels due to stringent surface roughness controls are readily paintable using an appropriate paint system. Stock bars and sheets of cold rolled steel crs are commonly used in all areas of manufacturing.

Cold rolled steel cold working is a metal forming method that has many advantages over hot working. Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio. Cold rolled steels can be used to produce parts with forming ranging from simple bends to extreme deep drawing requirements. Technically cold working includes cold rolling and cold drawing.
