Bending Cold Roll Sheet Steel

It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Bending cold roll sheet steel.

22 gauge 0 030 0 76 mm. Weldability cold rolled steels can be joined using accepted welding practices. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The steel is processed further in cold reduction mills where the material is cooled at room temperature followed by annealing and or tempers rolling.

Category thickness minimum bend bend radius. In cold rolled mild steel the minimum bend radius is 63 percent of the material thickness. 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. Hot rolled material on the other hand doesn t have grains like cold rolled steel so its strength when bent does not vary with the grain direction.

Cold rolled steel is essentially hot rolled steel that has had further processing. 003 through 250 widths in stock. 22 gauge 0 030 0 76 mm 0 5 12 7mm. 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.

The terms are opposed to hot formed steel and hot rolled steel. Paintability cold rolled steels due to stringent surface roughness controls are readily paintable using an appropriate paint system. Technically cold working includes cold rolling and cold drawing. Cold rolled high carbon annealed spring steel.

The former is a process used with sheet metal. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Stock bars and sheets of cold rolled steel crs are commonly used in all areas of manufacturing. Annealed spring steel can be used for many applications which is why it makes for a great general use steel.

Cold rolled steels can be used to produce parts with forming ranging from simple bends to extreme deep drawing requirements. A minimum bend radius for one material thickness is not the same for another material thickness. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. 125 through 60 spring steel value add services.
