Bending Cold Roll Sheet Steel

003 through 250 widths in stock.

Bending cold roll sheet steel.

In cold rolled mild steel the minimum bend radius is 63 percent of the material thickness. Cold rolled steel is essentially hot rolled steel that has had further processing. 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.

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. 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. Stock bars and sheets of cold rolled steel crs are commonly used in all areas of manufacturing.

125 through 60 spring steel value add services. Weldability cold rolled steels can be joined using accepted welding practices. Paintability cold rolled steels due to stringent surface roughness controls are readily paintable using an appropriate paint system. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio. 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 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 high carbon annealed spring 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. 22 gauge 0 030 0 76 mm. Cold rolled steel cold working is a metal forming method that has many advantages over hot working. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Category thickness minimum bend bend radius. Cold rolled steels can be used to produce parts with forming ranging from simple bends to extreme deep drawing requirements. 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.
