Bar, Cold-Finished

One of two cold processes for producing finished bar. Cold-finished bars are designated as such to differentiate them from cold-drawn product. Cold-finished bars may be rough-turned to remove scale and improve dimensional properties. Further processing by grinding or polishing will produce exacting dimensions and a better surface finish. This adds value to the product but does not change the tensile or yield strength of the material. These types of bars are typically used for machine shafts or applications where additional surface preparation permit, such as hydraulic cylinders.
