Central Wire manufactures bars up to 0.750 inches (19.05 mm) to your specifications for parameters such as tensile strength, Rockwell hardness, diameter tolerance, and length. Material is usually supplied to 12 foot (3.65 m) random lengths. When required, bars are supplied centerless ground to meet high custom tolerances.
Bar Stock Applications
Hot Heading &
Warm Heading
Our customers can hot head or forge any material grade we supply, including stainless steel. Hot heading a bolt (generally known as hot forging when on a vertical press) entails heating a measured “cut off blank” from round bar in an induction coil. Then the blank is inserted into the die and the punch forms the bolt head, either in the punch, in the die or both in a single stroke or “blow”. On certain head styles, hot heading allows for better formability with fewer “die blows.”
When it comes to large quantity orders in diameters less than 1.125″, this process is both slower and more expensive than cold heading. Hot forging is better for low quantity orders because of the time and money required.
Warm heading is similar to cold heading, except with heat. The temperature applied to the alloy in warm heading is lower than it is in the hot heading process.
Fluid Power
Hydraulic cylinders, piston rod construction, bar stock manifolds with passages and holes for mounting valve systems, or simply plumbing consolidation are all examples of Fluid Power applications. Consolidating plumbing with bar stock can be extremely beneficial in terms of reducing the need for adapters and fittings. Within the fluid power industry, machining finished product is another good use for bar stock. Subplate mounts can be made by slicing bar stock into smaller pieces. Sub plates allow one valve to be installed on top of another.
