Cold finish bars with improved physical attributes are perfect for a wide range of rigid applications in automotive, hydraulic pumps, chemical processing, etc.
Cold finish bars have more improved straightness, tolerance, and concentricity. These bars are typically used for the manufacturing of bearings, shafts, fasteners, oil pump shafts, concrete accessories, hand tools, vehicle axles, and wheel spindles.
Cold finish steel bars are product of cold finishing which consists cold drawing, grinding, and polishing – which results in a higher yield points.
This process gives cold-finished bars many advantages like:
- Bright new surface finish
- Improved concentricity, tolerance, and straightness as well as close dimensions and roundness
- Enable cold-drawing [which increases tensile and yield strength and eliminate costly thermal treatments]
- Machinability improved up to 20% [which increases tool life, improves cutting speed and surface finish]
Cold finished steel bar usually have a smoother grey finish. Their final rolling is done as soon as steel is cold or in room temperature. The operation is bathed in oil to make sure bars are unoxidized and retain grey color in actual steel. Rollers smoothly do the job.
There can be only few available shapes formed when steels are cold-finished. Steel is such a very tough material to machine when it is “cold”. When steels are bent, hammered, and deformed in their “room temperature”, they may actually harden in distortion and may crack or weaken. To form the desired shape, steels have to be heated past a specific temperature in order for them to be easily bent, formed, and squeezed with ease without damaging the material.
Cold-finished bars can also be chemically colored and patinated. Since cold-finished steels don’t have oxidation on their surface, they can be best for base metal fabrication which will eventually have a secondary coloring process. Additionally, what makes cold-finished bars have an aesthetic craftsmanship is their sharp and accurate tolerance and profile.
We’ve been making and supplying cold-finished bars precisely for our customers across the MidWest. Our bars are manufactured with adherence to standards and quality – with regard to right shape and size. We provide cold-finished steels with special finishes, elevated qualities, special finishes, and exacting tolerance.
