Advantages and Benefits of using Cold Finished Bright Bars

Cold finished steel bars possess improved mechanical properties, greater dimensional accuracy, better surface integrity and higher machinability. These superior product qualities provide a number of significant design advantages & benefits:

1. Mechanical Properties: Cold drawing increases the hardness, yield and tensile strength, which can:

1. Serve to reduce design mass (weight)
2. Eliminate costly heat treating
3. Allow the use of a less expensive grade
4. Provide increased fatigue strength and longer service performance
5. Provide better wear and corrosion resistance
6. Better resist handling damage
7. Provide faster annealing response
8. Provide greater cross-sectional uniformity
