Some applications don't require the tolerances or uniform characteristics of "fully-processed" cold rolled strip. Once reviewed by a metallurgist, processing might be limited to only those operations required to successfully make the application, allowing us to provide cost savings. The following detail provides broad characteristics for each type of flat-rolled strip product: Grades: All Grades - Low Carbon, HSLA, High Carbon and Alloy Processes: Full Cold Reduction, Annealed, Temper Passed, Slit/Shear Properties: Lowest Hardness, Highest Accuracy and Consistency of Surface Finish, Dimensional and Physical Properties Grades: Typically Low Carbon and HSLA Processes: Intermediate Rolled to Meet Hardness Specifications, Slit Properties: Intermediate Hardness, Accuracy and Consistency depends on the amount of Reduction taken to maintain hardness Grades: Typically High Carbon and Alloy Processes: Intermediate Rolled to Meet Gauge Tolerances, Annealed Properties: Moderately Low Hardness, Moderately High Spheroidization, Good Thickness tolerances, Moderate Surface Improvement Grades: All Grades - Low Carbon, HSLA, High Carbon and Alloy Processes: Lightly Rolled to Improve Thickness Tolerances, Slit Properties: Moderately Soft due to Rolling depending on grade and reduction, Good Thickness tolerances, Minimal Surface Improvement Grades: Typically High Carbon, Alloy and Low Carbon Processes: Annealed, Slit Properties: Moderately Low Hardness, Improved Spheroidization, No Change to the Original Surface and Thickness Tolerances or Variation
