Cold Finished Triangle Steel – Cold Drawn/Rolled
Cold Finished Triangle Steel – Cold DrawnRolled
Cold Finished Triangle, Cold Drawn Steel (CDS) and Cold Roll Steel (CRS) Bar is a steel product with closer dimensional accuracy, tolerances, and smoother surface finish than hot rolled bar. Cold finished steel triangle tend to have higher tensile and yield strength, tighter size tolerances, and improved smoothness when compared to hot finished steel.
These standard shapes can be produced as bar or wire in a wide variety of steel grades including: Carbon Steel, Alloy Steel, Tool Steel, High Speed Steel and Stainless Steel. In addition, these standard shapes can be supplied in custom sizes with special tolerances, finishes and mechanical properties. Precision Kidd can surface improve many of these products to provide elevated surface qualities, such as: “Seam Free” and “Decarb Free,” as well as NDT tested for surface discontinuities.
TYPICAL OPERATIONS AND APPLICATIONS USING COLD FINISHED BARS
The below are a few of the many applications using cold drawn bars for their raw material:
Screw machines
CNC lathes
CNC mills
Rotary transfer machining
Hydraulic fittings
Gears
Bushings
Fasteners
Cylinders
Pipe fitting
