Cold Rolled Steel Round Bar Tolerances

Below is a chart for reference on hot rolled bar tolerances.

Cold rolled steel round bar tolerances.

Steel bars 1 2 cold finished carbon bars cold finished bars are produced from special bar quality hot rolled bars by cold drawing turning or grinding or by a combination of these methods. 0 0625 to 0 3125 excl 0 001. The cold working of the bar likewise improves machinability usually rated at 76. The cross sectional area of the hot rolled bar is cold reduced resulting in accurate size smooth surface increased mechanical properties and machinability.

With one of the largest size and length capabilities in the industry we produce sizes from 0 158 4mm through 16 round and lengths up to 75. We work with nominal thicknesses so it s important to know the thickness tolerance on the material you chose in order to know if the final product will be suitable for your application. Most cold finished bars are produced by cold drawing oversize hot rolled bars through a die. Sizeinches maximum of carbon range0 28 or less maximum ofcarbon rangeover 0 28 to0.

The cold reduction of the bar results in significantly improved mechanical properties with a smooth surface finish to close tolerances. Precision shafting ground to a tolerance finer than a human hair 888 278 4682.

1018 cold rolled steel round bars are an excellent candidate for most processing techniques. 0 008 0 008 0 012 over 7 8 to 1 incl. Width governs the tolerances both width and thickness for rectangle bars. Cold finished carbon steel bar tolerances all tolerances in inches to the minus.

Specified sizes rounds or squares over under out of round or square machining allowance minimum stock removal to 5 16 included 0 005 0 005 0 008 0 016. Northlake produces and stocks a diverse range of cold finished round steel bars. 1018 cold rolled steel round bars have a smooth dark grey oiled surface and accurate dimensions throughout. Standard tolerances for cold rolled steel bar stock usually choosing material thickness is one of the first steps a designer takes when starting a project.
