Cold Rolled Steel Round Bar Tolerances

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.

Cold rolled steel round bar tolerances.

Most cold finished bars are produced by cold drawing oversize hot rolled bars through a die. 1018 cold rolled steel round bars are an excellent candidate for most processing techniques. 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. Precision shafting ground to a tolerance finer than a human hair 888 278 4682.

Width governs the tolerances both width and thickness for rectangle bars. 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. 1018 cold roll bars have a higher tensile and yield strength compared to hot rolled bars. 0 008 0 008 0 012 over 7 8 to 1 incl.

If the bar is 1 5 thick x 3 5 wide the width tolerance of 0 006 will be the tolerance for the thickness as well which is 0 006. 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.

1018 cold rolled steel round bars have a smooth dark grey oiled surface and accurate dimensions throughout. Cold finished carbon steel bar tolerances all tolerances in inches to the minus. Below is a chart for reference on hot rolled bar tolerances. 15 5 17 4 303 304 316 321 416 cold finish.

The cold reduction of the bar results in significantly improved mechanical properties with a smooth surface finish to close tolerances.
