Cold Rolled Steel Bar Tolerances

More finished surfaces with closer tolerances.

Cold rolled steel bar tolerances. Width governs the tolerances both width and thickness for rectangle bars. C1018 cold finished flat aka crs flat or cold roll flat bar is a steel product with closer dimensional accuracy tolerances and smoother surface finish than hot rolled bar c1018 cold finish flat is a general purpose low carbon steel with good case hardening qualities and is especially suited for cold forming and bending. Cold finished carbon steel bar tolerances adminchi1 2019 06 10t14 43 10 05 00. 1018 cold roll bars have a higher tensile and yield strength compared to hot rolled bars.

Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and i beams for example. 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. 2 width governs the tolerances for both width and thickness of flats. Hot rolled steel is used in situations where precise shapes and tolerances are not required.

Bars are true and square with well defined edges and corners. Maximum of carbon range over 0 28 to 0 55 inclusive. 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. Cold finished carbon steel bar tolerances all tolerances in inches to the minus.

Cold rolled steel bar has a wide range of beneficial features including. 1018 cold rolled steel round bars are an excellent candidate for most processing techniques. 1018 is a low carbon steel with good case hardening qualities. 0 004 alloy steel.

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. Cold rolled steel is essentially hot rolled steel that has had further processing. Maximum of carbon range 0 28 or less. Below is a chart for reference on hot rolled 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. Tolerances shown do not apply to bars that are annealed spheroidize annealed nor malized normalized and tempered or quenched and tempered after cold finishing.
