Cold Rolled Steel Bar Tolerances

1018 is a low carbon steel with good case hardening qualities.

Cold rolled steel bar tolerances.

1018 cold roll bars have a higher tensile and yield strength compared to hot rolled bars. Bars are true and square with well defined edges and corners. Maximum of carbon range over 0 28 to 0 55 inclusive. Tolerances shown do not apply to bars that are annealed spheroidize annealed nor malized normalized and tempered or quenched and tempered after cold finishing.

Hot rolled steel is used in situations where precise shapes and tolerances are not required. 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. 1018 cold rolled steel round bars have a smooth dark grey oiled surface and accurate dimensions throughout. 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 rolled steel is essentially hot rolled steel that has had further processing. 1018 cold rolled steel round bars are an excellent candidate for most processing techniques. Up to 1 5 incl. Cold finished carbon steel bar tolerances adminchi1 2019 06 10t14 43 10 05 00.

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. 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. Below is a chart for reference on hot rolled bar tolerances. 2 width governs the tolerances for both width and thickness of flats.

Maximum of carbon range 0 28 or less. Stress relieved after cold finishing maximum of. Width governs the tolerances both width and thickness for rectangle bars. Cold rolled steel bar has a wide range of beneficial features including.

Cold finished carbon steel bar tolerances all tolerances in inches to the minus. 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.
