Cold Rolled Steel Bar Tolerances

Width governs the tolerances both width and thickness for rectangle bars.

Cold rolled steel bar tolerances. Cold finished carbon steel bar tolerances all tolerances in inches to the minus. Up to 1 5 incl. 1018 cold roll bars have a higher tensile and yield strength compared to hot rolled bars. 1018 is a low carbon steel with good case hardening qualities.

2 width governs the tolerances for both width and thickness of flats. Stress relieved after cold finishing maximum of. More finished surfaces with closer tolerances. 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.

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 finished carbon steel bar tolerances adminchi1 2019 06 10t14 43 10 05 00. Bars are true and square with well defined edges and corners. 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.

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. Tolerances shown do not apply to bars that are annealed spheroidize annealed nor malized normalized and tempered or quenched and tempered after cold finishing. Cold rolled steel bar has a wide range of beneficial features including. Below is a chart for reference on hot rolled bar tolerances.

1018 cold rolled steel round bars have a smooth dark grey oiled surface and accurate dimensions throughout. 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. Maximum of carbon range 0 28 or less. Cold rolled steel is essentially hot rolled steel that has had further processing.

Hot rolled steel is used in situations where precise shapes and tolerances are not required. 1018 cold rolled steel round bars are an excellent candidate for most processing techniques.
