Cold Rolled Steel Bar Tolerances

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 bar tolerances.

Cold finished carbon steel bar tolerances all tolerances in inches to the minus. More finished surfaces with closer tolerances. Cold rolled steel bar has a wide range of beneficial features including. Hot rolled steel is used in situations where precise shapes and tolerances are not required.

Maximum of carbon range over 0 28 to 0 55 inclusive. 1018 is a low carbon steel with good case hardening qualities. 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. Maximum of carbon range 0 28 or less.

1018 cold roll bars have a higher tensile and yield strength compared to hot rolled bars. Below is a chart for reference on hot rolled bar tolerances. Tolerances shown do not apply to bars that are annealed spheroidize annealed nor malized normalized and tempered or quenched and tempered after cold finishing. Stress relieved after cold finishing maximum of.

2 width governs the tolerances for both width and thickness of flats. 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. 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 rolled steel is essentially hot rolled steel that has had further processing.

Up to 1 5 incl. 1018 cold rolled steel round bars have a smooth dark grey oiled surface and accurate dimensions throughout. 1018 cold rolled steel round bars are an excellent candidate for most processing techniques. 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.

Width governs the tolerances both width and thickness for rectangle bars. 0 004 alloy steel.
