Cold Rolled Steel Bar Tolerances

Up to 1 5 incl.

Cold rolled steel bar tolerances.

More finished surfaces with closer 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. Maximum of carbon range 0 28 or less. Width governs the tolerances both width and thickness for rectangle 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. Cold finished carbon steel bar tolerances all tolerances in inches to the minus. Hot rolled steel is used in situations where precise shapes and tolerances are not required. 0 007 0 007 0 010 over 5 8 to 7 8 incl.

Tolerances hot rolled carbon and alloy bars size tolerances rounds and squares sec. Maximum of carbon range over 0 28 to 0 55 inclusive. 1018 has a wide variety of applications. Cold rolled steel is essentially hot rolled steel that has had further processing.

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. It is used for parts requiring cold forming such as crimping swaging or bending. 1018 cold roll bars conforms to astm a29 a108.

Bars are true and square with well defined edges and corners. Stress relieved after cold finishing maximum of. 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.
