Cold rolled steel bar tolerances.

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. 0 005 0 005 0 008 over 5 16 to 7 16 incl. Tolerances hot rolled carbon and alloy bars size tolerances rounds and squares sec. Cold rolled steel bar has a wide range of beneficial features including.

0 007 0 007 0 010 over 5 8 to 7 8 incl. 1018 has a wide variety of applications. Hot rolled steel is used in situations where precise shapes and tolerances are not required. More finished surfaces with closer tolerances.

It is used for parts requiring cold forming such as crimping swaging or bending. Bars are true and square with well defined edges and corners. 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. 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.

1018 cold roll bars conforms to astm a29 a108. 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. Cold finished carbon steel bar tolerances all tolerances in inches to the minus. Width governs the tolerances both width and thickness for rectangle bars.

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.
