1020 S20C C20 1.0402 Cold Drawn Spline Profile Carbon Steel Bar


Our profiles range in cross sectional areas that fit within a 0.032" to 2.000" diameter circle. Depending upon the profile cross sectional area, profile configuration and customer requirements, we deliver these profiles in a wide variety of forms that include catch weight and pancake wound coils, exact length and random mill length bars, deburred and non-deburred saw cut pieces, as well as adiabatic sheared pieces for larger volume requirements. Precision cold drawing controls allow us to offer linear dimensional tolerances that range from our standard +/- 0.002" to an optional +/- 0.0005". For cold rolled profiles we offer standard dimensional tolerances of +/- 0.002 on thickness and +/- 0.005" on width.
