Anotace
This document specifies tolerances on dimensions and shape for hot rolled uncoated narrow strip and cut lengths of non-alloy and alloy steel grades in accordance with Table 1.
It is usually produced in thickness of 0,8 mm up to and including 16 mm and generally has a rolled width less than 600 mm but is also produced in rolled widths up to and including 720 mm.
Hot-rolled narrow strip has a symmetrical thickness profile with tight crown tolerances and therefore cannot be compared to slit wide strip.
This document also applies to hot-rolled strip for cold rolling.
