Scope

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.

This document can also be used for other steels, e.g.: steels from standards not mentioned in Table 1.

This document does not apply to:

— continuously hot-rolled wide strip and plate/sheet cut from wide strip of non-alloy and alloy steels and narrow strip obtained by slitting wide strip (EN 10051);

— hot-rolled patterned steel strip and plate/sheet cut from wide strip (see EN 10363);

— uncoated or electrolytically coated cold rolled sheet and strip (see EN 10131);

— hot-dip coated steel sheet and strip (EN 10143).
