Flat-rolled products of non-alloy steel, not further worked than cold-rolled, of a width of 600 mm or more

1. Scope and Applicability

This PCR covers uncoated flat-rolled non-alloy steel at least 600 mm wide that leaves the reporting gate not further worked than cold-rolled. Coil and cut-sheet forms are included when grade, dimensions, surface, temper and delivery form are declared. Integrated steelworks and stand-alone cold rollers are supported by linking purchased intermediates to compatible upstream cradle-to-gate datasets.

Products narrower than 600 mm; alloy, stainless, silicon-electrical or high-speed steels; hot-rolled products; and clad, plated, coated or otherwise further-worked products are excluded. Downstream fabrication, use and end-of-life are outside the reference result.
