3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
hot-rolled steel sheet
product obtained by rolling heated steel through a continuous hot strip mill or another hot-rolling process that produces a coiled product to the required sheet thickness and tolerances
3.2 hot-rolled descaled steel sheet
hot-rolled steel sheet from which oxide or scale has been removed, commonly by pickling in an acid solution or by mechanical means such as grit blasting
NOTE 1 Some change in poper1ies can result from descaling.
NOTE 2 Descaling can also be performed by appropriate mechanical means.
3.3 skin pass
light cold-rolling of hot-rolled steel sheet or hot-rolled descaled steel
NOTE The purpose of the skin pass is to produce a higher degree of surface smoothness and thereby improve the surface appearance. The skin pass also temporarily minimizes the occurrence of a surface condition known as stretcher strain (Luders Lines) or fluting during the fabrication of finished parts. The skin pass also controls and improves flatness. Some increase in hardness and loss of ductility will result from skin passing.
3.4 mill edge
normal side edge without any definite contour produced in hot rolling, possibly containing some irregularities such as cracked or torn edges or thin (feathered) edges
3.5 sheared edge
normal edge obtained by shearing, slitting or trimming a mill edge product
NOTE Normal processing does not necessanly provide a definite positioning of the slitting.
3.6 aluminum killed
steel which has been deoxidized with aluminum sufficiently to prevent the evolution of gas during solidification
4 DimensIons
4.1. Hot-roIled carbon steel sheet is commonly produced in the range of thickness 0,8 mm to 12,5 mm
inclusive, and in widths of 600 mm and over, in coils and cut lengths.
4.2 Hot-reduced sheet less than 600 mm wide can be slit from wide sheet and will be considered as sheet.BS ISO 3573 pdf download.
