1 This International Standard applies to hot-rolled carbon steel strip of commercial and drawing qualities.
NOTE Steel strip that is to be subjected to subsequent rerolling is not covered by this International Standard.
Hot-rolled steel strip is suitable for many applications where the presence of oxide or scale, or normal surface imperfections disclosed after removal of oxide or scale, are not objectionable. It is not suitable for applications where surface is of prime importance. It is rolled on a narrow strip mill.
2 Commercial-quality strip (HR1) is intended for general fabrication purposes where strip is used in the flat, or for bending, moderate forming and welding operations. It is commonly produced in the range of thicknesses 0,65 mm to 12 mm inclusive, and widths up to 600 mm exclusive, in coils and cut lengths.
3 Drawing-quality strip (HR2, HR3, HR4) is intended for drawing or severe forming, including welding. It is commonly produced in the range of thicknesses 0,65 mm to 12 mm inclusive, and widths up to 600 mm exclusive, in coils and cut lengths. Drawing-quality strip is furnished to all the requirements of this International Standard or, by agreement when ordered, to fabricate an identified part, in which case the mechanical properties in Table 2 do not apply. Specific drawing qualities are identified as follows:
HR2 Drawing quality
HR3 Deep-drawing quality
HR4 Deep-drawing quality, aluminium-killed
