标准简介：1.1   This International Standard specifies requirements for 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 the surface is of prime importance. This product is commonly rolled on a narrow strip mill.
1.2  Commercial quality strip (HR1) is intended for general fabrication purposes where strip is used in the
flat condition, 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.
1.3  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 according 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 aluminum killed
1.4  Hot-rolled steel strip can also be rolled on a wide continuous mill and slit into narrower coils. However, all attributes of the finished product meet the requirements of this International Standard.
