Title
Hot-rolled carbon steel sheet of commercial and drawing qualities

International Organization for Standardization

Publication Date:
Apr 1, 2008

Scope:

This International Standard applies to hot-rolled carbon steel sheet of commercial and drawing qualities.

Hot-rolled steel sheet 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.

NOTE Steel sheet that is to be subjected to subsequent rerolling is not covered by this International Standard.

Commercial quality sheet (HR1) is intended for general fabricating purposes where sheet is used in the flat condition or for bending, moderate forming and welding operations. It 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.

Drawing quality sheet (HR2, HR3, HR4) is intended for drawing or severe forming, including welding. It 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. Drawing quality sheet 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 property requirements do not apply. Drawing qualities are identified as follows:

HR2 — Drawing quality

HR3 — Deep drawing quality

HR4 — Deep drawing quality aluminum killed

Hot-reduced sheet less than 600 mm wide can be slit from wide sheet and will be considered as sheet.
