It is suitable for applications where the surface is of prime importance. Commercial quality sheet (CR1) is intended for general fabricating purposes where sheet is used in the flat condition or for bending, moderate forming, and welding operations. It is produced in thicknesses of 0,36 mm and thicker (commonly produced up to 4 mm) and in widths of 600 mm and over, in coils and cut lengths. Drawing quality sheet (CR2, CR3, CR4, CR5) is intended for drawing or severe forming, including welding. It is produced in thicknesses of 0,36 mm and thicker (commonly produced up to 4 mm) and in widths of 600 mm and wider, 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: CR2 — Drawing quality CR3 — Deep drawing quality CR4 — Deep drawing quality aluminum killed (non-ageing) CR5 — Extra deep drawing quality (stabilized interstitial free) Interstitial free steel (IF steel) can be applied on orders of CR2, CR3 and CR4, provided that the customer is informed of the substitution and related shipping documents reflect the actual material shipped. Cold-reduced sheet less than 600 mm wide can be slit from wide sheet and will be considered as sheet |
