| Dimension | Strip: Width 25.4-1219.2mm x Thickness 0.41-4.75mm |
| Sheet: Width 1000-2000mm x Thickness 0.41-4.75mm | |
| Plate: Width 1000-2000mm x Thickness 4.75-101.6mm | |
| Density | 4.51g/cm³ |
| Condition | Sheet and Strip: Hot rolled with or without subsequent cold reduction, annealed, descaled, and leveled, having a surface appearance comparable to a commercial corrosion-resistant steel No. 2D finish. Plate: Hot rolled, annealed, descaled, and flattened, having a surface appearance comparable to a No. 1 finish. Plate products shall be produced using standard industry practices designed strictly for producing plate stock to the procured thickness. Bar, billet, forgings, or forging stock shall not be supplied in lieu of plate. |
