Stainless Steel Plate
Stainless steel coil plate – ASTM A240M
The most efficient route for a stainless steel production mill to produce plate (5mm and over) is in coil form. The coil is then further downstream processed by the mill or through a service centre with equipment to flatten (often called ‘levelling’) and cut to length.The maximum plate width produced by mills from coil is 2000mm and the maximum thickness is 13mm for hot rolled and 8mm for cold rolled.
Atlas, through the AMP coil service centre, has the capability to process large stainless steel coils in thickness up to 6mm (8mm for aluminium) and in widths to 2000mm.
This enables an extensive range of cold and hot rolled coils to be held with the flexibility to convert into small coils, sheet, strip and plate in standard and customised lengths.

Other grades available, but not always ex-stock.
Grades: 301L, 310, 321, 2205, 253MA.
Coil plate is commonly stocked in dual certified grade, i.e. 304/304L and 316/316L.
Stainless steel quarto plate products – ASTM A240M
Another method of producing stainless steel plate within and beyond the thickness range of coil production is from a slab of steel that is rolled in the flat condition to a specified length, width and thickness. The product of this process is commonly referred to as quarto plate and is available from mills in thickness from 5mm and above and widths to 4000mm in some thicknesses.
The standard grades and thickness for quarto plate are as follows:
| Grades | 304/304L, 316/316L, AtlasCR12, 321, 321H, 2205, 253MA |
| Thickness (mm) | 5.0, 6.0, 8.0, 10.0, 12.0, 13.0, 14.0, 16.0, 20.0, 32.0, 40.0, 50.0 |
| Width (mm) | 1500, 2000, 2500 |
| Length (mm) | 6000, 7500, 8000 |
| Finish | No. 1 |
Quarto plate is commonly stocked as a dual certified grade, i.e. 304/304L and 316/316L.
