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 Atlas Metals Processing 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.

Grade Thickness (mm) Coil width (mm) Finish
304/304L 5.0 1500 2B
316/316L 6.0 2000 No. 1
304/304L 8.0 1500 No. 1
316/316L 10.0 2000  
AtlasCR12 5.0 1250 No. 1
AtlasCR12Ti 6.0 1500  

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 (HRAP)

Quarto plate is commonly stocked as a dual certified grade, i.e. 304/304L and 316/316L.

6.0 49.06 48.08
8.0 65.42 64.11
10.0 81.77 80.13
12.0 98.12 96.16

32.0 261.66 256.43
40.0 327.08 320.54
50.00 408.85 400.67

Austenitic stainless steel theoretical weight is based on 8177kg/m³
Ferritic stainless steel theoretical weight is based on 8000kg/m³

Actual weights may vary from the above due to specific grade and dimensional tolerances.
