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.

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
3CR12 5.0 1250 No. 1

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, 3CR12.
Thickness (mm) 5.0, 6.0, 8.0, 10.0, 12.0, 16.0 & 20.0.
Width (mm) 1500 & 2000.
Length (mm) 6000.
Finish No. 1 (HRAP).

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