For plates up to 10 inches excl in thickness the tolerance under the specified thickness is 0 010.
Common stainless steel sheet thickness.
Foils sheets and plates are pretty much the same with the only difference being in thickness.
The gauge number 18 holds no relevance to the actual measurements.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Thickness is measured along the longitudinal edges of the plate at least 3 8inches but not more than 3 inches from the edge.
304 stainless steel has a high resistance to corrosion and lends itself to many types of fabrication making it one of the most widely used forms of stainless steel used today.

There are other measurement units used to categorise metals by thickness though.
