Can someone please point me in the right direction. I am looking for the tolerances for stainless steel sheet metal for all gages. For example I know that 20 gage stainless steel is .0359" but what are the tolerances, plus or minus what? Is there a standard for the steel industry that says for 20 gage stainless steel the tolerances are this. Or does it depend on the steel mill where the sheet metal is produced. Thanks, Matt
