Short answer: Buyers typically use a magnet, a spark test or chemical test kits and increasingly a handheld analyser that reads the alloy composition in a second or two, which tells them the grade and whether it is the more valuable 316, and they price on the result, so a load that is already sorted by magnet and described honestly passes quickly and is paid at the right grade.
