I got that S/S sink and after removing everything ferrous (brackets, drain...), the main part is some kind of mixed alloy. Some parts are totally non-magnetic and some are lightly magnetic. It is totally random. I guess that yards will say that it is ferrous, because magnet sticks in some spots, but I feel like it is not full 100% right. Around here, dirty or ferrous stainless steel all go with shred. Your opinion?
NEW TO SCRAPPING? READ THIS: Build up your horde of magnetic and non-magnetic metals in two piles until you have a better understanding of the business. Magnetic material has low value and is mostly always steel / shred / short iron. Read old threads about non-magnetic metals and ewaste (and how to sort them), but don't forget that they generally have absolutely no tolerance for contamination (screw / iron / foreign material).

If you bend stainless 304 it will become magnetic. Thats why some sinks have magnictivity (is that even a word?) where they press the sink part into the flat sheet at the factory. i have bent some SS b4 and it became magnetic and some does not become magnetic. I always sell mine as clean stainless but because of my reputation at the yard they don't even check them.Originally Posted by CopperMiner
Plus i learned at the new yard that lightly magnetic SS is considered just a different grade of stainless cause the magnet does a hard pull to steel compared to a slight pull from SS.
