Thanks Chris. This was really useful. I spent this morning trying to figure out my stainless pile and ended up tossing it all into pressing steel. Its a really frustrating task, but your info is a great help for future sorting.
Excellent Chris about a really complex subject. The magnetic and nonmagnetic stainless has been a problem for years. Thanks for sharing this important information with the community. Good info for all. 😎😎⛏⛏🔥🔥
Chris ...... thank you again if I had to guess I bet I make 1/3 more and the scrap yard because of you and sale more things then scrap them and that’s 100% more money because I’ve never done that .. we appreciate your channel and your time brother.. THANK YOU CHRIS 👊🏻🙌🏻👍🏻
Such a good help Chris! I understand you do not want to check ALL magnetic stainless, but why would you NOT collect magnetic stainless that you know is stainless? Like utensils, kitchen appliance parts and gadgets, medical stuffs, or even stuff that says 'stainless'. Seems like I should have a bucket for magnetic stainless that I do not have to test.
It's a matter of storage and taking separate lots to the scrapyard for me. There's just not enough difference in the price of magnetic stainless to normal steel to make me want to separate it and take it to Melbourne. I have almost a 2 hour drive to my yard! It's certainly not a silly idea to save it separately if you are sure it's stainless!
I sometimes get small pieces of yellow brass which are very slightly magnetic. (It's still yellow when scratched) I usually throw it in with brass. I have wondered if I'm scamming the scrapyard?? I'm assuming that it has a small amount of iron in it.
That's the troubles with alloys CS - it's not just brass or stainless, each piece could be a slightly different alloy containing various metal elements. I'd say your slightly magnetic brass pieces could have a small percentage of nickel in the alloy. I'm sure the yards allow for that and understand that we scrappers aren't qualified metallurgists!
Another great video. Sorting out stainless alloys can be very difficult even for me. Be careful quoting from Wikipedia when it is all about what is in alloys. In one of my videos I quoted from wikipedia that the alloy that is used to glue rare earth magnets to in hard drives was a high nickel content alloy. One of my viewers said that wikipedia was wrong so I ground the surface with a angle grinder and it rusted very quickly. Nickel alloys do not rust. Also nickel is very weakly magnetic and this piece from the hard drive was strongly magnetic.
I would hold all your 316 until it's recognized by your scrap yard. Don't give your good money away for 304 prices. By the way, stainless 304 will be attracted very slightly to a high powered (neodymium) magnet where's 316 will not have any attraction and may sometimes be marked 316 by any reputable manufacturer. Thanks for the video. Imho
Honestly, this video should be redone because most stainless steel IS slightly magnetic & although it can't be detected magnet in hand, it can be detected with a light magnet on a string. This video ignores pot metal, which is both dense & non magnetic, but not as tough as SS. Austenetic SS is completely non-magnetic, so I was hoping to see examples of that.
Thanks for your input David. For the purposes of a scrapper, SS can definitely be split into magnetic & non-magnetic (yes, even though it is very slightly). That's as complicated as it needs to be! I also ignored zinc and some other less common metals as that just starts to get confusing as a beginner's scrap guide. My yard buys pot metal as cast aluminium by the way. Thanks for watching 😊
