    Stainless steel

    I recently salvaged some stainless steel running boards, when I took them in expecting to be paid for stainless, they said they were magnetic, therefore not stainless, just worth iron price. Is he correct or did I get screwed?

    Were there brackets or steel frame/supports on it? Or the actual running board was magnetic?

    I was tearing down some restaurant equipment. Initially I thought it was magnetic, but it was catching the steel backing.

    A long time ago my scrapper mentioned that if I,
    "Found stainless steel, but it was magnetic or very lightly magnetic, keep it separate" & he "would give me a good price for it"

    I expect it was, say 50% of the Stainless Steel price (which was higher then) & worth buying in largish lots (100Kg+)
    Stainless normally turns up in larger amounts that any nonmagnetic metals & weighs more too.

    IdahoScrapper may be right about the steel frame/supports. If that's the case, you were better off removing them before taking them in.

    I stripped them completely, even any plastic caps, etc.

    That's a bummer. Get a good magnet and use it on everything.

    My yard also told me if its magnetic it goes with regular steel. but one time, the same guy gave me a better price on a sink that was *lightly* magnetic and I had removed the brackets too so it wasn't catching those. So, lol, my yard confuses me sometimes but I wasn't complaining as I got better price. Now, this particular sink, when I ran the magnet over it only stuck towards the bottom. I thought it was odd but on the outside of the sink the bottom half had a white type material painted/sprayed on it so I figured maybe that stuff was attracting the magnet. Anyone know what that stuff is?

    Was the drain assembly still attached? That might be magnetic.

    newattitude- that stuff on the bottom helps to keep it from being so noisy when your running water, it's just some sort of goo and shouldn't be magnetic.

    No, the drain was off thats why I wondered if that white stuff was magnetic as it clearly didn't stick on the top half but as I moved it down it lightly *stuck* where the white goo stuff started on the other side. Weird.

    300 Series Stainless (The kind everyone is talking about when scrapping stainless) is valuable because it contains Nickel. 300 Series is never magnetic. The stainless you had was a 400 Series Stainless. This type of stainless is magnetic and technically has a value slightly higher than regular light iron. The price is so close, however, that every yard I've been to, buys that stainless as light iron. This is the way I purchase stainless as well. There seems to be a lot of confusion about this, so I hope my post clears some things up.

    Oh, also with the lightly magnetic stuff, it varies yard to yard. Try to get to know the buyers at your yard and be friendly with them. They will often let a bit of lightly magnetic stainless go by.

    At my yard magnetic stainless steel is the same as steel, slightly magnetic then it depends on the guy working the scale. The usually guy, Joe, I know pretty well and he will give me a slightly better price than regular steel. As Err0rX said it really depends on your yard but it never hurts to ask.

    Bring a magnet when checking these things. If there is even one iron bolt on it, they will pay you iron. Make sure all steel is removed to get the stainless price. The reason is they have to pay me to remove your steel and make it clean stainless. I use a plasma cutter, and it gets expensive.
    We have a huge water tank out back that they paid iron for, I cut like 4 water ports out of it and used the plasma to pop some nuts off. We turn it in to out mother-yard and we get paid stainless price. That's called an upgrade.

    I think the 'white goo' is probably the protective plastic film thats often on stainless steel sheetmetal.

    The sinks are made seperate & the sheetmetal firm welds them into their stainless steel sinktop then grinds down the welds & sands/grinds/polishes the weld down till you can't see the weld from the top.

    Bleach 'eats' stainless steel if its left on it long enough, so I found when I noticed tiny holes in my SS frypan, then the sinktop....
