Okay so I have a question about stainless steel vs aluminum, I was scrapping a small drawer dishwasher and I found alot of stainless steel pieces around it, some was magnetic and some wasn't but I know it was all stainless steel, can someone please tell me the difference and how the prices vary. Thanks - Devin The Scrapper

The stainless will throw off sparks if you hit it with a grinder where aluminum will not. Hope this helps.

If a magnet sticks most yards will consider it shred but ask to make sure.

Stainless that has Chromium and no nickel is 400 series and while just as shiny, it is not as stain and corrosion resistant and is magnetic.

Yup, at the yard Iuse if a magnet sticks it goes in the shred at about .10# if the magnet does not stick it is what I call true stainless and goes for .50#.

Devin, just to clarify. Is your question: what's the difference between aluminum and stainless or what is the difference in variations of stainless?

There is another grade of stainless steel, it is called 17-ph
This type of stainless steel is magnetic.
I brought some to the yard and the guys tells me it is not stainless steel because it is magnetic.
So once again I bite the bullet and get paid for iron instead of stainless steel.

All the yards I use do this also, so it's not that unusual.

same with me
but i think the yard owners just teach their staff to test using this method only
despite knowing well that theres many other expensive types of stainless steels & other alloys which are magnetic
i suppose we just have to roll with the punches
