Need to identify steel type

[schnipp]

I have a list of components in some metal samples found in my product by customers.

It is 88.2% Fe with the following additives:
8200 ppm Mn
1000 ppm Cr
2900 ppm Ca
1800 ppm Al
1500 ppm Co
857 ppm Ni

With traces of Mg, K, Co, and several others.

Is there a website that would list what grade of stainless this is? Thanks for replys

Are you sure of the chemical analysis?
1000 ppm Cr = 0.1% Cr and
857 ppm Ni = 0.0857% Ni would not make up a stainless.
It is not clear why your customers should find the composition of your products.

I didn't do the analysis, so I have to go by what the numbers say.

I dug a little further and found out some more info.

My product is food grade powdered sugar. Our customer runs the product across magnets as it unloads from a rail car. They found 'highly magnetic' pieces on the magnet after processing a certain car that had my product in it. The samples were sent to my home office and analyzed with the above results.

Thinking about it a little more, I realize this is not stainless (especially with the low chromium and nickel numbers). I asked for carbon content, but the sample was consumed in the first test and carbon was not analyzed.

I'm sorry if this is in the wrong forum. I didn't see a steel group. Mods can move as necessary.

Sounds like rusty carbon steel detritus has made its way into your sugar.

Or weld slag.

Nah, it wasn't welding slag.

Current thinking is a bearing came apart somewhere in the process and the magnets and metal detector didn't catch it.
