Need to identify steel type

Need to identify steel type

Need to identify steel type

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

RE: Need to identify steel type

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.


RE: Need to identify steel type

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.

RE: Need to identify steel type

Or weld slag.

RE: Need to identify steel type

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.
