Guessing the grade of stainless from how it looks?
(OP)
If I had some dull grey stainless, not shiny or bright or silvery like 316 or 302, what grade might it be? Any guesses? Thanks. Ant.

I used to cast alloys and could separate grades by smell, we added S to some and not to others.

Even SS will corrode after a while.

For example, take a forging operation that produces the same valve in carbon steel, 410 stainless, and 316 stainless. I could tell by looking at the as-forged valve bodies and determine which was which because of the differenes in the appearance of the scale. Now, this is a result of education and experience so I could spot and understand what caused the scale to take on different appearances, along with knowing that they had to be one of those three grades. This was also years ago; today I might be able to tell if one was A105 or stainless by appearnace, but I wouldn't trust myself.
