In my case, the finish being applied was a #4 finish to a stainless steel sheet. That was the nice finish that had to be protected.

When I first heard #4 finish used in conversation, I was the guy nodding my head as if I knew of the #4 finish they spoke.
In reality, I had no idea what a #4 finish was, aside that it was special. While I was nodding knowingly, I was tilting my head like a curious dog on the inside. I endeavored to make a few Google searches when I got back to my desk.
|Admit it! We've all looked like this at one point or another!|
And Google paid off in spades. I found the website for the Stainless Steel Information Center.
Not only did I find exactly what I needed to know about #4 finish, I found a wealth of information on stainless steel, I found definitions, information on composition, applications, corrosion properties. The list goes on and on.
I haven't even gone through the entire site yet! But I know that I will eventually. I'll refer to this site often!
I've already started downloading some of the handbooks for myself.
But if you're using stainless steel, thinking about using stainless steel, or you're a student wanting to learn about stainless steel, then this is a resource well worth considering.
And if you know any other great engineering materials, or anything at all, feel free to share with a comment!
And by the way! A #4 stainless finish is what you'd find on appliances, architectural wall panels, and tank trailers, among other things.
But now you have the resources to read that yourself!
