Default Forming Stainless

IF you are going to weld it, 304L has low carbon and less likely to crack.

Which of the 400 series is the best choice? As I've researched 400 series, I keep running to the phrase "...not as corrosion resistant..."

I need to make a grille surround piece for a Ferrari Dino. The original part is mirror finish stainless, about .015.

Any help on sources for the stainless stock would be much appreciated.

Default 430 Stainless for Trim?

430 Series seems to be good for stainless trim. Thoughts?

I worked for a factory that made stainless steel machinery for the fast food industry. Once while doing inventory in one of the warehouses I remember seeing 400 series panels which were covered with a very light rusty haze. Nothing serious, normally you could easily remove the rust with a scotchbrite pad so long as you're ok with changing the original finish. For that reason I've always stayed away from 400 series.

430 SS mirror (mill finish is available and if doing a lot of forming/joining might be a better way to go and then polish) is what you want. it is used on most OEM car trims.
When they were actual metal.
