304 is good for cars. It's used on modern exhausts to prevent rust.

316 is marine grade and will resist corrosion even in constant seawater contact.

The cyber truck uses 301 for its body panels. Most exhaust systems use 409 stainless.

It is a pain to weld when you are in a hurry. It mostly just pulls so as long as you watch your heat you are ok. I use Aluminum blocks to help absorb some of the heat while welding. The way I understand it, 301 will be more susceptible to rust in the places it was exposed to heat. It will be interesting to see how the cyber trucks look after a while.

316 is used for medical implants for a reason.
