Linguistically wrong, factually correct. There are many grades of stainless steel, and they will in fact develop rust over time. 430 is a mild stainless steel

Linguistically wrong, factually correct. There are many grades of stainless steel, and they will in fact develop rust over time.
430 is a mild stainless steel that has decent corrosion resistance, but you're not going to want to test it too hard.
304 is more common, albeit more expensive, and will hold up pretty well under most normal conditions.
Any expected prolonged exposure to salt requires 316 or better, though.
- wahern 4y agoManufacturing quality matters, too. Cheap stainless steel (e.g. basically anything from a Lowes or Home Depot, or elsewhere standards aren't rigorously enforced, like so much exterior cladding, trim, and fasteners on modern construction) will often rust almost immediately in spots as the alloying isn't sufficiently homogenous or pure.

- bee_rider 4y agoWhat do the numbers mean?(slightly confused because your description of 316 makes it sound generally more badass than 304, but I can’t fit that in sequence with 430 being the worst).
