I see a lot of people talking about stainless here without listing the common alloy types:
304 Stainless Steel:
Composition: 18% Chromium, 8% Nickel.
Properties: Excellent corrosion resistance, good formability, non-magnetic (may become slightly magnetic after cold working).
Common Uses: Kitchen equipment, food processing equipment, architectural trim, and general hardware.
316 Stainless Steel:
Composition: 16% Chromium, 10% Nickel, 2% Molybdenum.
Properties: Superior corrosion resistance to 304 in harsh environments, excellent formability, non-magnetic.
Common Uses: Chemical processing equipment, medical devices, marine applications, and any environment where greater corrosion resistance is required.
430 Stainless Steel:
Composition: Approximately 17% Chromium, no Nickel.
Properties: Good corrosion resistance, strong magnetism, lower cost than 300 series.
Common Uses: Domestic appliances, automotive trim, and interior architectural features.
Tesla says they use some proprietary type thats in the 301 series.

- jtriangle 3y agoThey're likely using 301, which won't stand up to free chloride ions well. 304 or 316L would be better, n50 or n60 would be best, but you've just doubled the cost of the panels...
- algo_trader 3y agoWhat is the cheaper alternative for 316 in marine applications? Specially long term floating objects such as buoys, with minimal physical contacts, and a painting/maintenance schedule is possible
