<Look for 18-8 or 300 series stainless steel. The 18 means 18% chromium and

## 18-8 can still be found, but for the most part, the 18-8 has been
replaced by the 3XX series of SS.
304 SS is super shiny, excellent corrosion resistance, and readily
available. 316 SS is marine grade,
and is supposed to be the ultimate in corrosion resistance for harsh
environments.. like salt spray, acid rain etc.
## as far as strength, SS is not strong material, it has the same tensile
strength as grade 2 mild steel, but plenty
good enough for most applications. Phosphor bronze is a bit stronger, but our
local suppliers dont usually carry it.
However Phosphor bronze is readily available online. I have also silver
plated phosphor bronze with the ..cool amp
goop....and ditto with brass..and also copper. IMO, silver plated
phosphor bronze is about as good as it gets.
Phosphor bronze is all I see being used by various HF SW Broadcast ant
suppliers, so they must be onto something.
