What commonly available alloy has the best corrorsion resistance
properties?

I am building a chamber that needs to last 500 years. It will be
indoors, but I need it to resist the effects of time and the elements.
I added commonly because I cannot afford some rare exotic metal.

Also, can anyone recommend a good metal rod, tube manufacter that
supplys their wares in metric sizes? (US based)

Thanks.


The 300 series stainless alloys would work fine, 316L is likely the best
amongst them. It's readily available at a reasonable price, and easily
fabricated.
