[TheForge] where do I get?

Jim...will a respirator take the hexavalent chromium out?

A second question for the knowledgeable folks here...
I'm assembling a semi submerged water intake for my system out of 
assorted scrap stainless. It's pretty clear that there are 
several, quite different alloys going into the assembly...hard, 
softer, magnetic and non magnetic.
What are the corrosion consequences of the mixed stainless? 
(Stainlesses?)

The prior intake ( the frog coffin) was enameled steel, galv 
steel, brass and copper. It lasted about 15 years. The steel 
parts are crumbling...1" galv schedule 40 pipe is perforated...
A fine demonstration of the drawbacks of mixed metal assemblys.
