Re the tiny copper flake found inside the Cincinnati group stainless
steel chamber after high temperature, high pressure electrolysis for
hours (1997?) -- I looked up the composition of the stainless steel at
the Los Alamos National Lab library, and found that copper was about
5%... uh, possible electrochemical corrosion. Rich Murray
You are mistaken. There is almost no copper in 200,300 or 400 grade
stainless.
Chemical Composition of Stainless 314 (used in Dewars, 304 is similar)
* Carbon 0.25 max
* Manganese 2.00 max
* Silicon 1.50-3.00
* Phosphorus 0.045 max
* Sulfur 0.03 max
* Chromium 23.0-26.0
* Nickel 19.0-22.0
* Iron balance
