material selection in sulfuric acid

[ras85]

i need to select material for pump shaft in sulfuric acid at 98% concentration and 120 C. i would like to know any one has experience on chrome plating coating on this application or maybe kindly suggest another solution.

First off; review information on pumps suitable for sulfuric acid service

Second, review information on suitable materials and the effects of velocity. Ni-base alloy would be required given flow induced effects on material performance and 120 deg C.

Third, chrome plating would not be recommended for this application.

Get a hold of the MTI Material Selector series MS-1.
It is the best Sulfuric guide that there is.
