Yes,
Many years ago,I was involved with the replacement of a "caustic concentrator" for a midwest chemical company. The vessel was of low pressure design, about 22 feet tall and used LP steam to concentrate caustic soda to ~72%
The bottom half of the vessel was fabricated from plate that was 3/16" Alloy 200 (pure nickel) bonded to 5/8" carbon steel.
According to the Nickel Development Institute ( alloy 200 is the best material for hot concentrated caustic solutions.
What is BH4 ?
I tried a couple of websearches, but came up with nothing ?
