Hello I have a sulfuric acid (H2SO4) heat exchanger application and I wanted to know the benefits of the tantalum surfaces over a PTFE or Hastelloy C276 (These are the two other materials we are considering). My…
Valves for Strong Acids

Hello, I have an application that requires acid resistant ball valves in a solution that is mostly sulfuric acid. We have had mild success with Hastelloy valves but after a few months it is impossible to get leak tight…
Tantalum Thickness for H2SO4
Ben Davis · · 1 reply
Hello, My application utilizes a range of H2SO4 from 99% down to 15% at about 120C. I know most materials like Zirconium and Hastelloy generally cannot survive under those various conditions and my understanding is that…
Sulfuric Acid Agitator

We are designing an agitator for a sulfuric acid process containing 75-80% sulfuric acid near the boiling point of 160-170C. We are interested in Ultramet CPT's tantalum surface but wanted to understand the corrosion…
Range of Sulfuric Acid Tantalum is Good For?
JohnH · · 1 reply
Hi, My application uses range of sulfuric acid (H2SO4) from 98% to about 10% at temperature less than 200F. Will your tantalum diffusion surfaces be corrosion resistant in that range of conditions?
H2SO4 with Ferric Ion Contamination
Dan · · 1 reply
Hello, I know Hastelloy C276 does reasonably well in clean H2SO4 but corrodes at a much faster rate when the H2SO4 get contaminated with impurities like ferric ions. Is the tantalum surface produced by Ultramet CPT…
Diluting Sulfuric Acid

Hello, I have some corrosion issues when trying to dilute hot H2SO4 from 99% down to about 90%. As this dilution creates an exothermic condition I am using a plate and frame heat exchanger to remove the heat.…
