Key Technical Information
Hastelloy®* Inconel®**, Zirconium, Titanium, and Stainless Steel valve components are susceptible to Stress Corrosion Cracking (SCC) and pitting especially in hot acids like HCl. Tantaline® treatment offers the following beneficial characteristics:
- Chemically resistant to SCC and pitting in many aggressive media and environments.
- Tantalum layer remains passivated and inert to corrosion under high temperature (>200⁰ C) acidic conditions including concentrated hydrochloric acid (HCl) and
sulfuric acid (H2SO4).***
- Superior corrosion resistance against wet, dry chlorine atmospheres, and other chlorinated environments.
