This palladium-stabilized marvel extended service life by over 300%, slashing replacement costs and downtime for the chemical operator while enabling seamless deep-drawn reactor liners. Now, leaders in oil & gas, marine desalination, pharma, and power turn to it over common grades for unmatched crevice corrosion resistance in harsh, chloride-laden environments.
Titanium Grade 11 foil (UNS R52250, Alloy 3.7225), a palladium-enhanced unalloyed titanium (Ti-0.2Pd), outperforms Grade 2 with superior resistance to reducing acids, chlorides, and seawater thanks to Pd's catalytic effect preventing anodic dissolution. Its maximum ductility (elongation up to 29%) suits "ductile Titanium Grade 11 foil 0.05mm to 1mm for pharmaceutical distillation" and custom forming, unlike stronger but less formable alloys.
Ideal for "seawater-resistant Titanium Grade 11 foil for coastal power plant condensers" and "UNS R52250 foil for desalination plant membranes," it resists crevice corrosion in stagnant conditions where Grade 2 fails.
