Titanium Grade 16 Foil (UNS R52402, ASTM B265): Superior Corrosion Resistance for Chemical, Marine & Energy Industries
Table of Contents:
When a major chlor-alkali plant in the Middle East faced catastrophic crevice corrosion failure in their heat exchanger gaskets after just 18 months, the engineering team needed more than a quick fix they needed a material revolution. Enter Titanium Grade 16 UNS R52402 ASTM B265 foil: the lean-palladium enhanced titanium solution that extended service life by 400% while slashing material costs 35% below Grade 7 equivalents. Procurement heads, engineers, and OEMs in chemical, oil & gas, marine, pharma, and power generation finally found their cost-effective corrosion champion.
Titanium Grade 16 (Ti-0.05Pd, UNS R52402) represents a strategic evolution in titanium technology, delivering Grade 7-level corrosion resistance at significantly lower cost. The precise 0.04-0.08% palladium addition creates a synergistic effect that dramatically accelerates oxide film repair in reducing acids, chlorides, and crevice environments critical for chemical reactors, desalination condensers, and subsea oil & gas valves. Unlike standard CP titanium (Grade 2), Grade 16 maintains full pitting resistance equivalent number (PREN) performance in sulfuric, hydrochloric, and wet chlorine service up to 80°C.
Aurico Alloys LLP stands as a trusted Titanium Grade 16 foil supplier, stockist, exporter in India to abroad, serving hardware and industrial supply stores with authentic ASTM B265 certified material. Available in thin gauges 0.01mm to 0.1mm, our precision slit-to-width coils support custom stamping for chemical gaskets, marine sensor encapsulation, and hydrogen fuel cell bipolar plates. Full EN 10204 3.1 mill test certification ensures global project compliance for procurement teams demanding verified quality.
Why choose Grade 16 over common alternatives? Grade 2 fails rapidly in reducing acids above 50°C, while expensive Grade 7 demands 0.15% Pd. Grade 16 delivers 85-90% of Grade 7's performance at 60-70% of the cost, making it the optimal choice for OEM fabricators targeting chlor-alkali equipment, phosphoric acid evaporators, and seawater reverse osmosis systems. Aurico Alloys LLP Titanium Grade 16 foil eliminates the compromise between budget constraints and corrosion reliability.
