In a coastal sulfuric acid plant plagued by crevice corrosion eating through reactor linings at 80°C brine conditions, downtime soared until Titanium Grade 7 Foil UNS R52400 ASTM B265 Ti-0.15Pd from Aurico Alloys LLP intervened. Its palladium enhancement slashed corrosion rates by 90% vs standard titanium, restoring zero-failure operation.
Table of Contents:
Titanium Grade 7 foil (Ti-0.15Pd, UNS R52400, ASTM B265) is CP titanium with 0.12-0.25% Pd for unparalleled crevice corrosion resistance in reducing acids like HCl and H2SO4, outperforming Grade 2 by resisting attack up to 260°C where Grade 2 fails . Mechanicals mirror Grade 2 (345 MPa UTS, 275 MPa yield) but with superior ductility for gaskets and linings .
Aurico Alloys LLP, Titanium Grade 7 foil supplier in Mumbai, stocks affordable, authentic material as trusted supplier, stockist, exporter of Titanium Grade 7 UNS R52400 ASTM B265 for chemical, oil & gas, marine, pharma, power, aiding hardware stores with verified MTC EN 10204/3.1 . Perfect for hydrochloric acid processing units .
Unlike plain CP grades prone to crevice failure in chlorides, Pd-enhanced Grade 7 thrives in hot brine evaporation and nuclear waste containers. Thin gauges enable precision pharma distillation.
