Titanium Grade 2 Foil UNS R50400 | ASTM B265 CP Titanium Grade 2
Table of Contents:
In a bustling chemical plant near Mumbai's petrochemical belt, a recurring failure in heat exchanger gaskets exposed to hot chlorate solutions led to frequent shutdowns, costing procurement teams lakhs in lost production until Titanium Grade 2 foil liners were installed, extending service life by over 5 times compared to Hastelloy alternatives due to its superior resistance to oxidizing acids and halides .
Titanium Grade 2 (UNS R50400, Werkstoff 3.7035), a commercially pure (CP) alpha titanium alloy, offers exceptional corrosion resistance from its stable passive oxide layer, making it ideal for chemical reactors, marine desalination, and pharma vessels where 316L stainless fails rapidly in chloride or oxidizing environments. With a density half that of steel, it delivers weight savings critical for offshore oil & gas instrumentation and power plant condensers .
Unlike Grade 5 (Ti-6Al-4V) which trades ductility for higher strength in aerospace, CP Titanium Grade 2 foil excels in formability for thin gauge applications like shims and gaskets, with elongation up to 20% enabling complex fabrications without cracking . Continuous service up to 425°C (800°F) suits flue gas desulfurization (FGD) and waste incineration, where its resistance to sulfuric acids outperforms nickel alloys in cost-per-year metrics .
High-quality Titanium Grade 2 Foil ready for industrial use.
