In a high-stakes chlor-alkali plant off India's coast, corrosive brine eroded standard titanium linings within months, halting production and costing millions in downtime. Procurement heads switched to Titanium Grade 3 Foil UNS R50550 ASTM B265 from Aurico Alloys LLP, delivering unmatched structural integrity and resuming operations seamlessly. This higher-strength CP titanium foil transformed reliability for chemical engineers facing aggressive oxidizing acids and high-velocity brine .
Table of Contents:
Titanium Grade 3 foil (UNS R50550, ASTM B265) stands out as a commercially pure titanium with elevated oxygen content, offering 20-30% higher yield strength than Grade 2 typically 380 MPa vs 275-345 MPa while retaining excellent formability and corrosion resistance in seawater, acids, and caustics . Available in thin gauges from 0.1mm to 1mm, it's perfect for high-pressure chemical reactor liners, marine heat exchangers, and pharma distillation components where Grade 2 deforms under load .
Unlike softer Grade 1 or 2 foils prone to distortion in pressurized systems, Grade 3 provides superior resilience: tensile strength ≥450 MPa and elongation ≥18%, with low density for lightweight efficiency . Aurico Alloys LLP, trusted Titanium Grade 3 foil supplier in Mumbai, stocks these as exporter from India to abroad, serving oil & gas umbilicals, power condensers, and hardware stores with affordable, authentic material certified to EN 10204/3.1 .
For OEM fabricators and industrial supply stores, Titanium Grade 3 shim stock excels in subsea pressure housing and aerospace-grade airframe skins, resisting pitting in chloride environments far better than alternatives . Custom cut-to-size rolls support electronics shielding and seawater-resistant offshore hardware, ensuring compliance and uptime .
