Titanium Grade 7 (UNS R52400) Sample MTC
Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for Titanium Grade 7 (ASTM B348 UNS R52400). Inspect the exact documentation your QA and engineering teams will receive with every extreme chemical-resistant fastener order from Ananka Fasteners.
What's Inside This Titanium Grade 7 MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for Titanium Grade 7, the most corrosion-resistant of all titanium alloys. It is structurally identical to Grade 2 but heavily alloyed with Palladium to survive reducing acids and aggressive chemical environments.
- Full Traceability: Certified with TC No.: S74/26-XX and corresponding ASTM B348 specifications.
- Palladium Addition: Detailed breakdowns verifying the precise addition of Palladium (0.12% - 0.25%). This precious metal addition drastically lowers the overvoltage required for passivation, effectively immunizing the fastener against crevice corrosion and reducing acids at high temperatures.
- Interstitial Controls: Strict monitoring of Oxygen, Iron, and Nitrogen to maintain the excellent cold formability and ductility characteristic of unalloyed titanium.
- Mechanical Properties (Annealed): Comprehensive reporting of Tensile Strength (425.50 MPa), Yield Strength (320.40 MPa), Elongation (26.50%), and Hardness (162 HB), perfectly mirroring Grade 2 mechanics.
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — Titanium Grade 7 MTC Certificate
Why use Titanium Grade 7 instead of Grade 2?
Mechanically, Grade 7 and Grade 2 are identical. The defining difference is that Grade 7 contains between 0.12% and 0.25% Palladium. While Grade 2 is excellent in oxidizing environments (like seawater), it can suffer from crevice corrosion in hot halide media or attack by reducing acids (like hydrochloric or sulfuric acid). The Palladium in Grade 7 extends the passive range of the titanium, making it virtually immune to crevice corrosion and significantly extending its life in reducing environments.
How does Palladium improve corrosion resistance?
Palladium is a noble metal. When added to titanium, it facilitates cathodic depolarization. In simple terms, it shifts the corrosion potential of the titanium alloy into the passive region, forcing the titanium to continuously reform its protective oxide layer even in hot, acidic environments that would normally strip the oxide layer away.
Are the materials free from radioactive contamination?
Yes, the document strictly states that the material is free from radioactive contamination and undergoes a 100% visual inspection to ensure it is free from defects.
