Product Overview

What are Titanium Grade 7 Threaded Rods?

Titanium Grade 7 threaded rods are corrosion-resistant fasteners manufactured from titanium alloy UNS R52400, which is essentially Grade 2 titanium stabilized with a small addition of palladium (0.12-0.25%). This addition dramatically enhances resistance to crevice corrosion and pitting in strong acids and chloride-bearing environments. Titanium Grade 7 threaded rods are produced to ASTM B348 and ASTM B381 standards, offering excellent weldability, ductility, and mechanical strength for critical chemical processing and marine applications.

These rods are widely specified for use in highly corrosive environments such as chlorine dioxide bleaching plants, desalination, and chemical reactors, where standard titanium or stainless steel fasteners would fail. Grade 7’s unique combination of mechanical properties and corrosion resistance makes it the preferred choice for threaded rod applications in the harshest industrial conditions.

Material Chemistry

Titanium Grade 7 Chemical Composition

Titanium Grade 7 Threaded Rods are manufactured from commercially pure or alloyed titanium with elemental limits strictly controlled per ASTM and AMS specifications. Oxygen and nitrogen contents govern strength and ductility in CP grades; aluminium and vanadium additions in Ti-6Al-4V (Grade 5) deliver 896 MPa tensile strength at 4.43 g/cm³ density.

Why Titanium Grade 7 Alloy Composition Matters for Threaded Rods

Palladium (0.12–0.25%) — Superior Acid Resistance
The addition of palladium to titanium dramatically increases resistance to crevice corrosion and pitting in reducing acids (e.g., hydrochloric, sulfuric) and chloride-rich environments, making Grade 7 threaded rods ideal for chemical plant and desalination use.
Low Interstitials — High Ductility
Strict limits on oxygen, nitrogen, and carbon ensure excellent ductility and toughness, allowing Grade 7 rods to be cold-rolled, machined, and welded without embrittlement or cracking.
Titanium Base — Lightweight & Biocompatible
The titanium base provides a high strength-to-weight ratio and is non-toxic, making these rods suitable for both industrial and select medical applications where corrosion and weight are critical factors.
