Product Overview

What are Titanium Grade 7 Studs?

Titanium Grade 7 studs are high-performance 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 corrosion resistance, especially in strong reducing acids such as hydrochloric and sulfuric acid, making Grade 7 the most corrosion-resistant titanium grade available for fastener applications.

These studs are specified for critical chemical processing, desalination, and pollution control equipment where maximum resistance to crevice corrosion and stress corrosion cracking is required. Titanium Grade 7 studs are produced in accordance with ASTM B348 and ASTM B381 standards, ensuring full traceability and mechanical integrity for demanding industrial environments.

Material Chemistry

Titanium Grade 7 Chemical Composition

Titanium Grade 7 Studs 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.

Chemical Composition per ASTM B348

ElementComposition (%)
Titanium (Ti)Balance
Palladium (Pd)0.12-0.25
Iron (Fe)0.30 max
Oxygen (O)0.25 max
Carbon (C)0.08 max
Nitrogen (N)0.03 max
Hydrogen (H)0.015 max
Other Elements (each)0.10 max
Other Elements (total)0.40 max
? All heats verified by NABL-accredited spectrometry. Palladium content confirmed for every batch.

Why Titanium Grade 7 Alloy Composition Matters for Studs

Palladium (0.12–0.25%) — Acid Resistance
The addition of palladium to commercially pure titanium dramatically increases resistance to reducing acids, especially hydrochloric and sulfuric acid. This makes Grade 7 studs the preferred choice for chemical plant and pollution control equipment fasteners.
Low Interstitials — Ductility & Weldability
Strict limits on oxygen, nitrogen, and carbon ensure excellent ductility and weldability, allowing Grade 7 studs to be welded into assemblies without embrittlement or loss of corrosion resistance.
No Alloying with Aluminum or Vanadium
Unlike Grades 5 and 23, Grade 7 is unalloyed except for palladium, ensuring maximum corrosion resistance in both oxidizing and reducing environments, with mechanical properties similar to Grade 2.

Titanium Grade 7 studs are available to DIN 976 (metric threaded rods and studs), ISO 898-1 (mechanical properties), ASME B16.5 (flange stud bolts), and ASME B18.31.2 (inch continuous thread studs). Custom thread forms such as BSP, Whitworth, and fine pitch are available on request with short lead times.
Use a molybdenum-based or PTFE anti-seize compound (such as Molykote 1000 or Loctite LB 8014) on Titanium Grade 7 studs. This prevents galling and seizing during assembly. Avoid copper-based anti-seize to prevent galvanic corrosion with titanium. Reduce torque values by 20% when lubricated.
Yes – Titanium Grade 7 is specifically designed for maximum resistance to reducing acids such as hydrochloric and sulfuric acid, thanks to its palladium addition. It is the preferred fastener material for acid plant equipment, outperforming all other titanium grades in these environments.
