Product Overview

What are Titanium Grade 7 Screws?

Titanium Grade 7 screws 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 unique composition provides exceptional resistance to crevice corrosion, especially in strong reducing acids such as hydrochloric and sulfuric acid environments.

These screws are specified for critical chemical processing, desalination, and pollution control applications where standard titanium fasteners may fail due to localized attack. Titanium Grade 7 screws are produced in accordance with ASTM B348 and ASTM F467, ensuring reliable mechanical properties and full traceability for demanding industrial service.

Material Chemistry

Titanium Grade 7 Chemical Composition

Titanium Grade 7 Screws 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.

? All heats verified by NABL-accredited spectrometry. Palladium content confirmed for every batch.

Why Titanium Grade 7 Alloy Composition Matters for Screws

Palladium (0.12–0.25%) — Crevice Corrosion Resistance
The addition of palladium to commercially pure titanium dramatically increases resistance to crevice corrosion, especially in reducing acid environments such as hydrochloric and sulfuric acid. This makes Grade 7 screws ideal for chemical processing and pollution control equipment.
Low Interstitials — Ductility & Weldability
Strict limits on oxygen, nitrogen, and carbon ensure excellent ductility and weldability, allowing Titanium Grade 7 screws to be used in critical assemblies and welded structures without embrittlement.
No Alloying with Aluminum or Vanadium
Unlike Grades 5 and 23, Grade 7 is unalloyed titanium with palladium only, ensuring maximum corrosion resistance and biocompatibility for sensitive applications.

Titanium Grade 7 Screws Applications — Industries & End Uses

Titanium Grade 7 Screws from RealBolt are specified across aerospace, marine, chemical processing, and medical devices where outstanding corrosion resistance and 900 MPa tensile strength are required for reliable fastener performance. Click each industry below for detailed application examples. Select an industry below to see specific Titanium Grade 7 screws application details and RealBolt stock availability.
Titanium Grade 7 screws are the fastener of choice for acid plant equipment, heat exchangers, and piping systems handling hydrochloric, sulfuric, and nitric acids. Their palladium-stabilized composition ensures resistance to crevice and pitting corrosion in highly aggressive reducing environments where other titanium grades may fail.
Used in evaporators, brine heaters, and seawater piping systems, Titanium Grade 7 screws provide long-term durability against chloride-induced corrosion and biofouling. Their superior crevice corrosion resistance makes them ideal for critical joints and flanged connections in desalination plants.
Specifically specified for flue gas desulfurization (FGD) systems, stack internals, and scrubber assemblies, these screws withstand acidic condensates and high humidity environments, maintaining integrity where stainless steel fasteners corrode rapidly.
Titanium Grade 7 screws are used in reactors, fermenters, and process piping where ultra-high corrosion resistance and biocompatibility are required. Their non-toxic, non-magnetic nature makes them suitable for cleanroom and sensitive process environments.
