Product Overview

What are Titanium Grade 9 Nuts?

Titanium Grade 9 nuts are high-performance fasteners manufactured from a titanium alloy containing 3% aluminum and 2.5% vanadium (UNS R56320). This alpha-beta alloy, also known as Ti-3Al-2.5V, offers a unique combination of moderate strength, excellent corrosion resistance, and superior weldability. Titanium Grade 9 nuts are lighter than steel and provide outstanding resistance to seawater, chlorides, and a wide range of chemicals, making them ideal for critical bolted joints in marine, aerospace, and chemical processing environments.

These nuts are produced in accordance with ASTM B348 and ASTM F467 standards, ensuring consistent mechanical properties and dimensional accuracy. Titanium Grade 9 is often specified where Grade 2 lacks strength and Grade 5 is over-specified, striking a balance between performance and cost for demanding applications.

Material Chemistry

Titanium Grade 9 Chemical Composition

Titanium Grade 9 Nuts 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

? All heats verified by NABL-accredited spectrometry. PMI available on request.

Why Titanium Grade 9 Alloy Composition Matters for Nuts

Al (2.5–3.5%) — Strength & Weight Reduction
Aluminum increases the strength-to-weight ratio of Titanium Grade 9 nuts, making them ideal for aerospace and high-performance marine assemblies where every gram counts.
V (2.0–3.0%) — Enhanced Weldability
Vanadium improves weldability and ductility, allowing Titanium Grade 9 nuts to be used in welded structures and pressure vessels without embrittlement or loss of corrosion resistance.
Low Interstitials — Superior Corrosion Resistance
Strict limits on oxygen, nitrogen, and carbon ensure that Titanium Grade 9 nuts maintain excellent resistance to pitting, crevice, and stress corrosion cracking in aggressive environments.

Browse expert answers to common questions about Titanium Grade 9 Nuts from RealBolt — covering grade selection, ASTM B348/F467, seawater immunity, weight saving, galling precautions, and certification. Contact our technical team directly for project-specific guidance on Titanium Grade 9 nuts selection and pricing.
Titanium Grade 9 hex nuts are available to DIN 934 (metric hex), ISO 4032, ASME B18.2.2 (inch hex and heavy hex), and DIN 985 (nyloc lock nuts). Prevailing torque and all-metal lock nuts are also available. Custom thread forms (BSW, BSF, Whitworth, BSPP) can be supplied on request with a typical lead time of 2-3 weeks.
Always use a PTFE-based or molybdenum disulfide (MoS2) anti-seize lubricant on Titanium Grade 9 nuts and bolts to prevent galling and cold welding. Avoid copper-based lubricants, as they can cause galvanic corrosion with titanium alloys. Lubricated assembly also ensures consistent preload and easier disassembly.
Yes – Titanium Grade 9 nuts are completely resistant to seawater corrosion, including in crevice and stagnant conditions. They are widely used in shipbuilding, offshore platforms, and desalination plants. No special coatings or cathodic protection are required for marine service.
No MOQ for standard metric and inch sizes (M6-M24) held in stock – we supply from single pieces for urgent requirements. Custom sizes or special coatings may require a minimum batch of 10 kg. Quantity discounts are available at 50, 200, and 500 pieces.
