Product Overview

What are Titanium Grade 9 Bolts?

Titanium Grade 9 bolts are high-strength, corrosion-resistant 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 weldability, and outstanding resistance to seawater and aggressive chemical environments. Titanium Grade 9 bolts are lighter than steel or nickel alloy fasteners and are widely specified for critical aerospace, marine, and chemical process applications where weight savings and corrosion resistance are paramount.

Conforming to ASTM B348 and ASTM F467 standards, Titanium Grade 9 bolts are available in a wide range of metric and inch sizes, with mechanical properties superior to commercially pure titanium but easier to fabricate than Grade 5 (Ti-6Al-4V). Their non-magnetic and biocompatible nature also makes them suitable for medical and instrumentation use.

Material Chemistry

Titanium Grade 9 Chemical Composition

Titanium Grade 9 Bolts 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
Aluminum (Al)2.5-3.5%
Vanadium (V)2.0-3.0%
Iron (Fe)0.25% max
Oxygen (O)0.20% max
Carbon (C)0.08% max
Nitrogen (N)0.05% max
Hydrogen (H)0.015% max

Why Titanium Grade 9 Alloy Composition Matters for Bolts

Al (2.5–3.5%) & V (2.0–3.0%) — Strength & Weldability
The addition of aluminum and vanadium increases the strength of Titanium Grade 9 bolts over commercially pure grades, while maintaining excellent weldability and ductility. This makes them ideal for pressure vessels and piping systems requiring field welding.
Low Interstitials — Corrosion & Fatigue Resistance
Strict limits on oxygen, nitrogen, and hydrogen ensure high resistance to stress corrosion cracking and fatigue, even in marine and chloride-rich environments. This is critical for long-term bolted connections in offshore and chemical plant service.
Non-Magnetic & Biocompatible
Titanium Grade 9 bolts are non-magnetic and biocompatible, making them suitable for MRI rooms, medical devices, and food processing equipment where contamination and magnetic interference must be avoided.

Titanium Grade 9 Bolts — Frequently Asked Questions

Browse expert answers to common questions about Titanium Grade 9 Bolts 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 bolts selection and pricing.
Titanium Grade 9 bolts are manufactured to DIN 931 (hex bolts, partial thread), DIN 933 (full thread), ISO 4014/4017, and ASME B18.2.1 (inch hex and heavy hex). Stud bolts are supplied per ASME B16.5 for flange connections. Custom thread forms (BSW, BSF, Whitworth) and special lengths are available on request.
Molybdenum-based or PTFE anti-seize is recommended for Titanium Grade 9 bolts to prevent galling and cold welding. Avoid copper or graphite-based compounds, as they can cause galvanic corrosion. Apply anti-seize to threads and bearing surfaces, and reduce torque by 20% for lubricated assembly.
Yes – Titanium Grade 9 bolts are highly resistant to pitting, crevice, and stress corrosion in seawater, even at elevated temperatures. They are widely specified for offshore, desalination, and marine hardware where stainless steel is prone to corrosion. No special coatings or cathodic protection are required.
Standard sizes (M8-M24) are available ex-stock with no formal MOQ – single pieces can be supplied for urgent repairs. Custom sizes or special threads typically require a 5 kg minimum order. Price breaks are available at 50, 200, and 500 pieces.
