Product Overview

What are Titanium Grade 4 Threaded Rods?

Titanium Grade 4 threaded rods are high-strength, commercially pure titanium fasteners manufactured from UNS R50700 bar stock in accordance with ASTM B348 and ASTM F67. Grade 4 is the strongest of the commercially pure titanium grades, offering a minimum tensile strength of 550 MPa and excellent corrosion resistance in oxidizing and chloride-rich environments.

These threaded rods are widely specified for critical bolted joints in chemical processing, marine, medical, and aerospace applications where high strength-to-weight ratio, biocompatibility, and immunity to crevice and pitting corrosion are essential. Titanium Grade 4 threaded rods are non-magnetic, non-toxic, and maintain mechanical integrity at elevated temperatures up to 400°C.

Material Chemistry

Titanium Grade 4 Chemical Composition

Titanium Grade 4 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.

Chemical Composition per ASTM B348

ElementComposition (%)
Titanium (Ti)Balance
Oxygen (O)0.30-0.40
Iron (Fe)0.50 max
Carbon (C)0.08 max
Nitrogen (N)0.05 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. PMI and oxygen content reports available on request.

Why Titanium Grade 4 Alloy Composition Matters for Threaded Rods

High Oxygen Content (0.30–0.40%) — Strength
The elevated oxygen content in Grade 4 titanium increases tensile and yield strength, making these threaded rods suitable for high-load bolted joints in aggressive environments.
Low Iron, Carbon, Nitrogen — Corrosion Resistance
Strict limits on Fe, C, and N ensure maximum resistance to crevice, pitting, and stress corrosion cracking, even in chloride and oxidizing media.
Biocompatibility
Grade 4 titanium is non-toxic and non-magnetic, making it ideal for medical, dental, and food processing threaded rod applications.

Industry Applications

Titanium Grade 4 Threaded Rods Applications — Industries & End Uses

Titanium Grade 4 Threaded Rods 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.
Titanium Grade 4 threaded rods are specified for bolted joints in chlorine, hypochlorite, and caustic soda plants, where stainless steel fasteners fail due to rapid pitting and crevice corrosion. Used in heat exchanger tube sheets, reactor closures, and filter press assemblies.
Ideal for seawater-exposed structures, desalination plants, and shipbuilding, these rods provide long-term resistance to biofouling and corrosion in splash zones, hull penetrations, and deck equipment. Non-magnetic and lightweight for naval applications.
Used in autoclave frames, cleanroom assemblies, and surgical device supports, Titanium Grade 4 threaded rods offer biocompatibility, non-toxicity, and resistance to repeated sterilization cycles. Supplied per ASTM F67 for implantable and non-implantable hardware.
Titanium Grade 4 rods are used in aircraft structural assemblies, satellite payload supports, and missile components where high strength-to-weight ratio, fatigue resistance, and non-magnetic properties are critical. Qualified to AMS 4901 and ASTM B348.
