Product Overview

What are Titanium Grade 4 Studs?

Titanium Grade 4 studs are high-strength, commercially pure titanium fasteners manufactured from UNS R50700 bar stock conforming to ASTM B348. 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 studs are widely specified for critical bolted joints in chemical processing, marine, medical, and aerospace applications where high strength-to-weight ratio and biocompatibility are essential. Titanium Grade 4 studs are non-magnetic, exhibit outstanding resistance to crevice and pitting corrosion, and are suitable for both threaded and welded assemblies.

Material Chemistry

Titanium Grade 4 Chemical Composition

Titanium Grade 4 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
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 available on request.

Why Titanium Grade 4 Alloy Composition Matters for Studs

High Oxygen Content (0.30–0.40%) — Strength
The elevated oxygen content in Titanium Grade 4 increases its tensile and yield strength, making it the strongest of the commercially pure titanium grades. This is critical for stud bolts in high-pressure and load-bearing applications.
Low Interstitials — Corrosion Resistance
Strict limits on carbon, nitrogen, and hydrogen ensure excellent resistance to general, crevice, and pitting corrosion, even in aggressive chloride and oxidizing environments.
Biocompatibility
The absence of alloying elements like vanadium or aluminum makes Grade 4 titanium highly biocompatible, suitable for medical and pharmaceutical process equipment where contamination must be avoided.

Industry Applications

Titanium Grade 4 Studs Applications — Industries & End Uses

Titanium Grade 4 Studs 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 4 studs application details and RealBolt stock availability.
Titanium Grade 4 studs are specified for flange connections, riser systems, and subsea equipment in sour gas and seawater environments. Their immunity to chloride-induced stress corrosion cracking and hydrogen embrittlement makes them ideal for NORSOK and NACE MR0175 applications.
Studs for heat exchangers, pressure vessels, and piping in chlor-alkali, nitric acid, and desalination plants. Grade 4 titanium resists strong oxidizers and chlorides where stainless steel fasteners fail.
Used in bioreactors, cleanroom process piping, and medical device assembly due to their biocompatibility, non-magnetic nature, and resistance to sterilization chemicals.
Titanium Grade 4 studs are used in airframe structures, engine mounts, and satellite assemblies where high strength-to-weight ratio and corrosion resistance are critical. AMS 4921 specification.

Browse expert answers to common questions about Titanium Grade 4 Studs 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 4 studs selection and pricing.
Titanium Grade 4 stud bolts are available to DIN 976 (metric), ASME B16.5 (inch flange studs), ISO 898-1 (mechanical properties), and ASME B18.31.2 (continuous thread). Custom thread forms (BSW, BSF, Whitworth) and lengths are available on request with typical lead times of 2-3 weeks.
Molybdenum-based anti-seize (such as Molykote 1000 or Loctite LB 8012) is recommended for Titanium Grade 4 studs to prevent galling and seizing. Avoid copper-based or graphite-based compounds to prevent galvanic corrosion. Apply to threads and nut bearing faces; reduce torque by 20% for lubricated assembly.
Yes – Titanium Grade 4 is completely resistant to pitting, crevice, and stress corrosion in seawater, even at elevated temperatures. It is the preferred choice for marine, desalination, and offshore oil & gas applications where long-term durability is required without coatings or cathodic protection.
No formal MOQ for standard sizes (M8-M36) held ex-stock – we supply from single pieces for urgent requirements. Custom sizes or non-standard threads typically require a 5 kg minimum. Price breaks are available at 25 pcs, 100 pcs, and 250 pcs.
