Product Overview

What are Titanium Grade 1 Studs?

Titanium Grade 1 studs are high-purity, commercially pure titanium fasteners manufactured from UNS R50250 bar stock in accordance with ASTM B348 and ASTM F67. As the softest and most ductile of all titanium grades, Grade 1 offers exceptional corrosion resistance, outstanding formability, and a minimum tensile strength of 240 MPa. These studs are non-magnetic, lightweight, and biocompatible, making them ideal for critical applications in chemical processing, marine, and medical industries where both corrosion resistance and low weight are essential.

Titanium Grade 1 studs are specified for use in highly corrosive environments, including chlorinated media, seawater, and oxidizing acids. Their low iron and oxygen content ensures maximum ductility and weldability, making them suitable for custom fabrication and assembly in demanding service conditions.

Material Chemistry

Titanium Grade 1 Chemical Composition

Titanium Grade 1 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
Iron (Fe)0.20% max
Oxygen (O)0.18% max
Carbon (C)0.08% max
Nitrogen (N)0.03% 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 1 Alloy Composition Matters for Studs

Ultra-Low Oxygen & Iron — Maximum Ductility
Grade 1 titanium’s low oxygen (=0.18%) and iron (=0.20%) content ensures the highest ductility and formability among all titanium grades, allowing for easy installation, cold forming, and reliable sealing in flange assemblies.
No Alloying Elements — Pure Corrosion Resistance
With no intentional alloying additions, Titanium Grade 1 offers outstanding resistance to chlorides, seawater, and oxidizing acids, making it ideal for chemical plant and marine fastener applications.
Biocompatibility
The absence of toxic elements and high purity make Grade 1 titanium studs suitable for medical and pharmaceutical equipment, where biocompatibility and non-reactivity are essential.

Titanium Grade 1 studs are available to DIN 976 (full thread), DIN 975 (threaded rod), ASME B16.5 (flange studs), and ASME B18.31.2 (inch continuous thread). Custom thread forms (UNC, UNF, BSW, BSP) and lengths are available on request with typical lead times of 2-3 weeks.
Use PTFE-based or molybdenum disulfide anti-seize compounds on Titanium Grade 1 studs to prevent galling and facilitate disassembly. Avoid copper-based or graphite-based anti-seize, as these can cause galvanic corrosion with titanium in wet or marine environments.
Yes – Titanium Grade 1 is completely resistant to pitting, crevice, and stress corrosion in seawater, even at elevated temperatures. It is the preferred material for marine and desalination plant fasteners, requiring no special coatings or cathodic protection.
No formal MOQ for standard metric sizes (M8-M36) held in stock – single pieces can be supplied for urgent maintenance. Custom sizes or inch threads typically require a 5 kg minimum. Price breaks are available at 25, 100, and 500 pieces.
