Product Overview

What are Titanium Grade 2 Bolts?

Titanium Grade 2 bolts are commercially pure titanium fasteners manufactured from UNS R50400 bar stock in accordance with ASTM B348 and ASTM F67. Renowned for their exceptional corrosion resistance, low density, and high strength-to-weight ratio, these bolts are widely specified in critical applications where both mechanical performance and biocompatibility are required.

Titanium Grade 2 bolts are non-magnetic, offer excellent resistance to seawater and a broad range of acids, and maintain their mechanical properties up to 400°C. They are the preferred choice for marine, chemical processing, medical, and aerospace bolted connections where stainless steel or nickel alloys may not suffice.

Material Chemistry

Titanium Grade 2 Chemical Composition

Titanium Grade 2 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
Iron (Fe)0.30% max
Oxygen (O)0.25% 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. Biocompatibility and PMI available on request.

Why Titanium Grade 2 Alloy Composition Matters for Bolts

Commercially Pure Titanium — Corrosion Resistance
Titanium Grade 2’s high purity and low interstitial content provide outstanding resistance to seawater, chlorides, and oxidizing acids, making it ideal for marine and chemical process bolting.
Low Iron & Oxygen — Ductility & Weldability
Strict limits on Fe and O ensure excellent ductility and weldability, allowing Titanium Grade 2 bolts to be fabricated and installed without embrittlement or loss of corrosion resistance.
Biocompatibility
The absence of toxic alloying elements makes Titanium Grade 2 bolts suitable for medical implants and food processing equipment, where biocompatibility and non-reactivity are essential.

Titanium Grade 2 hex bolts are available to DIN 931 (metric partial thread), DIN 933 (metric full thread), ISO 4014/4017, and ASME B18.2.1 (inch hex and heavy hex). Stud bolts are supplied per ASME B16.5 or MSS SP-75 for flange applications. Custom thread forms (BSW, BSF, Whitworth, BSPP) are available on request with 2-3 week lead time.
PTFE-based or molybdenum disulfide anti-seize is recommended for Titanium Grade 2 bolts to prevent galling and facilitate disassembly. Avoid copper-based or graphite-based anti-seize, as these can cause galvanic corrosion with titanium. Apply a thin, even layer to threads and bearing surfaces.
Yes – Titanium Grade 2 bolts are completely resistant to seawater corrosion and are biocompatible, making them ideal for marine, desalination, and medical implant applications. They are certified to ISO 5832-2 for surgical use and are widely used in critical environments where stainless steel is inadequate.
