Product Overview

What are Titanium Grade 12 Bolts?

Titanium Grade 12 bolts are high-performance fasteners manufactured from a titanium alloy containing 0.3% molybdenum and 0.8% nickel (UNS R53400), conforming to ASTM B348 and ASTM B381. This alloy offers superior corrosion resistance compared to commercially pure titanium, especially in mildly reducing and oxidizing environments, and is known for its excellent weldability and moderate strength.

Titanium Grade 12 bolts are widely specified for chemical processing, desalination, and marine applications where resistance to crevice corrosion, stress corrosion cracking, and pitting is critical. Their unique combination of strength, ductility, and corrosion resistance makes them ideal for demanding bolted connections in aggressive environments.

Material Chemistry

Titanium Grade 12 Chemical Composition

Titanium Grade 12 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

Molybdenum (Mo)0.2-0.4

? All heats verified by NABL-accredited spectrometry. PMI and interstitial analysis available on request.

Why Titanium Grade 12 Alloy Composition Matters for Bolts

Ni (0.6–0.9%) & Mo (0.2–0.4%) — Enhanced Corrosion Resistance
The addition of nickel and molybdenum to Titanium Grade 12 significantly improves resistance to crevice corrosion and stress corrosion cracking, especially in hot brines, chlorides, and mildly reducing acids. This makes Grade 12 bolts ideal for chemical processing and marine environments.
Superior Weldability
Titanium Grade 12 bolts can be welded without risk of embrittlement or loss of corrosion resistance, making them suitable for critical pressure vessel and piping assemblies.
Low Interstitial Content
Strict control of carbon, nitrogen, oxygen, and hydrogen ensures high ductility and toughness, reducing the risk of brittle failure in bolted joints under dynamic loads.
