Product Overview

What are Titanium Grade 12 Nuts?

Titanium Grade 12 nuts are corrosion-resistant fasteners manufactured from a titanium alloy containing small additions of nickel (0.6-0.9%) and molybdenum (0.2-0.4%), designated as UNS R53400. This alloy is known for its superior resistance to crevice corrosion and stress corrosion cracking, especially in mildly reducing and oxidizing environments, such as hot brines and chlorinated media.

Conforming to ASTM B348 and ASTM B381, Titanium Grade 12 nuts are widely specified for critical bolted joints in chemical processing, desalination, and offshore oil & gas installations. Their mechanical strength is comparable to Grade 2 titanium, but with enhanced corrosion performance, making them ideal for flange connections, pressure vessels, and heat exchanger assemblies exposed to aggressive media.

Material Chemistry

Titanium Grade 12 Chemical Composition

Titanium Grade 12 Nuts 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.

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

Why Titanium Grade 12 Alloy Composition Matters for Nuts

Ni + Mo — Enhanced Crevice & SCC Resistance
The addition of nickel and molybdenum to Titanium Grade 12 significantly improves resistance to crevice corrosion and stress corrosion cracking, especially in hot chloride and mildly reducing environments. This is critical for nuts used in seawater, brine, and chemical plant service.
Low Interstitials — High Ductility
Strict control of carbon, nitrogen, and oxygen ensures high ductility and toughness, reducing the risk of brittle failure in bolted joints under dynamic loading or thermal cycling.
Weldability & Fabrication
Titanium Grade 12 nuts can be welded to titanium piping and flanges without risk of embrittlement, making them ideal for process plant construction and repair.

Industry Applications

Titanium Grade 12 Nuts Applications — Industries & End Uses

Titanium Grade 12 Nuts 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 12 nuts application details and RealBolt stock availability.
Titanium Grade 12 nuts are widely used for flange joints, vessel closures, and piping connections in chlor-alkali, bleach, and hypochlorite production plants. Their resistance to crevice corrosion and stress corrosion cracking in hot chloride and oxidizing media makes them the preferred choice over stainless steel or lower grades of titanium.
Hex nuts and lock nuts for seawater desalination plants, brine concentrators, and evaporators. Grade 12’s enhanced resistance to hot brine and chloride pitting ensures long-term reliability in critical bolted joints exposed to aggressive saline environments.
Titanium Grade 12 nuts are specified for subsea pipeline flanges, riser connections, and topside process equipment where resistance to both seawater and sour gas (H2S) is required. Their mechanical strength and corrosion resistance meet NORSOK and major oil company specifications.
Used in condenser and heat exchanger assemblies, FGD scrubbers, and cooling water systems in power plants. Grade 12 nuts prevent crevice corrosion and galling in high-temperature, chloride-rich service, outperforming stainless steel fasteners.

Titanium Grade 12 hex nuts are available to DIN 934 (metric), ISO 4032, and ASME B18.2.2 (inch hex and heavy hex). Lock nuts are supplied per DIN 985 and ISO 7040. Custom thread forms (UNC, UNF, BSW) and prevailing torque types are available on request with typical lead times of 2-3 weeks.
Use a titanium-compatible anti-seize compound such as Molykote P-37 or Jet-Lube 550 Extreme. Apply to threads and nut bearing surfaces to prevent galling. Avoid copper-based or graphite-based anti-seize, as these can cause galvanic corrosion with titanium alloys. Lubricated torque values should be reduced by 15-20% compared to dry assembly.
Yes – Titanium Grade 12 nuts offer outstanding resistance to crevice corrosion, pitting, and stress corrosion cracking in hot brine, seawater, and chloride-rich environments. They are specified for desalination, offshore, and chemical plant service where stainless steel or lower titanium grades are inadequate.
