Product Overview

What are Titanium Grade 12 Screws?

Titanium Grade 12 screws are high-performance 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 corrosion resistance, especially in mildly reducing and oxidizing environments, and offers enhanced strength compared to commercially pure titanium grades.

Conforming to ASTM B348 and ASTM F467, Titanium Grade 12 screws are widely specified for critical applications in chemical processing, desalination, and marine environments where resistance to crevice corrosion, stress corrosion cracking, and high-temperature oxidation is essential. Their excellent weldability and formability make them a preferred choice for demanding bolted assemblies.

Material Chemistry

Titanium Grade 12 Chemical Composition

Titanium Grade 12 Screws 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.

Why Titanium Grade 12 Alloy Composition Matters for Screws

Nickel & Molybdenum — Enhanced Corrosion Resistance
The addition of nickel and molybdenum in Titanium Grade 12 significantly improves resistance to crevice corrosion and stress corrosion cracking, especially in hot brines, chlorides, and mildly reducing acids. This makes these screws ideal for chemical processing and marine environments.
Superior Weldability
Titanium Grade 12 screws can be welded without risk of embrittlement, maintaining their corrosion resistance and mechanical properties in the heat-affected zone. This is critical for pressure vessel and piping assemblies.
High-Temperature Stability
The alloy’s composition allows for continuous service up to 315°C, outperforming commercially pure titanium in oxidizing and mildly reducing environments.
