About

Titanium Grade 2 bolts are lightweight, corrosion-resistant fasteners made from commercially pure titanium (UNS R50400). They are widely used in aerospace, marine, chemical, and medical industries due to their excellent strength-to-weight ratio, biocompatibility, and resistance to seawater and chemical environments.

Key Specifications of Titanium Grade 2 Bolts

• Material: Commercially pure titanium (Grade 2, UNS R50400, ASTM B348).
• Density: 4.51 g/cm (about 60% lighter than steel).
• Tensile Strength: 345 MPa.
• Yield Strength: 275 MPa.
• Hardness: 160 HB.
• Corrosion Resistance: Excellent in oxidizing and mildly reducing environments, seawater, and chlorides.
• Workability: Good formability, weldability, and ductility.

Common Uses

• Aerospace: Aircraft structures, engine components, and fasteners where weight reduction is critical.
• Marine: Shipbuilding, offshore platforms, and subsea equipment (resists seawater corrosion).
• Chemical Processing: Heat exchangers, reactors, and piping systems exposed to corrosive chemicals.
• Medical: Surgical implants, orthopedic devices, and dental applications (biocompatible and non-toxic).
• Automotive & Motorsport: High-performance vehicles requiring lightweight yet strong fasteners.

Why Choose Titanium Grade 2 Bolts?

• Lightweight yet durable reduces structural weight without compromising strength.
• Superior corrosion resistance ideal for seawater and chemical exposure.
• Biocompatible safe for medical and dental applications.
• Long service life minimal maintenance and replacement needs.
• Excellent weldability and ductility easy to fabricate and install.

Exceptional Corrosion and Chemical Resistance

Titanium Grade 2 bolts provide superior resistance against corrosion in harsh environments, including seawater, chlorides, acids, and alkalis. This makes them highly reliable for use in marine, chemical, and industrial sectors, ensuring longevity even in aggressive settings. Their stable oxide layer protects the underlying metal, reducing maintenance costs and prolonging service life.


Consistent Mechanical Performance

With a tensile strength of approximately 344 MPa and a yield strength of 275 MPa, Titanium Grade 2 bolts ensure robust fastening. Their high elongation (20% or higher) and hardness (Rockwell B70 max) provide an excellent balance between strength and ductility, suitable for high-stress environments like aerospace and defense.


Versatile Applications & Customization

These bolts are available in metric, UNC, or UNF threads, with various head styles and customizable sizes to comply with international standards (ASTM B348, ASME SB348, DIN, ISO, BS). Suitable for standard or unique specifications, they meet the demands of diverse industries with mill test certificates and optional third-party inspections.
