Product Overview

What are Titanium Grade 1 Screws?

Titanium Grade 1 screws are precision fasteners manufactured from commercially pure titanium (UNS R50250), conforming to ASTM B348 and ASTM F67 standards. As the softest and most ductile of all titanium grades, Grade 1 offers exceptional corrosion resistance, outstanding formability, and high impact toughness, making it ideal for critical fastening applications in aggressive environments.

These screws are non-magnetic, biocompatible, and exhibit excellent resistance to chlorides, seawater, and a wide range of acids. Titanium Grade 1 screws are widely specified for chemical processing, marine, medical, and aerospace assemblies where both strength and corrosion resistance are paramount.

Material Chemistry

Titanium Grade 1 Chemical Composition

Titanium Grade 1 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.

Chemical Composition per ASTM B348

ElementComposition (%)
Titanium (Ti)Balance
Iron (Fe)0.20% max
Oxygen (O)0.18% 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 1 Alloy Composition Matters for Screws

Ultra-Low Interstitials — Ductility & Weldability
The extremely low levels of oxygen, nitrogen, and carbon in Titanium Grade 1 ensure maximum ductility and weldability, making these screws ideal for critical assemblies and custom fabrication.
Iron Content — Corrosion Resistance
With iron limited to 0.20% max, Grade 1 titanium screws offer superior resistance to crevice, pitting, and general corrosion in chloride-rich and marine environments.
Biocompatibility — Medical & Food Applications
The absence of alloying elements and extremely low impurity levels make Titanium Grade 1 screws fully biocompatible and suitable for medical, dental, and food processing equipment.
