Product Overview

What are Titanium Grade 1 Nuts?

Titanium Grade 1 nuts are precision fasteners manufactured from commercially pure titanium 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 a high strength-to-weight ratio. These nuts are non-magnetic, biocompatible, and ideal for applications where maximum corrosion resistance is required in low to moderate strength assemblies.

Titanium Grade 1 nuts are widely specified for use in chemical processing, desalination, marine, and medical equipment due to their ability to withstand aggressive environments, including chlorides and oxidizing acids, without suffering from crevice or pitting corrosion. All nuts are supplied with full traceability and EN 10204 3.1 certification.

Material Chemistry

Titanium Grade 1 Chemical Composition

Titanium Grade 1 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 available on request.

Why Titanium Grade 1 Alloy Composition Matters for Nuts

Ultra-Low Interstitials — Maximum Ductility
The extremely low levels of oxygen, nitrogen, and carbon in Titanium Grade 1 ensure the highest ductility and formability among all titanium grades, making these nuts ideal for applications requiring cold forming or repeated assembly/disassembly.
Iron Content — Corrosion Resistance
With iron limited to 0.20%, Grade 1 titanium nuts maintain superior resistance to general, crevice, and pitting corrosion in both oxidizing and reducing environments, including seawater and chlorinated media.
Biocompatibility
The absence of alloying elements and extremely low impurity levels make Titanium Grade 1 nuts fully biocompatible, suitable for medical and pharmaceutical equipment where metal ion release must be minimized.

Titanium Grade 1 Nuts — Frequently Asked Questions

Browse expert answers to common questions about Titanium Grade 1 Nuts from RealBolt — covering grade selection, ASTM B348/F467, seawater immunity, weight saving, galling precautions, and certification. Contact our technical team directly for project-specific guidance on Titanium Grade 1 nuts selection and pricing.
Titanium Grade 1 nuts are available to DIN 934 (metric hex), ISO 4032, ASME B18.2.2 (inch hex and heavy hex), and DIN 985 (nyloc/lock nuts). Prevailing torque and custom thread forms (UNC, UNF, BSW, BSF) are available on request. Special geometries and thin nuts can be supplied with short lead times.
Use PTFE-based or molybdenum-based anti-seize compound (such as Molykote 1000 or Loctite LB 8014) on threads and bearing surfaces. This prevents galling and ensures consistent torque. Avoid copper-based anti-seize, as it may cause galvanic corrosion with titanium in wet environments.
Yes – Titanium Grade 1 nuts are completely resistant to pitting, crevice, and stress corrosion cracking in seawater, even at elevated temperatures. They are widely used in desalination, offshore, and marine structures without the need for coatings or cathodic protection.
No MOQ for standard metric sizes (M6-M24) held in stock – we supply from single pieces for urgent requirements. Custom sizes or special threads have an MOQ of 5 kg. Price breaks are available at 50 pcs, 200 pcs, and 500 pcs for project orders.
