Product Overview

What are Titanium Grade 7 Nuts?

Titanium Grade 7 nuts are corrosion-resistant fasteners manufactured from titanium alloy stabilized with palladium (UNS R52400), conforming to ASTM B348 and ASTM B381. The addition of 0.12-0.25% Pd dramatically enhances resistance to reducing acids and chloride-rich environments, making these nuts the most corrosion-resistant titanium fasteners commercially available.

Titanium Grade 7 nuts are specified for critical chemical processing, desalination, and offshore applications where Grade 2 or Grade 5 titanium is insufficient. They are non-magnetic, lightweight, and maintain mechanical integrity in both oxidizing and reducing media, including wet chlorine gas and hydrochloric acid service.

Material Chemistry

Titanium Grade 7 Chemical Composition

Titanium Grade 7 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. Palladium content certified on MTC.

Why Titanium Grade 7 Alloy Composition Matters for Nuts

Palladium (0.12–0.25%) — Superior Corrosion Resistance
The addition of palladium to titanium creates a passive film that is highly resistant to reducing acids, including hydrochloric and sulfuric acid, and prevents crevice corrosion in chloride-rich environments. This makes Grade 7 nuts ideal for chemical processing and desalination plants.
Low Interstitials — Weldability & Ductility
Strict limits on oxygen, nitrogen, and carbon ensure excellent ductility and weldability, allowing Grade 7 nuts to be used in welded assemblies without embrittlement or loss of corrosion resistance.
Titanium Base — Lightweight & Non-Magnetic
Titanium’s low density and non-magnetic nature make these nuts suitable for sensitive instrumentation, MRI equipment, and weight-critical marine structures.

Titanium Grade 7 Nuts — Frequently Asked Questions

Browse expert answers to common questions about Titanium Grade 7 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 7 nuts selection and pricing.
Titanium Grade 7 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) are available on request. All nuts are supplied with full traceability and Pd content certification.
Use molybdenum-based or PTFE anti-seize compound (such as Molykote 1000 or Loctite LB 8014) on threads and bearing surfaces. Avoid copper-based or graphite-based anti-seize, as these can cause galvanic corrosion with titanium. Lubricated torque values should be reduced by 15-20% compared to dry assembly.
Yes – Titanium Grade 7 is specifically alloyed with palladium for superior resistance to reducing acids (including hydrochloric acid) and wet chlorine gas. These nuts are the preferred choice for chemical plants, bleach towers, and chlorine handling equipment where other titanium grades may fail.
