Product Overview

What are Titanium Grade 12 Washers?

Titanium Grade 12 washers are corrosion-resistant fastener components manufactured from a titanium alloy containing 0.3% molybdenum and 0.8% nickel (UNS R53400). This alloy, conforming to ASTM B265 and ASTM B381, offers enhanced resistance to crevice corrosion and improved strength over commercially pure titanium grades. Titanium Grade 12 washers are widely specified for use in aggressive chemical environments, including hot brine, chlorides, and mildly reducing acids, where both mechanical durability and long-term corrosion resistance are critical.

With a minimum tensile strength of 483 MPa and excellent weldability, Titanium Grade 12 washers are the preferred choice for flange assemblies, pressure vessels, and heat exchangers in the chemical processing, desalination, and marine industries. Their unique alloying additions make them suitable for applications where Grade 2 or Grade 7 titanium would be insufficient.

Material Chemistry

Titanium Grade 12 Chemical Composition

Titanium Grade 12 Washers 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 Washers

Ni (0.6–0.9%) & Mo (0.2–0.4%) — Enhanced Corrosion Resistance
The addition of nickel and molybdenum to Titanium Grade 12 significantly improves resistance to crevice corrosion and stress corrosion cracking, especially in hot chloride and reducing acid environments. This makes Grade 12 washers ideal for use in brine, bleach, and chemical process piping.
Low Interstitials — High Ductility
Strict limits on carbon, nitrogen, and oxygen ensure high ductility and toughness, reducing the risk of brittle failure in bolted joints subject to vibration or thermal cycling.
Weldability & Fabrication
Grade 12’s composition allows for easy welding and forming, so washers can be custom-fabricated for non-standard flange assemblies without loss of corrosion resistance.

Industry Applications

Titanium Grade 12 Washers Applications — Industries & End Uses

Titanium Grade 12 Washers from RealBolt are specified across aerospace, marine, chemical processing, and medical devices where outstanding corrosion resistance and 900 MPa tensile strength are required for reliable fastener performance. Click each industry below for detailed application examples. Select an industry below to see specific Titanium Grade 12 washers application details and RealBolt stock availability.
Titanium Grade 12 washers are widely used in chemical process piping, heat exchangers, and reactor closures where resistance to hot chloride, hypochlorite, and reducing acid environments is essential. Their superior crevice corrosion resistance makes them ideal for flange assemblies in chlor-alkali and bleach plants.
Flat and spring washers for seawater intake structures, evaporator flange joints, and brine recirculation systems in MSF and RO desalination plants. Grade 12’s molybdenum and nickel additions prevent crevice attack in high-salinity, high-temperature service.
Washers for flue gas desulphurisation (FGD) absorber towers, ductwork, and heat exchanger connections where hot, acidic condensate and chlorides are present. Grade 12 washers maintain integrity and prevent bolt loosening in cycling thermal conditions.
Titanium Grade 12 washers are specified for marine pump flanges, seawater piping, and offshore platform structural connections where long-term resistance to pitting and crevice corrosion is required, even under submerged or splash-zone conditions.
