Unique for its strength, lightness of weight and corrosion resistance

Titanium bolts are best known for being strong, lightweight and corrosion resistant. One property that stands out when compared to other metal bolts is that titanium bolts have the highest strength-to-weight ratio with a density of 4.51 g /cm3. As an example, titanium grade 5 is 4 times stronger than 316 stainless steel at nearly half the weight. This makes titanium bolts ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods. 

Titanium bolts are also unique among metals in the chemical processing industry for handling chlorine (wet) and chlorine compounds in aqueous solutions. Titanium bolts are fully resistant to solutions of chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. As a result titanium bolts are often using within the chlorine related industries such as pulp and paper and chlor-alkali / bleach.

Titanium bolts are also an excellent material to prevent seawater corrosion. Because titanium bolts can resists corrosion by seawater up to temperatures as high as 500°F (260°C) as well as survive at ocean depths over a mile below the surface, titanium bolts are used throughout the oil & gas, desalination and marine industries.

The most common grades of Titanium fasteners and flanges are Grade 2 and Grade 5. Gain more insight on these by accessing our Grade 2 and Grade 5 overviews or by contacting our engineering experts.

Titanium Grades, Chemistry & Specifications

Titanium Grade 2  (Commercially Pure)

Unalloyed titanium; Commercially pure titanium is the most common grade of titanium utilized throughout industry due to its ease of availability and good properties.

Titanium Grade 2 Specifications: UNS R50400,  ASTM B 348,  AMS 4921, ASTM F 67, ISO 5832-2

Titanium Grade 2 Chemistry

Titanium Grade 5 (Ti 6Al-4V)

Known as the “workhorse” of the titanium alloys, Ti 6Al-4V, or Grade 5 titanium, is 2x stronger than titanium grade 2. This alloy offers high strength and light weight, useful formability and high corrosion resistance. Ti 6AI-4V finds many uses in the aerospace, medical, marine and chemical processing industries.

Titanium Grade 5 Specifications:  ASTM - B265, B348, B381, B861, F467 and F468, AMS - 4911, 4928, 4935, 4965 and 4967, MIL-T - 9046 and - 9047

Titanium Grade 5 Chemistry

Titanium Grade 7 

Grade 7 is the most corrosion resistant of all titanium alloys and is typically used in chemical processes and production equipment components. Similar to Grade 2, but with the addition of 0.12 to 0.25% palladium, Grade 23 has enhanced corrosion resistance to reducing acids and localized attack in hot halides. 

Titanium Grade 7 Specifications: ASTM - B265, B337, B338, B348, B363, B381, B861 and B862

Titanium Grade 7 Chemistry

Titanium Grade 23 (TI 6AL-4V ELI)

Titanium grade 23 or TI 6AL-4V ELI is an Extra Low Intersticial grade. This grade is similar to Grade 5, but because of the low intersticials, its mechanical properties are enhanced. This ELI grade is often found in more demanding medical device applications as well as industrial applications.

Titanium Grade 23 Specifications: 

ASTM - B265, B348, B363, B381, B861, B862 andF136, AMS - 4907, 4930 and 4956
