Titanium threaded rods are best known for being strong, lightweight and corrosion resistant. One property that stands out when compared to other metal threaded rods is that titanium threaded rods 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 threaded rods ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods.
Titanium threaded rods are also unique among metals in the chemical processing industry for handling chlorine (wet) and chlorine compounds in aqueous solutions. Titanium threaded rods are fully resistant to solutions of chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. As a result titanium threaded rods are often using within the chlorine related industries such as pulp and paper and chlor-alkali / bleach.
Titanium threaded rods are also an excellent material to prevent seawater corrosion. Because titanium threaded rods 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 threaded rods are used throughout the oil & gas, desalination and marine industries.
The most common grades of Titanium threaded rods 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, Werkstoff 3.7035
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, Werkstoff 3.7165
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, Werkstoff 3.7235
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
