Titanium studs are best known for being strong, lightweight and corrosion resistant. One property that stands out when compared to other metal studs is that titanium studs 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 studs ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods.

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

Titanium studs are also an excellent material to prevent seawater corrosion. Because titanium studs 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 studs are used throughout the oil & gas, desalination and marine industries.

The most common grades of Titanium studs 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. In addition to common threaded studs, we also offer Titanium weld studs. This specialty fastener provides a secure, cross-sectional weld in single-sided access situations. Titanium weld studs are available in a variety of fastener styles.

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, ASTM F467 (Nuts), ASTM F468 (Bolts, Screws, Studs)

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, Werkstoff 3.7165, ASTM F467 (Nuts), ASTM F468 (Bolts, Screws, Studs)

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, Werkstoff 3.7235, ASTM F467 (Nuts), ASTM F468 (Bolts, Screws, Studs)

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, ASTM F467 (Nuts), ASTM F468 (Bolts, Screws, Studs)

Titanium Set Screw Features & Benefits

Titanium set screws are unique in that they have no screw head, meaning that they have no protruding part past the threaded shaft. They are thread only and are available with a socket or slotted driver insert at one end. Set screws are used to secure an object within or against another object. Typically they secure a rotating part such as a gear or shaft. Titanium set screws are driven through a threaded hole in the rotating part until it is tight against the inner object, preventing from moving relative to the outer object. Set screws are available with various points depending on the application.

cup point

Cup Point
This is the most commonly used set screw and is identified by a cup-shaped indentation on one end. Titanium cup points are typically used for a quick, semi-permanent or permanent applications where it is acceptable to cut the cup point edge of the screw.

Cone Point
A cone point is easily identifiable by its sharp cone-shaped point – just like an ice cream cone. Titanium cone point set screws deliver the strongest clamping force due to the deep penetration of the point. As a result they are used for permanent assembly.

Flat Point

The cheapest and simplest of the set screw point styles, this screw has a flat surface on the bottom of the screw. This type is used when you need the ability to frequently change parts and require minimal shaft deformation.
