This document explains how to use the specification ASTM B381 chemical composition and mechanical properties, as well as the kinds, and uses of titanium flanges Grade 5.
What are ASTM B381 Grade 5 Titanium Flanges?
ASTM B381 is a standard that encompasses forging titanium and other titanium alloy components that find application in most rigorous industrial applications. Grade 5 titanium is also referred to in the form of Ti-6Al-4V is an alpha beta titanium metal that has about 66% vanadium and 4% aluminum.
This alloy provides an outstanding combination of strength as well as corrosion resistance and heat resistance which makes it perfect for the most demanding pipeline systems.
Flanges made of Grade 5 Titanium can be used to join pipes as well as valves, pumps and other equipment within the pipe system. The forged flanges are solid and leak-proof joints by using gaskets and bolts.
The most important characteristics are:
- High strength-to-weight ratio
- Excellent corrosion resistance
- Superior resistance to fatigue
- High temperature tolerance
- Good weldability and fabrication characteristics
With these attributes industry sectors rely in the Grade five Titanium Flanges manufacturers to supply robust piping components that are essential for processes.

As a top Titanium Flanges supplier from India, Jaysteelcorporation manufactures ASTM B381 Flanges in accordance with international quality standards.
Chemical Composition of Grade 5 Titanium Flanges
The titanium grade 5 alloy is a well-balanced mix of vanadium and aluminum, which greatly enhances its mechanical properties.
Common compositions:
| Element | Percentage |
| Titanium | Balance |
| Aluminum | 5.5 – 6.75% |
| Vanadium | 3.5 – 4.5% |
| Iron | <= 0.25% |
| Oxygen | <= 0.20% |
| Carbon | <= 0.08% |
It stabilizes and protects the Alpha phase while vanadium stabilizes beta phase, which gives the alloy greater durability and strength.
This unique combination is what makes Grade 5 titanium the most popular titanium alloys around the world.
Mechanical Properties of ASTM B381 Grade 5
The strength of the Titanium Grade 5 flanges allows them to be used for high-temperature and high-pressure applications.
Mechanical properties typical of a mechanical device:
- Tensile Strength: ~950-980 MPa
- Yield Strength: ~880 MPa
- Elongation: ~14%
These properties include:
- Great load-bearing capability
- The resistance to stress caused by mechanical forces
- Long service life for critical pipes systems
This is the reason that numerous industries choose forging titanium pipe Flanges over other types of materials such like stainless steel.
Types of ASTM B381 Grade 5 Titanium Flanges
A variety of flanges is available based on the pipe use.
1. Weld Neck Flanges
The flanges have a tapered hub, which provides sturdy reinforcement. They are typically employed in pipelines with high pressure.
2. Slip-On Flanges
Slip-on flanges slide across the pipe, and are welded both on the inside and outside. They are simple to set up and are cost-effective.
3. Blind Flanges
Blind Flanges are used to seal the pipe or pressure vessel.
4. Socket Weld Flanges
These flanges are made to be used in pipelines of small diameter in which welding is a safe connection.
5. Threaded Flanges
Flanges with threads are utilized when welding isn’t possible which allows the flange to be screwed directly into the pipe.
Other variations are:
- Lap joint flanges
- Ring-type joint (RTJ) Flanges
- Flanges for Spectacle Blinds
The most reliable Grade 5 Titanium Flanges Suppliers can provide these options to satisfy a wide range of industrial requirements.
