Product Description
Grade 4 Titanium Bar ASTM B348 For Hydraulic and Instrumentation Tubing
The Grade 4 Titanium Bar is characterized by its dimensions and adherence to a specific standard. The diameter of the bar ranges from 6.35 millimeters to 200 millimeters, offering a variety of sizes to accommodate different applications. The maximum length of the bar can extend up to 6000 millimeters. This titanium bar conforms to the ASTM B348 standard, which ensures consistent quality and properties for industrial uses. The surface of the bar is polished, providing a smooth finish that is often required for precision engineering and aesthetic purposes.
What Is Grade 4 Titanium Bar
Grade 4 Titanium Bar stands as the strongest among pure grades of titanium, owing its superior strength to high oxygen content and extra high strength. It successfully marries excellent corrosion resistance with good formability and weldability, making it a versatile material for various applications. Primarily, Grade 4 titanium bar is utilized in the creation of hydraulic and instrumentation tubing. Its corrosion-resistant properties make it an ideal choice for a broad range of chemical processing equipment, along with marine and airframe applications. The Grade 4 titanium bar can be used for components that require strength up to temperatures of 400°F (204°C), and it offers oxidation resistance up to 600°F (315°C).

In recent years, the use of Grade 4 Titanium Bar has become increasingly prevalent, particularly for medical applications. It is important to note that while the material standard for medical use is designated as ASTM F67, the industrial standard for Grade 4 titanium bar is identified by ASTM B348. Additionally, Grade 4 titanium material is known by other designations such as UNS R50700 and DIN 3.7065.
The dimensions of the Grade 4 titanium bar, including its diameter and length, can be customized to meet specific requirements, with the possibility of a tolerance level as precise as H8. This adaptability in size allows for the material to be tailored for a variety of uses.
Recognized as the strongest among commercially pure forms of titanium, Grade 4 titanium bar exhibits excellent corrosion resistance across a broad spectrum of environments. Its superior strength makes it an ideal choice for applications demanding high durability. As such, it is widely used in industrial settings, medical devices, and aerospace engineering where the combination of high strength and corrosion resistance is crucial.
