Materials and standard of titanium flat bar stock

Titanium flat bar stock Materials

Ti-6Al-4V (ASTM B348): This is the most common titanium alloy used for flat bar stock, accounting for over 70% of all titanium flat bar stock used worldwide. It has a good balance of strength, corrosion resistance, and formability.

Ti-6Al-2Sn-4Zr-6Mo (ASTM B348): This alloy is known for its excellent high-temperature properties, making it ideal for applications that operate in hot environments.

Ti-6Al-4V ELI (Extra Low Interstitial) (ASTM B348): This grade of Ti-6Al-4V has been heat treated to reduce the amount of interstitial elements, such as oxygen and nitrogen, which can affect its properties. This makes it more formable and weldable than standard Ti-6Al-4V.

Ti-3Al-2.5V (ASTM B265): This alloy has excellent corrosion resistance in saltwater, making it ideal for marine applications.

Ti-5Al-2.5Sn (ASTM B523): This alloy has good strength and formability, making it a good choice for structural components.

Titanium flat bar stock Standards

ASTM B265 (General Requirements for Wrought Titanium and Titanium Alloy Products)

AMS 4935 (Titanium Sheet, Plate, and Strip for Aircraft Structures)

MIL-T-9046D (Titanium Sheet, Plate, and Strip for Aircraft Structures)

AMS 7899 (Titanium Billets and Bars for Aerospace Applications)

ASTM B348 (Titanium Billets, Bars, Forgings, and Extrusions)

In addition to these standard grades, there are a number of specialty titanium grades available for applications with specific requirements, such as high strength, high temperature resistance, or improved corrosion resistance.
