Products Description
Titanium tubing is finding increasing use in a wide range of applications due to the inefficiencies of stainless steel and other materials in many situations. One of the most common titanium rolled products is titanium tubing, used in a wide range of applications due to its excellent corrosion resistance and high specific strength. The development of a wide range of alloys has expanded titanium's applications in industries such as industrial, chemical processing, and power generation.
The American Society of Mechanical Engineers has approved most titanium alloy grades, providing a wider range of options for various projects. While grades 1, 2, 3, 7, 9, and 11 are all acceptable, grade 7 is the most suitable material in most cases. Its availability makes it a preferred material for quick production runs and large orders.
Before selecting any grade, it is crucial to determine its specific application. Grades 7, 12, 16, or 26 can be used to manufacture titanium tubing for applications requiring higher corrosion resistance. For pipes requiring higher strength, grades 3 and 12 may be better materials.
