ASTM B338 Gr7 Titanium Pipes & Tubes
GNEE is a leading supplier of ASTM B338 Grade 7 titanium tubing. Due to the limitations of stainless steel and other materials in specific environments, titanium tubing is increasingly used in a wide range of applications. Titanium tubing is a common rolled steel product, renowned for its excellent corrosion resistance and superior strength-to-weight ratio, making it ideal for numerous products and industries. The development of various titanium alloys further expands its applications in industrial, chemical processing, and power generation sectors. The American Society of Mechanical Engineers (ASME) has approved a variety of titanium grades, providing a wide range of choices for different projects. While grades 1, 2, 3, 7, 9, and 11 are available, Grade 7 titanium tubing is favored in most applications due to its availability and suitability for rapid production and high-volume orders.
When selecting a titanium grade, determining the specific application requirements is crucial. For applications requiring higher corrosion resistance, Grades 7, 12, 16, or 26 titanium tubing are ideal. For applications with higher strength requirements, Grades 3 and 12 may be more suitable.
