Astm B338 Gr2 Titanium Seamless Tube

The minimum titanium content of Astm B338 Gr2 Titanium Seamless Tube ranges from approximately 98.925% to 99.5% by weight.ASTM B338 Gr. 2 titanium tubing is primarily used in the manufacture of surface condensers, evaporators, and heat exchangers. These applications typically require excellent corrosion resistance as well as high fabrication ductility with relatively low in-service strength. These titanium tubes can be further processed into spirals, U-tubes, serpentine tubes, concentric coils, and other specialized shapes.

ASTM B338 Grade 2 Titanium Tubing Titanium tubing and pipe are increasingly used in a variety of applications where stainless steel and other materials are inefficient in many cases. A common titanium mill product is titanium tubing, which is used in a variety of products due to its excellent corrosion resistance and strength-to-weight ratio. The development of many different alloys has expanded the use of titanium in industries ranging from industrial and chemical processing to power generation. The American Society of Mechanical Engineers has approved most titanium alloy grades, which means more choices are available for a variety of projects. While grades 1, 2, 3, 7, 9, 11, etc. can be used, grade 2 is suitable for most situations.
