ASTM B338 / ASME SB338 Grade 5 / UNS R56400 Titanium Alloy Seamless Tubes

ASTM B338 / ASME SB338 Grade 5 / UNS R56400 Titanium Alloy Seamless Tubes and Pipes

What is Grade 5 Titanium Tube?

A titanium grade 5 seamless tube could be manufactured from hollow billet by any cold reducing process or cold drawing process. This process is one that will yield a seamless Titanium Gr 5 High Pressure Tube, thereby meeting the requirements prescribed. Alternatively, the Titanium Grade 5 Welded Tube is to be made from a flat rolled product by using an automatic arc welding process on the alloy.

Grade5, UNS R56400, 3.7164, Ti-6Al-4V is the most widely used α+β titanium alloy. It has excellent specific strength, excellent corrosion resistance and fracture toughness, as well as good welding processability and the ability to withstand extreme temperatures, and can be strengthened by heat treatment. The alloy was originally developed for the aerospace market and is widely used in aerospace structural components. Because of its very good biocompatibility, it has also been widely recognized in the medical industry.

ASTM B338 Tensile Strength of Titanium Tubes

Titanium is an important structural metal developed in the 1950s, which widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. The first practical titanium alloy is Ti-6Al-4V alloy which successfully developed in 1954. Due to its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility. It has become the flagship alloy in the titanium alloy industry, and the amount of this alloy used has accounted for 75% to 85% of all titanium alloys. Many other titanium alloys can be regarded as modifications of Ti-6Al-4V alloy.

Applications
