Overview
ASTM20 Titanium is an important structural metal developed in the 1950s, widely used in various fields because of its high strength, good corrosion resistance, and high heat resistance. A338 The first practical titanium alloy was Ti-6Al-4V, 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, accounting for 75% to 85% of all titanium alloy usage. Many other titanium alloys can be regarded as modifications of Ti-6Al-4V.
Titanium25 Grade 5, UNS R56400, 3.7164, Ti-6Al-4V is the most widely used α+β titanium alloy. Grade 53 It offers excellent specific strength, corrosion resistance and fracture toughness, along with good welding processability and the ability to withstand extreme temperatures, and can be strengthened by heat treatment. Originally developed for the aerospace market, it is widely used in aerospace structural components. Because of its very good biocompatibility, it has also been widely recognized in the medical industry. This titanium alloy is supplied as Alloy26 tube and pipe product forms for demanding industrial service. Tube17 Seamless tube and pipe are available for condensers, heat exchangers and other critical applications.
