Titanium Alloys In The Valve Industry Is Widely
Jun 13, 2016

Corrosion resistance of titanium alloy valve is ideal for use in corrosive environments! Valves titanium alloy materials were developed in the 20th century as an important structural metals, titanium valves for high strength, corrosion resistance and good, high heat resistance and is widely used in various fields. In many countries of the world have recognized the importance of titanium alloy materials, have to research and development, and has been applied. Titanium is a 1954 United States developed Ti-6Al-4V alloys, due to its heat resistance, strength, ductility, ductility, formability, weldability, corrosion resistance and biocompatibility are good, ACE alloy of titanium industry, usage has accounted for all of the alloy titanium alloy 75%~85%. Many other modification of titanium alloys can be thought of as Ti-6Al-4V alloy. 20th century 50-60 's, primarily development of aero-engines with high temperature titanium alloys and body structure of titanium alloys, 70 's developed a number of corrosion resistant titanium alloys, 80, further development of corrosion-resistant titanium alloy and high-strength titanium alloy. Heat-resistant titanium alloy using temperature has risen from 400 c 50 up to 90 600~650℃. A2 (Ti3Al) and r (TiAl) alloys appeared, made the use of titanium in the engine parts from the engine heat exchanger (fan and compressor) to the hot end of the engine (Turbo) direction. Structure of titanium alloy high strength and high plasticity, high strength and high toughness and high modulus and high damage tolerance development. In addition, since in the 1970 of the 20th century, there were Ti-Ni, Ti-Ni-Fe, Ti-Ni-Nb, shape memory alloys, and get more and more applications in engineering.
