Titanium Grades

Titanium grades are alloyed with different additional elements, granting it the better properties that are required firsthand in various industries.

titaniumMost of the titanium grades are being added with various elements (including vanadium, aluminum, molybdenum, nickel, chromium, and zirconium) to improve its combined mechanical properties like conductivity, heat resistance, creep, microstructure, corrosion resistance, and ductility.

This process of fusing other elements to titanium is a significant part for the improvement of its resistance to slightly reducing and corrosive environments.

Commercial pure titanium grades vary to their qualities, enabling them to be used vastly in different fitted applications. Some titanium grades possess great formability, best explains why some titanium are mostly available in plates and tubing.

Below are some of the vast applications of titanium grades:

  • Chlorate manufacturing
  • Desalination
  • Dimensional stable anodes
  • Chemical processing
  • Automotive parts
  • Airframe structure
  • Marine industry
  • Mechanical industry
  • Architecture

Other titanium grades also posses great ductility and formability as well as weldability which make them suitable for heavy duty applications like hydrocarbon manufacturing, power generation, exhaust pipe shrouds, CPI equipment, cryogenic vessels, airframe components, surgical hardware, heat exchangers, pickling baskets, and heat exchangers.
