Why isn’t titanium widely used in the chemical instrumentation industry?

There are quite a few titanium products available, but their price is much higher than that of stainless steel; I definitely wouldn’t choose them unless it’s necessary.

There are several reasons why titanium is not as widely used in the chemical instrumentation industry as tantalum, zirconium, and Hastelloy. First of all, price is an important factor. Compared to tantalum, zirconium, and Hastelloy, titanium is more expensive, making it less competitive in the market. Secondly, the difficulty of processing titanium is also a limiting factor. Titanium materials have relatively poor machinability; issues such as tool wear and difficulties in welding arise, posing challenges to the machining process. This increases production costs and may lead to quality issues. Furthermore, although titanium possesses excellent corrosion resistance, its performance in this regard is slightly inferior to that of tantalum, zirconium, and Hastelloy. Under certain special chemical environmental conditions, titanium may not provide sufficient corrosion resistance; therefore, in some chemical processes, materials such as tantalum, zirconium, and Hastelloy are preferred. In summary, factors such as price, processing difficulty, and corrosion resistance collectively influence the extent of titanium’s use in the chemical instrumentation industry. However, with technological advancements in titanium materials and changes in market demand, the use of titanium in this industry is likely to increase in the future. .

It can only be said that the original poster does not have a comprehensive understanding of the use of titanium in the chemical industry. In the chlor-alkali industry, particularly in the process of brine purification, titanium materials are widely used. Although they are more expensive, they can be considered a solution that provides long-term benefits. Titanium is also commonly used in other chemical processes that involve reactive halogens. In some offshore oil projects, many titanium-based instruments and equipment components are also used.
