(1) Due to the small elastic modulus of titanium alloy, the clamping deformation and stress deformation of workpiece during processing are large, which will reduce the machining accuracy of workpiece; The clamping force should not be too large when installing the workpiece, and auxiliary support can be added if necessary.

(2) If cutting oil containing hydrogen is used, hydrogen will be decomposed and released at high temperature during cutting, which will be absorbed by titanium and cause hydrogen embrittlement; It may also cause high-temperature stress corrosion cracking of titanium alloys.

(3) The chloride in the cutting oil may also decompose or volatilize toxic gas during use, so protective measures should be taken during use. After cutting, the parts should be cleaned with chlorine free detergent in time to remove chlorine residues.

(4) It is prohibited to use tools and fixtures made of lead or zinc based alloys to contact titanium alloys, and copper, tin, cadmium and their alloys are also prohibited to use.

(5) All tools, fixtures or other devices in contact with titanium alloy must be clean; The cleaned titanium alloy parts shall be protected from grease or fingerprint pollution, or salt (sodium chloride) stress corrosion may be caused later.  

Titanium has excellent corrosion resistance, mechanical properties and technological properties, and is widely used in many sectors of the national economy. This is of great significance to increase output, improve product quality, extend equipment use, reduce consumption, reduce internal consumption, reduce costs, prevent pollution, improve working conditions and improve labor productivity.

Titanium has become one of the main anti-corrosion materials in chemical equipment, and has established its anti-corrosion status in chemical equipment. As an ideal material for chemical equipment, titanium and titanium alloys have been widely used in chemical production due to their excellent corrosion resistant structural materials.

The application scope of titanium materials in the chemical and metallurgical fields includes the manufacturing of various equipment, heat exchangers, electrolytic plates, reactors, coolers, separators, concentrators, absorption towers, and various continuously matched pipes, valves, accessories, gaskets, pumps, etc.
