Titanium plates have high corrosion resistance and specific strength, and are widely used in electric power, chemical industry, aviation components, building materials, sports equipment, medical treatment and other fields and are still expanding. From the point of view of use and manufacturing technology, titanium plates are low in price, high in performance, multi-functional, and easy to produce. From the viewpoint of expanding usage, grade 5 titanium round bar represented by Ti-1Fe-0.35O, Ti-5Al-1Fe, Ti-5Al-2Fe-3Mo (mass%) make full use of cheap elements such as Fe, O, N, etc. It is a pure titanium plate for various surface finishing and to improve the resistance to discoloration. A remarkable feature of titanium plate is its strong corrosion resistance. This is due to its particularly high affinity for oxygen, which can form a dense oxide film on its surface, which can protect titanium from medium corrosion. , Neutral saline solution has good stability in oxidizing medium, and has better corrosion resistance than existing stainless steel and other commonly used non-ferrous metals.
The quality of the AMS 4900 CP Titanium Plate is largely determined by the smelting process of the titanium plate manufacturer, including the chemical composition of titanium, the cleanliness of titanium water (gas, harmful elements, inclusions) and the quality of the slab (component segregation, decarburization and Its surface condition), these aspects are the key control points of the smelting operation. In addition, industrial titanium plates also require sufficient hardenability to ensure uniform microstructure and mechanical properties throughout the spring section. The main cause of fatigue cracks is the inclusion of oxides in titanium, and Class D inclusions are more harmful to fatigue life than Class B inclusions. Therefore, foreign titanium factories and automobile factories have put forward higher requirements for oxide inclusions in industrial titanium plates. For example, the Swedish SKF standard requires that the oxygen content in titanium is less than 15×10-6, and class D inclusions are lower than class B inclusions. Thing. In particular, the inclusions of Al2O3 and TiN are extremely harmful to the fatigue life of titanium springs. In order to produce high-quality industrial Grade 23 Titanium Sheet, special smelting methods such as electric furnace-electroslag remelting or vacuum arc remelting are usually used in the past.
Because grade 7 titanium alloy plate and titanium rods have special physical and chemical properties, the welding process is very different from other metals. Titanium welding is a TiG welding process that effectively protects the welding area with inert argon gas. Before use, check the factory certificate on the bottle body to verify the purity index of the argon gas, and then check the bottle valve for leaks Or failure. The metal in the welding zone is not contaminated by the reactive gas N0H and the harmful impurity element CFeMn above 250℃. The purity should not be lower than 99.98%, the water content should be lower than 50Mg/m32 Argon: industrial grade pure argon. Coarse grain structure cannot be formed. The welding process must be in accordance with the predetermined construction sequence, and no large welding residual stress and residual deformation can be generated. and so. Strictly follow the process quality management standards and implement quality control of the entire process. All factors of man, machine, material and method are in a well-controlled state, so as to ensure the welding quality of titanium tubes within a reasonable construction period.
