TA15 Applications And Special Requirements

TA15 titanium alloy has been used in a large number of manufacturing aircraft and engine load-bearing structural components, especially welded load-bearing structural components, the grade are used in the production of high-temperature requirements of non-standard parts, such as non-standard flower nuts, plugs, bushings, ball, pressure plate, hook pin, screw plugs, plugs, pipe fittings, pipe bending joints, and so on. The grade annealed hardness HB (d) of 3.3 ~ 3.6, tensile strength of 900MPa ~ 1130MPa, tensile strength of 570MPa at 500 ° C, and in the 470MPa can be maintained under the 50h constantly, while the material density is small, high specific strength, corrosion and oxidation resistance is excellent. Meet the above properties can be selected.

Parts design, should consider the general principles of titanium alloy parts design, for example: when used in the general climate environment, no additional surface protection. In the marine climate conditions allow contact with stainless steel, nickel-based alloys without protection, when the working temperature is higher than 300 ℃, should be used to protect the coating or limit the working life. Parts in direct contact with aluminum alloy and structural steel must take reasonable and effective protective measures. For titanium alloy parts with relative motion, isolation coatings should be used to prevent micro-abrasion. Avoid assembly of titanium alloy parts with cadmium-plated steel parts as much as possible.
