As a precision measuring tool, internal thread addendum gages play a vital role in the manufacturing industry. The choice of its material is not only directly related to the accuracy of measurement, but also affects the service life and applicable environment of the tool. Therefore, in the selection of the material of internal thread addendum gages, it is necessary to comprehensively consider the balance between durability and precision.First of all, from the perspective of durability, internal thread addendum gages need to withstand frequent measurement operations and possible external factors such as collisions and friction. Therefore, it is crucial to choose a material with high hardness and wear resistance. Common durable materials include high-speed steel, cemented carbide, and stainless steel. High-speed steel is suitable for general measurement environments with its good hardness and wear resistance; cemented carbide has higher hardness and wear resistance, and is particularly suitable for high-precision and high-load measurement tasks; and stainless steel performs well in humid or corrosive environments due to its excellent corrosion resistance.However, durability is not the only consideration. Precision is also an indispensable quality of internal thread addendum gages. In order to ensure the accuracy of measurement, the material of the gauge needs to have stable size and shape, as well as a low thermal expansion coefficient. In this regard, materials such as cemented carbide and bearing steel are the first choice for high-precision measurement due to their high stability and low thermal expansion.In practical applications, the material selection of internal thread addendum gages also needs to consider the specific use environment and needs. For example, in situations where large mechanical stress needs to be withstood, cemented carbide has more advantages due to its high strength and wear resistance; while in situations where corrosion resistance is required, stainless steel becomes an ideal choice.In addition, with the continuous development of the manufacturing industry, higher requirements are also placed on the material of internal thread addendum gages. The emergence of new composite materials provides more possibilities for the material selection of gauges. These materials not only have excellent durability and precision, but may also have lighter weight, better fatigue resistance and other characteristics.In summary, the material selection of internal thread addendum gages needs to find the best balance between durability and precision. By comprehensively considering the use environment, measurement requirements and material characteristics, the most suitable gauge material can be selected to ensure measurement accuracy and tool life.
