Tips: File hardness test
The characteristics of file hardness testing are easy to operate, easy to carry, not limited by the size and shape of the workpiece, can be tested quickly, and has good reliability. Therefore, in production practice, files are often used to detect some workpieces whose appearance is not suitable for testing with a hardness tester, and those with decarburized surfaces.
File inspection hardness is suitable for the quality inspection of various steels after heat treatment. The commonly used steels include structural steel, alloy structural steel, carbon and alloy tool steel, high-speed steel, die steel and carburizing steel. The heat treatment process includes ordinary quenching, high Frequency quenching, vacuum quenching, carburizing, carbonitriding, nitriding, etc. In addition, it is also suitable for the quality inspection of steel parts, especially in the mass production process, a certain percentage of products are often sampled, and the hardness is tested with a hardness tester, and the remaining products are 100% inspected with a file.
