In the past, the hardness testing of tin boxes mostly used a desktop integrated surface Rockwell hardness tester, which used a general steel flat anvil to test the HR30T hardness.

  For many years, due to the adoption of the internationally recognized HR30Tm hardness indication method in the national industry standard GB/T2520-2000 for tinplate, China has begun to use diamond anvil to test the HR30Tm hardness value of tinplate.

However, to test the hardness of HR30Tm, a diamond anvil is required, and there are very few Rockwell hardness testers in China that can purchase such spare parts. Because suitable diamond anvil cannot be purchased, and the surface hardness tester for desktop all-in-one machines is relatively expensive. Therefore, the application of HR30Tm hardness indication method in China's tinplate manufacturing industry is not widespread. Especially at the level of manufacturers of tin boxes, although it is widely recognized that the hardness of tinplate is important, it is related to the quality of the produced and processed goods, productivity, and economic benefits of the company. However, most companies have not conducted hardness checks on the purchased tin boxes and materials.
