Way Of Tinplate Hardness Test
Jan 30, 2019

In the past, the hardness test of tinplate was mostly based on a desktop surface Rockwell hardness tester, and the ordinary steel flat anvil was used to test the hardness of HR30T.

For many years, since the national standard GB/T2520-2000 for tinplate has adopted the internationally accepted HR30Tm hardness representation method, the diamond anvil and the HR30Tm hardness value of the tinplate have been tested in China.

However, testing a HR30Tm hardness requires a diamond anvil, and domestic Rockwell hardness testers rarely have such accessories available. Bench-top surface hardness testers are more expensive because suitable diamond anvils are difficult to obtain. Therefore, the application of the HR30Tm hardness representation method in the domestic tinplate industry is still not widespread. Especially in the use of tinplate manufacturers, although people also know that the hardness of tinplate is very important, it is related to the quality of processed products, related to production efficiency and business benefits. However, most companies have not re-examined the hardness of the purchased tinplate.
