How to choose a suitable hardness tester for carbon steel round bars
When testing the hardness of carbon steel round bars with lower hardness, we should choose a hardness tester reasonably to ensure that the test results are accurate and effective. We can consider using the HRB scale of the Rockwell hardness tester. The HRB scale of the Rockwell hardness tester u...Read more -
Connector terminal inspection, terminal crimping shape sample preparation, metallographic microscope inspection
The standard requires whether the crimping shape of the connector terminal is qualified. The porosity of the terminal crimping wire refers to the ratio of the uncontacted area of the connecting part in the crimping terminal to the total area, which is an important parameter affecting the safet...Read more -
