What are the detection methods of chromium steel?

1, low-carbon chromium steel can be measured by brinell hardness tester or rockwell hardness tester.

2. Annealed and quenched medium-carbon chromium steel can be measured by Brinell hardness tester or Rockwell hardness tester.

3. The quenched medium-carbon chromium steel can be measured by Rockwell hardness tester.

4. High-carbon chromium steel can be measured by Rockwell Hardness Tester C ..

5. Chromium steel with carburized and nitrided surface should be measured by surface Rockwell hardness tester or Vickers hardness tester.

6. For large workpieces, Shore hardness tester and simple hammer Brinell hardness tester can also be used for measurement.

7. For nondestructive testing, ultrasonic testing and magnetic saturation testing can be used.

8. Special large workpieces can be detected by special mechanical devices. For example, during the test, the ball of the rolling bearing falls on the high-hardness steel plate from a certain height. Because the steel plate is at a certain angle, the high hardness ball jumps far, the low hardness ball jumps close, and the medium hardness ball jumps in the middle. And then collected by respective collecting devices, that is, hardness measurement and sorting are realized.

Chromium is one of the main alloying elements in heat-resistant steel. Chromium steel refers to alloy steel containing chromium, which is hard, wear-resistant, corrosion-resistant and rust-free, and can be used to manufacture machines and tools. It has high oxidation resistance and corrosion resistance. Other elements, such as molybdenum, vanadium, tungsten, titanium, niobium and boron, are often added for different use environments.
