How To Know The Hardness Of Wear-resistant Steel Plate?

The hardness of wear-resistant steel plate is one of the most important performance indicators to measure wear-resistant steel plate, and it is also the standard for feedback wear-resistant steel plate. Therefore, hardness is not a simple physical quantity, but a comprehensive performance index reflecting the elasticity, plasticity, strength and toughness of wear-resistant steel plates. So, in general, how do you know the hardness of the wear-resistant steel plate?
First of all, it depends on the standard. Because there are many hardness test methods and different principles, the hardness values of wear-resistant steel plates are different under different standards. Conventional expressions include Brinell (HB), Rockwell (HRC), Vickers (HV), Leeb (HL) hardness, etc., among which HB and HRC are more commonly used.
Secondly, you can look at the grade and implementation standard. In general, the grade of a wear-resistant steel plate can roughly see its hardness range. For example, the Japanese JFE-eh400 wear-resistant steel plate has a surface Brinell hardness of 400±30 (guaranteed value). Implement JIS (Japanese Industrial Standard) G3193.
Finally, instruments with different probes can also be used for measurement. For example, the probe of the Brinell hardness tester is a steel ball, while the probe of the Rockwell hardness tester is diamond.
In addition, the hardness index of wear-resistant steel plate is very important, but when choosing wear-resistant steel plate, the higher the hardness, the better! It also needs to be considered comprehensively according to the use environment, the overall operation of the machine, and work efficiency!
