The key to grinding high carbon steel metallographic samples is to select the right metallographic sandpaper.


The market is full of metallographic sandpaper, with different brands, origins, specifications and models, and grinding media There are too many, how to choose?


Can you bring all these sandpaper and try them out one by one before comparing and evaluating them? The workload is large, the time is long, and it may not be possible to achieve it without three years or two years of effort. Therefore, this move is not practical, so what should we do? Key points: High carbon steel metallographic sample grinding metallographic sandpaper should be selected in this way, let's take a look together!

When you see this, congratulations, here comes the solution! The silicon carbide metallographic sandpaper produced by QMAXIS in the United States is simply; Produced by grinding high carbon steel samples;! The experimental data tells you that using QMAXIS silicon carbide metallographic sandpaper to grind high carbon steel metallographic samples takes an average of 2 minutes! And the grinding quality of the sample surface drops!

Using QMAXIS metallographic sandpaper, under normal circumstances, each process can be completed in an average of 2 minutes, and rework is rare. Compared to the average 3-4 minute grinding time of ordinary sandpaper, the time has been reduced by nearly half. More importantly, the surface of the high carbon steel sample ground with QMAXIS sandpaper is flat and smooth, effectively removing scratches and deformation layers, laying a good foundation for the next grinding and polishing process. To prepare high carbon steel samples quickly and well, use QMAXIS metallographic sandpaper.

To help more high carbon steel users understand the preparation method using QMAXIS metallographic sandpaper, pulse detection application engineers recommend using the three-step grinding method, starting from P180 sandpaper, the second step using P800, and the third step using P2500. The grinding plan is shown in the table below:
