There will inevitably be losses in the use of steel shot and grit, and there will be different losses because of the way of use and the different objects of use. So do you know that the service life of steel shots with different hardness is also different?
Generally, the hardness of the steel shot is proportional to its cleaning speed, that is, the higher the hardness of the steel shot, the faster its cleaning speed, which also means that the consumption of the steel shot will be greater and the service life will be shorter.
Steel shot has three different hardnesses: P (45-51HRC), H (60-68HRC), L (50-55HRC). We take P hardness and H hardness as examples for comparison:
P hardness is generally HRC45 ~ 51, processing some relatively hard metals, can increase the hardness to HRC57 ~ 62. They have good toughness, longer service life than H hardness, and a wide range of applications.
H hardness is HRC60-68, this kind of steel shot hardness is high, refrigeration is very brittle, very easy to break, short life, application is not very wide. Mainly used in places requiring high shot peening intensity.
Therefore, the majority of customers purchase steel shots with P hardness.
According to the test, we find that the number of cycles of steel shot with P hardness is higher than that of H hardness, H hardness is about 2300 times, and P hardness cycle can reach 2600 times. How many cycles did you test?
