Steel shot will inevitably suffer loss during use, and it will also have different loss due to different use methods and objects. So do you know what factors determine the service life of steel shot?
First of all, the service life of steel shot has a lot to do with the hardness and density of steel shot.
Usually, the hardness of the steel shot is directly proportional to its cleaning speed, that is to say, 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 short. The size of the steel shot is not completely uniform during the production process. Generally, the larger the diameter of the steel shot, the higher the efficiency when cleaning the rough surface, but at the same time the greater the wear of the steel shot.
Another important factor that determines the service life of the steel shot is the density of the steel shot. Only a steel shot with a high enough density can have stable quality. This is also during the cleaning process, and there will be no cracks and wear due to low density.
The second is the relationship between the hardness of the steel shot and the rebound. The steel shot with high hardness and good resilience has a longer service life.
The main types of steel shot:
Common steel shots include steel shot, cast iron shot, reinforced steel shot, stainless steel shot, etc.
(1) Steel shot
Steel shot has good toughness and is mainly used for processing hard metals. Its hardness is generally HRC40-50, and the hardness can also be increased to HRC57-62 through technology. Compared with cast iron shot, the service life of steel shot is several times longer.
(2) Cast iron pellets
Cast iron shot is very brittle and is relatively easy to break during processing. It is mainly used in places where high shot peening strength is required. Its hardness is HRC58-65, because of its short life, it is not widely used.
(3) Reinforced steel shot
Reinforced steel shot has good toughness, is not easy to break, and has strong impact resistance. It can reach the spray (shot) shot strength in a short time, has a long service life, and has low consumption during use.
(4) Stainless steel shot is commonly used in steel, steel plate, and steel structure pretreatment production lines, and can be used in conjunction with shot blasting machines and sandblasting machines.
