How to Inspect the Hardness of the Steel Cut Wire Shots?

Posted by Suntec Enterprises India on February 27th, 2020

If your company regularly uses stainless steel cut wire shots to do a variety of works like blasting, pinning of the surface and so on, then it is important that you should only buy the best quality steel shots that are available in the market. However, this is easier said than done because every steel cut wire shot manufacturing company in India proclaimed its products to be the best. If you are confused and want to figure out which carbon steel cut wire shot manufacturer in India produces the best quality products then read this article.

How to figure out the quality of stainless-steel cut wire shots?

1). Looking at the chemical composition: Chemical composition is the fundamental indicator that will give you a clear idea about the quality of the steel cut wire shots. The chemical composition will help you understand the microstructure of the steel shot and how it will impact on heat treatment. Different chemical composition can give varying amounts of strength and hardness. Similarly, certain elements used in the stainless-steel cut wire shots can make them brittle leading to their premature rupture.

2).The hardness of the steel shot: When you are examining the steel shot from a potential supplier and find that the steel grit is too soft, then you must realise that the cleaning speed of it will slow which will impact the work efficiency significantly. When the steel shot is peening then it’s softer grit will not produce the required residual stress, which is impossible to increase the impact time for compensating the applied force. On the other hand, if the hardness of the steel shots is too high, then it will create a regular surface leading to an increase in the broken rate. This will lead to higher consumption and more wear and tear to the equipment. In such a scenario there will be an increase in the maintenance cost of the machine. Therefore, it is important that the steel shots should be suitable hardness.

3). Microstructure: You must look at the microstructure of the steel shot to figure out whether it can resist deformation under extreme heat and pressure. If a steel shot gets easily deformed then it can lead to energy loss as well as decrease the fatigue life leading to premature rupture thereby increasing the usage of such shots.

4). Physical defects: On careful examination, the steel shot should have lesser physical defects.

5). Fatigue life: The fatigue life of a steel shot is described as its resistance to breaking down when blasting. Any steel shot which has a long fatigue life would be the most economical for your company.

Conclusion: These are some of the important points that you must keep in mind when you are trying to find the quality of a steel cut wire shot.
