What are non-standard steel shots? What is the difference between non-standard and national standard steel shot?

　　Non-standard steel shots refer to steel shots that do not meet national standards, and there are clear specifications in the national standards. The content of beneficial metals such as gold in non-standard steel shot is relatively small, and harmful elements such as sulfur and phosphorus also exceed the standard.

　　What are the disadvantages of non-standard steel shot? Compared with national standard steel shot, non-standard steel shot has a higher empty shell rate, is easily broken, and has a relatively large amount of dust.

　　What is the difference between non-standard steel shot and national standard steel shot?

　　Mainly reflected in three aspects: cost performance, lifespan and empty shell rate.

　　First of all, in terms of cost performance, the price of non-standard steel shot is cheaper than the price of national standard steel shot.

　　Secondly, regarding the service life of non-standard steel shots and national standard steel shots.

　　The service life of non-standard steel shots is much lower than that of national standard steel shots.

　　Finally, about the empty shell rate.

　　The empty shell rate of non-standard steel shot is 1.2 times or even higher than that of national standard steel shot. Therefore, in summary, the cost-effectiveness of national standard steel shot is still higher than that of non-standard steel shot.
