1. The hollow ratio of non-standard steel shot is high. The hollow ratio of the national standard steel shot is relatively much lower.
2. The carbon content of the national standard steel shot is 0.85-1.20%, and the carbon content of the non-standard steel shot is much higher than that of the national standard steel shot, and it is fragile during the hitting process.
3. The content of manganese in the national standard steel shot is 0.60-1.20%, and the content of manganese in the non-standard steel shot is low, the toughness of the steel shot is poor, and the amount of dust in the hitting process is large.
4. The heat treatment temperature of non-standard steel shot is high, and the hardness is reduced, thus affecting the hitting efficiency.
