Shot blasting rust removal cleaning steel shot S330 alloy steel shot

Description :

　　1. Non national standard steel shot refers to a general term for steel shot whose various indicators do not meet the national standard level.

　　2. National standard alloy steel shot refers to steel shot that has been quenched once, with a hardness of HRC40~50. Among them, carbon C: 0.85% -1.20%, silicon Si：0.40%-1.20%、Mn：0.60%-1.20%（S170：0.50%-1.20% S110，S70：0.35%-1.20%） Sulfur S ≤ 0.05%, phosphorus P ≤ 0.05. This type of steel shot has a wide range of applications and is widely used in various industries for cleaning, strengthening, and balancing.

　　3. LD precision machining steel shot is actually a high-performance national standard steel shot, with the same technical specifications as the national standard steel shot. This type of steel shot undergoes secondary quenching treatment to make the metallographic structure denser, bridge surface microcracks, refine grains, and has a service life 1.3 times that of ordinary national standard steel shot.

　　4. Low carbon steel shot (some customers call it low shell steel shot), this type of alloy steel shot has a hardness of HRC42-48/48-54. Among them, carbon C: 0.10% -0.20%, silicon Si: 0.10% -0.30%, manganese Mn: 0.35% -1.5%, sulfur S ≤ 0.05%, phosphorus P ≤ 0.05%, and alloy elements such as Cr, Mo, Ni, B, Al, Cu are added. The service life is about 1.3 times that of ordinary national standard alloy steel shot.
