Relationship between hardness and service life of cast steel shots

　The higher the hardness of the cast steel shots, the faster the liquidation speed, but the shorter the service life, the larger the consumption. All the hardness is about HRC40-50, and the best application effect. The cast steel shots with moderate hardness and excellent anti elasticity can reach every center of the clearing room and reduce the disposal time.

　　1. The hardness is directly proportional to the cleaning speed. The higher the hardness is, the faster the cleaning speed is, the greater the consumption is, and the shorter the service life is. The manufacturing process determines the size of the cast steel shots. The larger the diameter is, the higher the surface roughness after cleaning is. However, the working efficiency is also very high, which is also larger than the wear.

　　2. Enough density to have stable quality, which can reduce fracture and wear during cleaning.

　　3. Internal defects such as porosity cracking and internal shrinkage can affect the life of the material and increase the consumption. The hardness is directly proportional to the cleaning speed, but inversely proportional to the service life. Therefore, the hardness is high, the cleaning speed is fast, but the life is Cast Steel Shots S280 and the consumption is large, so the hardness should be moderate to produce the most economic effect.
