Hardness and density of cast steel shot
19/3/2021
One of the important properties of cast steel shot: density and hardness
(1) The hardness of steel shot 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 service life is short, the consumption is large, so the hardness should be moderate (about HRC40-50 is appropriate) to produce the most economic effect.
(2) With moderate hardness and excellent rebound, every corner can be fully cleaned in the spraying process, reducing the processing time.
(3) Internal defects such as air hole cracking and shrinkage cavity can affect the service life and increase the consumption.
(4) When the density is more than 7.4g/cc, the internal defects tend to be minimum.
