Steel shot, due to its special superior performance, is widely used in many fields such as castings, forgings, surface treatment of machined parts and surface treatment of parts after heat treatment. Today, I will introduce the selection criteria of shot blasting.
1. Conditions that shot blasting materials should have
1) Fast cleaning speed
2) Stable quality
3) Low consumption
2. Relationship between density and life
1) Hardness is proportional to cleaning speed, but inversely proportional to life. Therefore, high hardness means fast cleaning speed.
2) Moderate hardness and excellent rebound properties can fully clean every corner during blasting, reducing processing time.
3) Internal defects of shot blasting materials such as pores, cracks, internal shrinkage holes, etc. can affect its life and increase consumption.
4) If the density is greater than 7.4g/cc, the internal defects should be minimized.
3. Selection criteria of shot blasting materials
1) Appropriate hardness
2) Sufficient density
3) Appropriate metallographic structure
