Steel Shot

Steel Shot is produced from high carbon steel that is melted and subsequently atomized by pouring streams of molten steel through high pressure water jets The shots are then homogonised by reheating and then refined by quenching. The shots are then dried and reheated in a tempering furnace. Finally the shots are screened into the appropriate grades. Steel Shot is manufactured to a very high standard to ensure uniform hardness, density and microstructure.

 

Description

Steel Shot is used for descaling steel components, typically using a centrifugal wheel airless blasting machine and in the foundry industry to remove sand from components.

Chemical Composition:

Carbon 0.85-1.20%
Silicon 0.45-1.50%
Manganese 0.35-1.20%
Phosphorus <0.05%
Sulfur <0.05%

Standard Hardness:
The hardness of 90% of all shot paticles shall be within the range of 40-50 HRc. (Rockwell C)

General Appearance:
The steel shot shall be as nearly spherical as commercially possible and no more 20% of the shot particles shall have objectionable defects.

Microstructure:
The microstructure of steel shot shall be uniform martensite, tempered to a degree consistent with the hardness range,with fine,well distributed carbides, if any.

Density:
The density of steel shot shall be not less than 7.4 g/cc.
