Description / Abstract:
Purpose
This specification, in conjunction with the general requirements for peening media covered in AMS2431, establishes the requirements for the procurement of conditioned cast steel shot with a hardness of 45 to 52 HRC.
Application
Cast steel shot, regular hardness, have been used typically for use in peening metal surfaces to impart compressive stresses to these surfaces thereby increasing resistance to fatigue and stress-corrosion cracking, but usage is not limited to such applications. Generally, regular hardness cast steel shot is used on parts of hardness under 50 HRC.
