Purpose This specification@ in conjunction with the general requirements for peening media covered in AMS2431@ establishes the requirements for the procurement of cast steel shot with a hardness of 55 to 62 HRC. Application Cast steel shot@ high hardness@ have been used typically 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@ high hardness cast steel shot is used on parts of hardness 50 HRC or over.
