Stainless Steel Shot

Our particular specialty is in stainless steel cut-wire shot. Stainless steel cut-wire shot is being used in an increasing number of important applications where ferrous contamination in blasting stainless steel, titanium, aluminum, or other non ferrous work objects could be harmful. It is also used in peening these metals (stainless steel, titanium, brass or aluminum) in work objects that are subject to stress corrosion cracking. Shot produced from type 302/304 stainless steel has a hardness in the 50– 60 Rockwell C range. This has proven to be an ideal hardness for most shot peening applications. Our shot is certified to meet MILS 13165C, SAE J441, AMS 2431/3 and AMS 2431/4. Our shot is available in conditioned form (spherical) with certification to existing aircraft specifications for roundness, particle size, and weight. Conditioned cut-wire shot has a Rockwell C hardness of 50 to 60 HRC depending on size

Stainless shot is also available in a 316 grade. This is a higher nickel-bearing grade and offers superior corrosion resistance in heat exchangers and fluidized beds. Being non magnetic, it can be used in tumbling or vibratory applications where magnetic separation is desired. This material has a Rockwell C hardness of 30 – 35. Type 430 is available where lower hardness media is desired. This is a straight chrome grade and has a Rockwell C hardness of approximately 35.

Pellets has recently added a 200 series stainless steel alloy to its cut wire product line.  Our 200 series cut wire shot has the same hardness range of 50 to 60 Rockwell C as our 302/304 cut wire shot.  However, the 200 series product offers significant cost savings due to approximately 70% less nickel content compared to 302/304 stainless.
