Cut
wire shots are manufactured by cutting wire into lengths equal to wire
diameter (also called Wire pellets). If required, the particles can be
conditioned (rounded) to remove the sharp corners that are produced during
the cutting process. We have adopted strict quality control procedures in
order to manufacture steel cut wire shots that comply with industry standards and
norms. Cut particles are an effective abrasive due to the sharp edges that are created during the cutting process. However, a normal cut shot is not a desirable shot peening media and the sharp edges, which are potentially damaging to fatigue life, must be removed in the conditioning process.
Conditioned steel cut wire shots are generally designed in various degrees of conditioning - normal conditioning that meets the shape requirements of SAE J441 specifications, and the less and more rounded special conditioning that fulfills the requirements of Aerospace specifications, like AMS 2431
Characteristics :
- Good abrasion - improves work efficiency.
- Highly durable - reduces manufacturing time and cost.
- Stable peening effect because of uniform hardness and particle size.
- Low breakage and less dust contribute to a better environment (ISO14001).
- Variety of products available to match the material, hardness and purpose of the work piece.
Hardness Range :
Different hardness ranges are available with cut wire media, which depends on the type of application. Normally, the higher the media hardness, the lower will be the durability. However for shot peening applications, the used shot should be at least as hard as Almen strips or the part being peened, whichever is harder.
The common hardness ranges in carbon steel cut wire shot, include - blasting applications - HRC 45-50; shot peening high strength parts, like carburized gears and springs HRC 55-60; and Shot Peening softer parts, such as HRC 50-55.
Versatility :
Versatility is one of the most important aspects of steel cut wire shots. High in versatility, these can be made from various materials, such as stainless steel, carbon steel of various hardness levels, aluminium and zinc. Size of media can vary and is not limited to the standards.
Conditioning is done in Standard degrees, including - As-cut, normal, double and special. Some other degrees of conditioning can also be done. Various other hardness ranges can also be provided other than those discussed above.
