Dear all,

We are a aerospace components manufacturer in china.

Recently we buy 2 tons cast steel shots form US, the shots meet to specification AMS-2431/1.
Opened the bag, we find that there have rust on the shots surface.
Could anybody tell me how to remove these rust, and no effect to shots quality. ?

In the para.3.6 of AMS-2431/1, Contamination shot shall be clean and free of dirt, grit, oil, or grease. means the clean is allowed for contamination shots.

And the rust will effect lower peening intensity and deficient peening coverage, or not ? or other peening quality, such as part colouration ?

Thank you very much.

Kevin
