Why can't stainless steel be polished with steel grit

　　If you want to do a good job in basic polishing of stainless steel materials, you definitely need to use some suitable abrasives. Steel grit is indeed frequently used, and many metal processing generally use this type of abrasive. Its price is favorable, the hardness is also relatively good, and it can also create some frosted processing modes. But generally stainless steel does not use such abrasives, why is that?

　　The hardness is relatively high

　　Because the hardness of many steel sandstones is not very high, and the hardness of stainless steel itself is very high, it will still be very difficult to directly impact with steel balls or other materials, which naturally cannot achieve good processing results. So if we really want to achieve good processing results for stainless steel, we should definitely choose some abrasives with higher hardness, so that at least the subsequent processing results will be better.

　　Easy to rust

　　Since we want to process stainless steel well, we still need to consider whether we can choose some cost-effective abrasives. It is recommended that everyone should still pay attention to the surface condition of stainless steel processing. If there is really a rush to mine due to steel sand damage, some iron filings will also adhere to the surface of the stainless steel workpiece, which can easily cause rusting and make the surface look unsightly. Therefore, this mode of processing is generally not chosen.

　　In fact, everyone should know that iron filings are very easy to generate iron oxide, and the composition of iron oxide is relatively more stable. If there is such rust on the surface of stainless steel for a long time, corrosion points will form later, and it is unlikely to be removed.
