Factors That Can Cause Stainless Steel To Corrode:transplanting of Plain Iron or Steel onto Stainless Steels
In some applications, particulate residue from a plain steel or iron workpiece may be transferred onto the surface of a stainless steel part or basket. These plain iron or steel particles can disrupt the protective oxide layer of a stainless steel workpiece—ruining its corrosion resistance so that it starts to rust.
The difference between this and the bimetallic corrosion problem listed above is that in this case, the contact between the dissimilar metals is purely accidental and typically without the manufacturer’s knowledge.
A common reason why plain steel or iron residue gets transplanted onto a stainless steel part or workpiece is that equipment used to process one type of material may be used for the other without being properly cleaned between batches.
For example, say a wire bending robot was used to bend plain iron wires for several hours, then immediately used to bend stainless steel wires. Some iron particles would likely be left behind on the bending robot’s manipulators, which could then be transferred to the stainless steel wires being bent.
To prevent the transplanting of plain steel or iron (or any other metals) to stainless steel workpieces, it’s important to thoroughly clean and prepare equipment when changing over to new material. Some equipment, such as steel brushes, should never be shared between different metal types.
