OILED | O | This surface treatment can reduce the white rust generated on the
surface of the product during transportation and storage. The anti
rust oil applied is generally not used as rolling oil and stamping
lubricating oil for subsequent processing, and the anti rust effect
is worse than that of passivation method. |

explicitly requests not to undergo surface treatment during the
ordering period, and it must be specified in the contract. In this
case, the surface of steel plates and strips is prone to white rust
