Surface Treatment
What surface treatments are commonly used for DX51D+Z80 coils?
Surface treatments such as passivation, oiling, lacquer sealing, and phosphating are commonly used to improve corrosion resistance.
What is the purpose of passivation?
Passivation can reduce rust (white rust) caused by humid storage and transportation conditions.
What is the purpose of oiling?
Oiling can reduce rust on steel sheets during humid storage and transportation conditions. Applying oil to passivated steel sheets and strip further reduces rust in humid storage conditions.
