Salt spray test - corrosion resistance of electrogalvanizing products

2022-06-16

Corrosion is a key issue in extreme marine, mining, industrial and mobile applications, as well as many other markets, which can cause direct and indirect economic loss. In this regard, higher requirements are needed for the corrosion resistance of hydraulic joint fittings.

After more than 20 years of continuous exploration, trial, and development, the continuous iteration of mechanical production equipment update, DME greatly improved the standard corrosion resistance of hydraulic fittings. According to SAE standardized salt spray test, there will be no white rust in harsh environment for 168 hours and no red rust for 500 hours. Excellent.corrosion resistance can provide a safe and effective linkage solution for your hydraulic system.
