Are ASTM A 453 GR 660 Class A Nuts Susceptible to galvanic corrosion?

ASTM A453 Grade 660 Class A nuts typically resist galvanic corrosion due to their alloy composition, which includes corrosion-resistant elements like nickel and chromium. These elements form protective oxide layers that mitigate galvanic reactions when in contact with dissimilar metals. However, in environments prone to galvanic corrosion, such as marine settings, it’s advisable to apply proper material pairing and surface treatments to further enhance their resistance and ensure long-term durability. Regular maintenance and adherence to industry guidelines also contribute to maintaining their resistance to galvanic corrosion over time.
