How does cast iron’s susceptibility to rust compare to wrought iron in rainy climates?
Cast iron and wrought iron differ significantly in their resistance to rust, especially in rainy climates. Cast iron, due to its higher carbon content, is more prone to rusting when exposed to moisture. Without proper coatings or maintenance, it can develop rust quickly in damp conditions. Wrought iron, on the other hand, contains less carbon and more slag fibers, which provide better corrosion resistance. While both metals can rust over time, wrought iron generally holds up better in wet environments. Regular sealing and protective treatments can help extend the lifespan of both metals, but wrought iron remains the more durable choice for rainy climates.
