What are the differences in oxidation rates between stainless steel grades in outdoor armchairs?
When selecting stainless steel for outdoor armchairs, understanding oxidation rates across different grades is crucial for durability. Common grades like 304 and 316 stainless steel exhibit varying resistance to corrosion due to their alloy compositions. Grade 304, containing 18% chromium and 8% nickel, offers good resistance but may oxidize in coastal or high-humidity environments. Grade 316, with added molybdenum (2-3%), provides superior corrosion resistance, making it ideal for harsh outdoor conditions. Lower-grade steels (e.g., 430) lack sufficient nickel, leading to faster rusting. Factors like salt exposure, pollution, and maintenance also influence oxidation. Choosing the right grade ensures longevity and aesthetic appeal for outdoor furniture.
