Why are stainless steel outdoor chairs less likely to discolor over time?

Stainless steel outdoor chairs are less likely to discolor over time due to their unique material properties. Unlike other metals, stainless steel contains chromium, which forms a passive oxide layer on the surface when exposed to oxygen. This layer acts as a protective barrier against rust, corrosion, and UV damage, preventing discoloration. Additionally, stainless steel is highly resistant to moisture, temperature fluctuations, and environmental pollutants, making it ideal for outdoor use. Its non-porous surface also resists staining from dirt or spills. With minimal maintenance, stainless steel chairs retain their sleek appearance for years, offering both durability and aesthetic appeal for outdoor spaces.
