Flanges can be made of either steel or stainless steel, depending on the application. Steel flanges typically refer to carbon steel flanges, which offer high strength and durability, suitable for general industrial environments. Stainless steel flanges, due to their corrosion resistance, are commonly used in chemical, food, and other fields with high hygiene requirements. Environmental factors and cost must be considered when choosing.
Composition Differences: Stainless steel contains alloying elements such as chromium, forming an antioxidant layer; carbon steel is primarily composed of iron and carbon.
Corrosion Resistance: Stainless steel performs better in humid or chemical environments.
Cost Comparison: Stainless steel is generally more expensive, but has lower maintenance costs.
