Advantages

• Corrosion Resistance: Superior to carbon steel in harsh environments without additional coatings.
• Hygienic Properties: Smooth surfaces of 304/316 make them ideal for sanitary applications (FDA-compliant).
• Heat Resistance: Maintain strength at elevated temperatures (e.g., 316 up to ~815°C).
• Recyclability: High scrap value and fully recyclable, reducing environmental impact.
