310S Stainless Steel Coil is a high‑alloy austenitic heat‑resistant steel with 25% Cr + 20% Ni content. It offers excellent oxidation resistance up to 1,150°C, superior thermal cycling stability, and outstanding corrosion resistance in harsh environments. Widely used in furnaces, heat exchangers, petrochemicals, and high‑temperature equipment in Indonesia.
Key Features：
✅ Extreme Heat Resistance: Continuous service at 1,050–1,150°C, short‑term up to 1,250°C
✅ Superior Oxidation Resistance: 3× better than 309S; stable Cr₂O₃ oxide layer
✅ High Corrosion Resistance: Resists sulfidation, carburization, and intergranular corrosion
✅ Excellent Weldability: Low carbon (≤0.08%) minimizes carbide precipitation
✅ Good Formability: Easy to roll, bend, and fabricate
✅ Non‑Magnetic: In annealed condition, suitable for precision equipment
