| Corrosion Resistance |
| Quite very good corrosion resistance with respect to organic and natural substances, oxidating options, foodstuff, sterilizing options. Excellent resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of hot chloride answers and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 shows slightly best corrosion resistance with respect to AISI 304/304L stainless steels. |
