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