| Corrosion Resistance |
| Really very good corrosion resistance with regard to natural substances, oxidating solutions, foodstuff, sterilizing solutions. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride options and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 exhibits slightly best corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
