Corrosion Resistance

Really great corrosion resistance with respect to natural and organic substances, oxidating options, foodstuff, sterilizing options. Very good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride remedies and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 exhibits marginally ideal corrosion resistance with regard to AISI 304/304L stainless steels.

Notes
