N08367
N08367 is a typical 6-molybdenum (high molybdenum content 6.3%) super austenitic stainless steel. Resistant to chloride pitting, crevice corrosion and stress corrosion The ability is better than 3 series stainless steel and the cost is lower than corrosion-resistant nickel-based alloy. Shows good anti-corrosion properties in various severe corrosive environments It is suitable for high chloride aqueous solutions and chloride corrosive environments. Its comprehensive corrosion resistance has greatly improved compared to 316L. For other corrosion-resistant nickel-based alloys such as C-276, the corrosion resistance is similar, but the cost is more advantageous. Used in various high chloride environments: bleaching Chemicals with high content of whitening agents (sodium hypochlorite, chlorine dioxide), halogens and salt or seawater.
