Chlorides, stress-corrosion cracking concentrated, environment-alloy

Zirconium and its alloys are susceptible to stress corrosion cracking (SCC) in such environments as Fe - or Cu -containing chloride solution, CH3OH -H hahdes, concentrated HNO3, halogen vapors, and liquid mercury or cesium [4,5]. Common test methods, e.g., U-bend, C-ring, split ring, direct tension, double cantilever, and slow strain rate tension, have been used to determine zirconium s susceptibility to SCC. 

The corrosion resistant properties of alloy A1-6XN show exceptional resistance to pitting, crevice attack, and stress cracking in high chloride concentrations and general resistance in various acid, alkaline, and salt solutions found in chemical processing and other industrial environments.
