The Diagram of Electrochemical Equilibrium of 12X18H10T Steel

Equilibrium potential–pH diagrams for the austenite of a 12X18H10T steel and possible second phases, such as titanium carbides TiC, Cr₂₃C₆-based M₂₃C₆ carbides, FeCr intermetallic compound (-phase) as well as silica and sulfide inclusions are considered. Concurrent effect of titanium, chromium, manganese, and silicon, on the chemical and electrochemical stability of stainless steel is discussed.
