How is the chloride corrosion resistance of advanced stainless steel reflected in practical use?

Chloride ions in seawater, brine and desulfurization waste liquid easily break down the passive film of standard stainless steel, triggering local pitting leakage. Advanced stainless steel with high molybdenum and nitrogen content greatly raises its critical pitting temperature, slowing down film damage under long-term chloride immersion. Super duplex grades can run continuously in full seawater without anti-corrosion coating, while super austenitic types endure hot concentrated chloride solutions in chemical workshops. This unique trait cuts frequent maintenance and replacement costs of industrial pressure equipment.
