These valves feature a well-balanced microstructure of austenite and ferrite, which gives them outstanding mechanical strength and corrosion resistance. The alloy is typically rich in chromium, molybdenum, nickel, and nitrogen, providing excellent defense against pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these valves show impressive tensile and yield strength, good impact toughness, and remarkable fatigue resistance. This means they can operate reliably under pressure changes, cyclic loading, and corrosive environments, making them ideal for critical industrial applications.
