These fittings are primarily made up of chromium, nickel, molybdenum, and nitrogen, which create a balanced microstructure of austenite and ferrite. This unique composition boosts their resistance to localized corrosion and enhances their mechanical strength. They showcase impressive tensile and yield strength, outstanding impact toughness, and remarkable resistance to chloride-induced stress corrosion cracking. Thanks to this combination of features, they ensure long-lasting performance and structural integrity, even in harsh environments with high pressure and temperature.
