These bars are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, creating a well-balanced duplex microstructure of ferrite and austenite. This unique composition offers impressive tensile and yield strength, along with excellent resistance to stress corrosion cracking, pitting, and crevice corrosion, while also enhancing weldability. They maintain remarkable toughness and dimensional stability, even under high-pressure and elevated-temperature conditions, making them perfect for critical industrial applications.
