Duplex Steel Bars are crafted from a well-balanced blend of austenite and ferrite, typically featuring 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen to boost strength. This unique composition offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these bars showcase high tensile and yield strength, outstanding fatigue resistance, and solid toughness. Duplex Steel Bars maintain their mechanical integrity even in high-stress and corrosive environments, boasting nearly double the yield strength of standard austenitic stainless steels, along with good ductility, thermal stability, and weldability for a variety of industrial applications.
