These duplex steel bright bars are made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, featuring a balanced ferritic-austenitic microstructure. This special composition gives them excellent mechanical properties, such as high tensile strength, yield strength, and outstanding toughness. They are particularly resistant to stress corrosion cracking and pitting, making them perfect for tough environments. The microstructure also allows for good weldability and formability while keeping dimensional stability during thermal cycling. Additionally, duplex steel bright bars boast impressive fatigue resistance and impact strength, blending the best characteristics of austenitic and ferritic stainless steels, which makes them highly reliable for demanding industrial applications.
