Duplex Steel Flat Bars are crafted from a well-balanced blend of austenitic and ferritic stainless steels, usually containing 22–25% chromium, 4–7% nickel, 3% molybdenum, and nitrogen to boost strength. These bars showcase impressive tensile strength (620–880 MPa), excellent yield strength (450–550 MPa), and outstanding corrosion resistance, particularly against stress corrosion cracking and pitting caused by chlorides. Their unique dual-phase microstructure enhances fatigue resistance and weldability, making them perfect for tough environments while ensuring structural integrity under pressure and fluctuating temperatures.

To maintain Duplex Steel Flat Bars, regularly clean them to remove debris, inspect for corrosion, and apply protective coatings if necessary. Ensure proper storage to prevent exposure to harsh chemicals or extreme conditions.
Yes, Duplex Steel Flat Bars are suitable for natural gas applications due to their excellent corrosion resistance and strength, making them ideal for pipelines and equipment exposed to natural gas environments.
Duplex Steel Flat Bars are partially magnetic due to their ferritic phase. While not as magnetic as pure ferritic steels, they may exhibit some magnetic properties, especially in certain conditions.
These Duplex Steel Flat Bars find extensive use in industries where high strength and resilience to harsh conditions are essential. You’ll often see them in offshore platforms, marine engineering, heat exchangers, and chemical processing equipment. Their corrosion resistance and robust mechanical strength make them ideal for structural and architectural projects, such as bridges and support frameworks. In the oil and gas industry, these bars are vital components in pipelines, valves, and pressure vessels. Their reliable performance in both fresh and saltwater settings makes them a go-to choice for coastal infrastructure and shipbuilding endeavors.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
