These Duplex Steel Flat Bars are made up of about 22% chromium, 5% nickel, and 3% molybdenum, along with small amounts of nitrogen, manganese, and silicon. This specific composition strikes a perfect balance between corrosion resistance and mechanical strength. They showcase a yield strength ranging from 450 to 550 MPa and a tensile strength between 620 and 850 MPa, with hardness levels falling between 280 and 330 HB. The microstructure, featuring nearly equal parts of austenite and ferrite, grants excellent toughness, fatigue resistance, and dimensional stability, making these bars perfect for demanding industrial uses.

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.
Duplex Steel Flat Bars find their place in industries that require both high strength and corrosion resistance. You’ll often see them in applications like chemical processing equipment, heat exchangers, pressure vessels, and structural components in marine and offshore settings. They’re also utilized in oil and gas pipelines, desalination plants, pulp and paper manufacturing, and construction projects that face harsh conditions. The combination of impressive mechanical strength and resistance to stress corrosion cracking ensures long-lasting durability, reliability, and lower maintenance costs, making Duplex Steel Flat Bars a go-to choice for critical engineering needs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
