Anucha Metals is a well-respected manufacturer and supplier of Duplex Steel Round Bars based in Bangkok, Thailand. They offer top-notch bars that are celebrated for their impressive strength, resistance to corrosion, and long-lasting durability. Duplex steel cleverly merges the benefits of both austenitic and ferritic stainless steels, resulting in outstanding mechanical properties and remarkable resistance to issues like pitting, crevice corrosion, and stress corrosion cracking. Adhering to international quality standards, Anucha Metals guarantees precise dimensions, a smooth finish, and reliable performance, making their duplex steel round bars perfect for tough industrial, marine, and chemical applications.
These Duplex Steel Round Bars mainly consist of chromium, nickel, and molybdenum, with a touch of nitrogen and manganese to boost their strength and corrosion resistance. This unique dual-phase structure offers high tensile and yield strength, good toughness, and exceptional resistance to corrosion caused by chlorides. In terms of mechanics, duplex round bars excel under high pressure and temperature conditions, while also providing better weldability and machinability compared to traditional stainless steels.
