Aung Metals, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, has built a solid reputation for crafting high-quality Duplex Steel Bright Bars that adhere to international standards. Thanks to cutting-edge technology and rigorous quality control measures, Aung Metals guarantees that every bar boasts exceptional strength, durability, and resistance to corrosion. The company serves a variety of industries, including oil and gas, chemical processing, construction, and marine applications. Their Duplex Steel Bright Bars come in a range of dimensions and finishes, providing customers with customized solutions for demanding environments where reliability and performance are crucial.
These Duplex Steel Bright Bars are primarily made up of chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen, which creates a fantastic balance between austenitic and ferritic structures. This unique composition gives them outstanding mechanical strength, high yield and tensile strength, and remarkable resistance to pitting and stress corrosion cracking. With a tensile strength of around 620 MPa and a yield strength of about 450 MPa, these bars are built to withstand high-pressure and high-temperature conditions. Their balanced microstructure not only enhances toughness but also maintains formability during machining and fabrication.
