Our Duplex Steel Round Bar provides good resistance to chloride stress corrosion, thermal conductivity and has a low coefficient of thermal expansion as well. We develop Super Duplex Bars such that they are usable in aggressive environments while retaining the properties. These round bars are available in different finishes such as black, polish and bright. They are also available in various forms, hence one can get it as per their suitability and budget. This Duplex Steel Round Bar is available basically in two major grades Super Duplex UNS S32750 and Super Duplex UNS S32760. Our Super Duplex Steel Round Bar are manufactured for the usage which requires exceptional strength and resistance to corrosion like chemical processing, petrochemical, and seawater equipment etc.
Super Duplex 2507 Round Bar is manufactured for applications that demand outstanding tensile strength and superior resistance to corrosion as well. The UNS S32750 Super Duplex Steel Bar contains 25% chromium, 4% molybdenum, as well as 7% nickel in its alloy. Our Duplex 2507 alloy is used at temperatures exceeding 600 degrees F. This is because of exposure at a temperature range over 600 degrees F and extended use of the Super Duplex Stainless Steel S32760 Hollow Bar at high-temperature settings could reduce both the hardness as well as corrosion resistance properties of alloy 2507.
