Sadiki Metals, Kinshasa, Congo manufactures and supplies Duplex Steel Round Bars. Duplex Steel is known for its strength and corrosion resistance. Round bars are widely used in the following industries: oil and gas, marine, and chemical processing industries. Here, durability and reliability are of prime importance. The quality and satisfaction of the customer are guaranteed. We guarantee that their duplex steel round bars are of high industry standards for clients to receive the best quality material for their projects.
Duplex steel round bars are stainless steel alloys which have both austenitic and ferritic microstructures. Thus, they result in high strength along with excellent corrosion resistance. Normally, it is made up of about 22% chromium, 5% nickel, and 3% molybdenum, which has very good mechanical properties. Making them suitable for various applications in industries such as oil and gas, chemical processing. And marine environments. The unique composition allows duplex steel to withstand stress corrosion cracking and pitting. While also providing high durability and weldability. Overall duplex steel round bars are an reliable choice for demanding environments. Where both strength and resistance to corrosion are important.
