Semih Metals, located in Istanbul, Turkey, has built a solid reputation as a manufacturer and supplier of top-notch Incoloy square bars, catering to a diverse array of critical industries. With a commitment to precision engineering and dependable performance, Semih Metals produces Incoloy square bars that adhere to rigorous international standards for durability, corrosion resistance, and mechanical strength. The company draws on its deep metallurgical knowledge and cutting-edge manufacturing techniques to deliver tailored solutions for challenging environments, earning the confidence of clients in fields like marine engineering, chemical processing, power generation, and oil and gas.
Incoloy square bars are generally made from a nickel-iron-chromium base alloy, with specific grades such as Incoloy 800 and 825 incorporating additional elements like molybdenum, copper, and titanium. These bars are known for their outstanding resistance to oxidation, carburization, and a variety of acidic and corrosive conditions. Depending on the grade, their mechanical properties feature tensile strengths ranging from 500 to 750 MPa, yield strengths between 200 and 450 MPa, and elongation values of 30–45%, striking a perfect balance between strength and ductility. The square shape ensures even stress distribution and remarkable stability, making them perfect for structural and load-bearing uses.
