Anucha Metals, located in Bangkok, Thailand, is a reliable manufacturer and supplier of top-notch Inconel 690 Bars and Rods, crafted for outstanding performance in high-temperature and corrosive settings. Known for our precision, durability, and prompt delivery, we cater to clients in the power generation, nuclear, chemical processing, and marine sectors. Our Inconel 690 products are produced to meet international standards, guaranteeing reliability even in the toughest service conditions. At Anucha Metals, we blend technical know-how, advanced manufacturing techniques, and a customer-centric approach to offer alloy solutions that ensure long-lasting performance and exceptional value.
Inconel 690 Bars and Rods are high-nickel alloys, primarily made up of about 58–61% nickel (Ni), 27–31% chromium (Cr), and 7–11% iron (Fe), along with small amounts of silicon, manganese, and carbon. This unique composition gives them remarkable resistance to high-temperature oxidation and corrosion, particularly in acidic and steam environments. On the mechanical side, Inconel 690 boasts a tensile strength of roughly 414–690 MPa, a yield strength of around 275 MPa, and an elongation of 30–45%. It retains its strength and structural integrity even under high thermal stress, making it perfect for extended use in extreme industrial conditions.

Inconel 690 Bars and Rods find extensive application in industries that require exceptional corrosion resistance, especially in hot, acidic, or steam-rich environments. They are commonly used in nuclear power plants for steam generators, reactor core components, and heat exchangers due to their ability to resist stress-corrosion cracking. In the chemical processing sector, they are utilized in piping systems, condensers, and heaters that come into contact with strong oxidizing agents. The impressive high-temperature performance of Inconel 690 also makes it a great fit for superheaters and gas turbine components.
