Chung Metal Da Nang provides Haynes 625 Bars & Rods, a superalloy made of nickel‑chromium‑molybdenum‑tungsten renowned for its superior corrosion resistance and satisfactory strength over a broad spectrum of temperatures. Alloy 625 is strengthened by solid solution and finds applications in severe environments such as sea water, chemical processing, and oxidation at elevated temperatures. Our rods and bars are produced under strict control of chemical composition, heat treatment, and finish for ensuring performance and longevity even under corrosive or cyclic loading conditions. Such products find usage where resistance to corrosion and high temperature strength are critical considerations.
Haynes 625 generally has approximately 58% nickel, 20‑22% chromium, 8‑10% molybdenum, 3‑5% tungsten, and balance iron, together with minor additions of other elements (e.g., small carbon, manganese, silicon, aluminium, titanium) for property enhancement. It is not age-hardening; its strength is derived from solid solution and cold work. Room temperature tensile strength is high (usually ~800‑900 MPa in stronger tempers), yield strength lower, elongation fair (dependent on temper and cross section). Density is approximately 8.44 g/cm³. Good fatigue resistance, oxidation and corrosion resistance (including chloride and pitting resistance).
Haynes 625 bars and rods exhibit excellent performance in high-temperature environments due to their superior resistance to oxidation, carburization, and thermal-fatigue, maintaining strength and integrity up to 2000°F (1093°C).
Yes, Haynes 625 rods can be customized in size and length according to specific requirements, offering flexibility for various applications in industries like aerospace, chemical processing, and more.
To maintain Haynes 625 bars, regularly clean them to remove contaminants, avoid exposure to extreme temperatures, and store them in a dry, controlled environment to prevent corrosion and degradation.
Haynes 625 Bars & Rods are commonly found in marine conditions, chemical processing hardware (like piping, valves, pumps), nuclear reactor parts, heat exchangers, exhaust systems, and pollution control hardware. Also in aerospace, oil & gas, and industrial furnaces where a high temperature corrosion, oxidation, and severe chemical exposure resistance is needed. Adequate for parts that need to retain mechanical strength in harsh environments and under fatigue loading, e.g., fasteners and bolting in seawater, or structural components that are exposed to damp or corrosive atmospheres.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
