Inconel 625 Round Rods
Inconel 625 Round Rods are high-performance nickel-chromium-molybdenum alloy rods known for their exceptional strength, corrosion resistance, and versatility in extreme environments. Manufactured and supplied by Rose Metal Industries, these round rods are widely used in industries requiring resistance to high temperature, oxidation, and corrosive media. Our products are distributed across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), Andaman & Nicobar Islands, and exported globally, meeting both domestic and international project requirements..
These Inconel 625 Round Rods are composed of 58% minimum nickel, 20–23% chromium, 8–10% molybdenum, 3–4.5% niobium + tantalum, with trace amounts of iron, cobalt, and other elements. This carefully engineered chemical composition ensures outstanding corrosion resistance against pitting, crevice corrosion, and stress-corrosion cracking in chloride-rich and oxidizing environments, making it ideal for marine, chemical, and aerospace applications..
Mechanically, Inconel 625 Round Rods exhibit a tensile strength of 827–1241 MPa and a yield strength of 414–552 MPa, with elongation values ranging from 30–45%. These rods maintain structural integrity at elevated temperatures up to 980°C and possess excellent fatigue strength. The alloy’s exceptional toughness and creep resistance allow it to perform reliably in high-pressure, high-temperature applications such as chemical reactors, gas turbines, and marine engineering components..
Rose Metal Industries supplies Inconel 625 Round Rods in various diameters and lengths, offering hot-rolled, forged, and polished finishes to suit fabrication requirements. Standard dimensions range from 6 mm to 200 mm in diameter, with custom sizes available on request. These rods are supplied with mill test certificates (MTC), PMI reports, and comply with international standards such as ASTM B446, ASME SB446, and AMS 5662, ensuring quality and reliability for critical applications..
