Dhruv Metals is a leading manufacturer and exporter of Haynes 625SQ Bars and Rods in Hyderabad, India. Haynes 625SQ (Special Quality) is a high-strength, nickel-based alloy specifically made for superior fatigue resistance and weldability. It offers exceptional corrosion, oxidation, and stress cracking resistance across a wide temperature range. With its enhanced cleanliness and low inclusion content, the SQ version is ideal for applications that require strict control over mechanical integrity. Dhruv Metals supplies Haynes 625SQ bars according to AMS 5666 and ASTM B446 standards, catering to the aerospace, marine, and chemical processing sectors.
Haynes 625SQ contains nickel (58% minimum), chromium (20–23%), molybdenum (8–10%), niobium (3.15–4.15%), and iron (~5%). It has a tensile strength of 827–965 MPa and yield strength of 414–690 MPa, with elongation up to 30%. This alloy keeps its toughness and ductility across temperatures from cryogenic up to 980°C (1800°F). The SQ variant undergoes special treatment for low residual inclusions and high fatigue resistance. It is non-magnetic and offers great fabricability, making it suitable for welding and machining in critical service applications.
Yes, Haynes 625SQ rods can be customized in size and length according to specific requirements. Manufacturers typically offer tailored dimensions for various applications in industries requiring precise specifications.
Haynes 625SQ Rod is typically available in diameters ranging from 0.125" (3.175mm) to 3.000" (76.2mm), with custom sizes possible. Lengths usually range from 12" to 20' (3.66m).
Haynes 625SQ bars and rods offer excellent performance in high-temperature environments, with outstanding oxidation and carburization resistance, maintaining strength and integrity at elevated temperatures up to 1800°F (982°C).
Haynes 625SQ Bars and Rods are used in jet engine components, marine exhaust systems, subsea equipment, chemical reactors, and heat exchangers. Their high corrosion resistance makes them ideal for acidic environments, flue gas scrubbers, and nuclear water systems. In aerospace, they are found in airframe structures, turbine blades, and ducting. The SQ grade is especially useful for welded structures and applications with cyclic loading due to its excellent fatigue performance. Dhruv Metals ensures Haynes 625SQ meets strict quality standards for the needs of critical, high-performance systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
