Inconel 725 Round Bar Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies inconel 725 round bar (N07725) from ready stock in Mumbai, to customers across India and in more than 40 export markets.
Round bar is the starting stock for machined and forged parts, so straightness, surface condition and through-thickness properties govern how it performs downstream.
Inconel 725 is the age-hardenable version of 625, giving high-strength sour-service parts that still resist chlorides.

Composition limits for Inconel 725. These are specification limits for the grade, not measured values for a lot; the mill test certificate supplied with your order states the actual analysis.
Mechanical and Physical Properties
Aged tensile strength above 1170 MPa with yield near 830 MPa, while retaining the pitting and chloride cracking resistance of alloy 625.
Industry Applications
| Industry | Typical use |
|---|---|
| Oil and gas | Hangers, packers, landing nipples and sour-service completion hardware. |
| Marine | High-strength seawater fasteners and shafting. |
| Chemical processing | High-strength components in chloride service. |
| Power generation | Fasteners in corrosive high-load duty. |
| Subsea | Connectors, valve components and tensile-loaded hardware. |
Testing and Certification
Every consignment ships with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. Depending on the specification we can add positive material identification, ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM G28 or A262, and third-party inspection release from Lloyd's Register, Bureau Veritas, SGS or TUV.
Aurico Alloys LLP operates an ISO 9001:2015 quality management system, and can certify material to NACE MR0175 / ISO 15156 for sour service where the grade permits.
