High Resistance to Corrosion and High Temperature Inconel 625 Tubes
Established in the year 2006, Eramets Steel Alloys Pvt. Ltd. is a top name in the manufacturing and supplying of seamless and welded ASTM B704 UNS N06625 Inconel 625 tubes from India. Using the latest technology, we make our seamless tubes using the process of an arc furnace. The tubes are supplied in straight lengths and U bends. Coils are also supplied as per customer requirement. As per customer drawings, we manufacture tubes.
Inconel 625 being a strong Nickel base alloy, shows great resistance to corrosion, heat and high temperatures. We issue a Mill Test Certificate (MTC) for each batch of tubes supplied. Thus, customers can have complete traceability of tubes for critical applications.
Trusted Supplier of Inconel 625 Tubes
We have well established business relationships with various EPC contractors, OEM’s, Heat exchanger fabricators, Instrumentation & Offshore Engineering Companies from India and other countries.
We assure the same quality and same documentation for small quantity tubes for Instrumentation and large quantity tubes for a project.
Before shipping the tubes are bent to U shape (if required), cut to length (if required) and/or end finished (if required) and then packaged.
Why is Inconel 625 so Special?
Being a Ni based alloy with Mo and Nb gives Inconel 625 special properties. Some of the properties include great strength, high temperature resistance and corrosion resistance. Also, Inconel 625 has good properties over a wide range including strength and properties at elevated and cryogenic temperatures.
High Strength – Exceptionally high levels of tensile strength, resistance to creep and fatigue across the entire temperature spectrum.
Pitting & Crevice Corrosion Resistance – Increased corrosion resistance to chlorides is provided by the presence of molybdenum.
Stress Corrosion Cracking Resistance – Resistant to stress corrosion cracking by chloride environments, where stainless steel tubes may stress corrosion crack.
Oxidation & Heat Resistance – Exceptional strength at elevated temperatures, and resists scaling.
Weldability – Easily welded and formed, retains corrosion resistance.
Seamless and Welded Inconel 625 Tubes
Seamless tubes
B444 and SB444 provide the chemistry and mechanical and chemical properties of seamless tubes, respectively. Seamless tubes are drawn or pilgered from a solid hollow stock and thus have no weld seams. They are used in several industries including aerospace, hydraulic systems, and heat exchangers, to name a few.
Welded Tubes
Chemistry and mechanical properties of welded tubes are given in SB704. Resistance welding of strips of stainless steel is used to fabricate B704 tubes without a filler metal. Following cold working and annealing, they are employed in several heat exchangers and condensers.
Inconel 625 Grades 1 and 2
SB444 defines the two grades as Inconel 625 Grades 1 and 2, respectively. Grade 1 has higher strength and is employed for services below 593°C (1100°F). Grade 2 has better properties at elevated temperatures and is employed for services above 593°C. What is your design temperature?

How We Manufacture Inconel 625 Tubing in India
Each Inconel 625 tube undergoes a controlled process to conform to ASTM B444 or B704 and your requirement:
1. Checking of chemistry, heat number and traceability is done for hollows and strips.
2. Forming is done by cold drawing or pilgering seamless tubes and roll forming and welding without filler metal for welded tubes.
3. Heat treatment is done by annealing for Grade 1 or solution annealing for Grade 2.
4. Finishing is done by straightening, pickling or bright annealing, and cutting to the exact length; U-bending or coiling is done as required.
5. Non-destructive tests, hydrostatic tests and mechanical and dimensional tests are done.
6. Each tube is marked with grade and size, standard and heat number, capped, and then packed.

ASTM B444 UNS N06625 Nickel Alloy 625 Seamless Tubing Supplier
At Eramets Steel Alloys, the Inconel 625 tube is widely recognized as one of the most reliable and high-performance materials used in the nuclear industry. Our premium quality Inconel 625 seamless tubes, Inconel 625 annealed tubes, and Alloy 625 tubing are extensively used in critical applications such as steam generators, reactor cores, control rod components, and nuclear waste reprocessing systems.
India's largest stock of UNS N06625 Tube according to international standards ASTM B751/ ASME SB751, ASTM B829/ ASME SB829, ASTM B775/ ASME SB775, ASTM B705/ ASME SB705, ASTM B704/ ASME SB704
The growing demand for UNS N06625 tubes in nuclear power plants is driven by their exceptional resistance to extreme environments. These nickel-based alloy 625 seamless tubes are engineered to withstand high temperatures, intense radiation, and aggressive corrosive conditions, making them an ideal choice for nuclear steam generator tubing and reactor systems.
In nuclear-powered steam generators, basic thermodynamic principles govern heat transfer and energy conversion. The materials used in these systems, including Inconel 625 tubing, must deliver outstanding thermal stability and structural integrity. Our Alloy 625 seamless tubes are specifically designed to perform under these demanding conditions, ensuring long-term durability and safety. Inconel 625 Tube Supplier
One of the key advantages of Inconel 625 pipes and tubes is their superior corrosion resistance. These tubes resist oxidation, pitting, and crevice corrosion even when exposed to high-pressure water and harsh chemical environments over extended periods. This makes Inconel 625 heat exchanger tubes highly suitable for long service life in nuclear applications.
Within the nuclear reactor core, where heat is continuously generated due to nuclear reactions, materials must maintain their mechanical strength under elevated temperatures. Inconel 625 seamless tubing excels in such environments due to its high tensile strength, excellent fatigue resistance, and remarkable toughness. Even under extreme thermal stress, the mechanical properties of Alloy 625 tubes remain stable and reliable.
