What is Inconel 625?

Inconel 625 is austenitic super-alloy made of nickel base. It has excellent properties of resistance to corrosion and oxidation. It has great strength and toughness due to the presence of columbium and molybdenum. It has high temperature resistance of up to 2000 degrees F and its non-magnetic nature gives it use in environments where both oxidation and corrosion resistance are required.

Inconel 625 has a wide array of applications such as in marine environments, hot sections of jet engines and corrosive and high-temperature chemical processing atmospheres. Inconel 625 is also good for sea water applications, mooring cables and propeller blades, motors, utility boats, undersea communication cables, springs, seals and other types of marine applications.


Inconel 625 Pipes are nickel-based pipes that offer great strength, excellent fabricability, and outstanding corrosion resistance. These pipes are highly preferred due to their extraordinary service in the temperature range from cryogenic to 1800°F. The versatile and outstanding corrosion resistance of Inconel 625 under a wide range of temperatures and pressures is a primary reason for its wide acceptance in various fields.

Inconel 625 Pipes are extensively used in the aerospace, automobile, chemical processing, oil extraction, oil refining, marine, waste treatment, pulp & paper and power industries. Inconel 625 Pipes have also been used in making Jet Engine Components, Cryogenic Storage Tanks, Commercial Gas Turbines, in Food Processing, Nuclear reactors, and Pollution control equipments.

Case Study:

We have a client in Netherlands, who required Inconel 625 Pipes for supply in Saudi Arabia. He is a trader of Inconel 625 Pipes. He wanted to buy the pipes at the low price. Thus brought Pipes from China, but the pipes failed the test and the nickel composition was less than acceptable. Later he brought the Pipes from India but was duped by a dummy company. The company supplied Carbon Steel instead of Inconel 625 Pipes. The customer was under heavy pressure from the end user. He was facing a legal prosecution as had under contract obliged to complete the project within a specific time frame.

He went to several big European brands but all of them offered delivery of 12-15 weeks. He again resorted to buying from a few select Indian and Korean Suppliers. We got the mail. We replied within 25 minutes. He asked for a Third Party Inspection and a 3.2 Certification. We accepted the terms. Within a span of 90 minutes we had the sales contract from the client. We supplied the goods and the client was relieved from the heavy pressure he was under. Now the client normally buys from big Manufacturers , but gives us opportunities for urgent needs and maintenance projects.

We have a few happy stories we share with our users. We aim for a lot more. Hope we can share your case story with your next purchase.
