Inconel 625 Pipes & Tubes
Inconel 625 is a high-performance nickel-based alloy known for its exceptional corrosion resistance, high strength, and versatility. Inconel 625 pipes and tubes are widely used in various industries, including aerospace, chemical processing, and marine applications, where resistance to harsh environments and high temperatures is crucial.
Inconel pipes and tubes are among the most widely used types of metal piping in many industries, such as oil and gas, petrochemical, power generation, aerospace, and defense. Inconel 625 Pipes, in particular, are extremely durable due to their high nickel and chromium levels. They are also highly resistant to corrosion and oxidation, making them a great choice for many applications.

Differences between Inconel and Hastelloy
Inconel and Hastelloy are both nickel-chromium-molybdenum-based alloys. They are all corrosion-resistant and extremely strong metals. Hastelloy has greater molybdenum content than Inconel, although Inconel has a higher chromium concentration. This sets them apart in terms of corrosion resistance in different situations.
