Inox Steel India is a leading manufacturer, stockist, and global exporter of Nickel Alloy Tubes conforming to ASTM B163, ASTM B167, and ASTM B444, covering high-performance alloys such as Inconel (625, 600, 601, 825), Monel (400, K500), and Hastelloy (C22, C276, B3). With a strong supply footprint across GCC, Middle East, Africa, Europe, North America, and South America, we produce heat-resistant, corrosion-resistant nickel tubes engineered for the most demanding industrial environments.
Our manufacturing facility follows stringent metallurgical controls, ensuring every tube meets high pressure, high temperature, and highly corrosive service conditions required in chemical, petrochemical, power, oil & gas, marine, and pollution-control systems. Backed by ISO 9001, PED, IBR & EN 10204 3.1/3.2 certifications, Inox Steel India remains a trusted name for critical-application nickel tubes worldwide.
Nickel alloy tubes are precision-engineered tubular products manufactured from special high-nickel alloys designed to withstand extreme temperatures, corrosive chemicals, seawater, high pressure, oxidation, carburization, and pitting far beyond the capabilities of stainless steels.
Unlike conventional steel, nickel alloys maintain tensile strength, metallurgical stability, and surface integrity at elevated temperatures up to 1100 °C, making them essential for heat-intensive and chemically aggressive processes.
Nickel alloy tubes are selected for:
These tubes are engineered for longevity in conditions where stainless steel, duplex steel, or carbon steel tubes cannot survive.
Inox Steel India manufactures Nickel Alloy Tubes using five controlled production routes depending on grade, application, and client requirement:
This ensures every tube leaving the plant performs flawlessly under extreme working conditions.
🔹 Inconel Alloys (625, 600, 601, 825)
