Metline is a leading manufacturer and supplier of Inconel alloy 625 tube fittings, also widely known as compression or instrumentation fittings in India and worldwide.

UNS N06625 or W.Nr. 2.4856, Inconel 625, also known as Alloy 625, is a nickel-chromium-molybdenum alloy with an addition of niobium. Niobium acts with the molybdenum to stiffen the alloy’s matrix and thereby providing high strength without a strengthening heat treatment. Alloy 625 seamless tubing are widely used both for its high strength and outstanding aqueous corrosion resistance.

Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability, and resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Some typical applications Inconel 625 is used in are chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.
