Description
Inconel 625 Round Bars
Inconel 625 Round Bars is a Nickel Chromium Molybdenum alloy with an addition of Niobium. Inconel 625 is a High Strength, Highly Corrosion Resistant. It is used in applications like aerospace, oil and gas, automotive, marine, chemical processing and nuclear industries where strength at high temperature are required. Inconel 625 also has resistance to various aqueous media causing localized corrosion, stress corrosion cracking and other forms of attack.
It is known as ASTM B446 UNS N06625 and also as W.NR. 2.4856 .
The addition of molybdenum acts with the niobium to stiffen the alloy matrix, providing a high strength without a strengthening heat treatment. The alloy resists a wide range of corrosive environments and has a good resistance to pitting and crevice corrosion. Alloy 625 is used in chemical processing, aerospace and marine engineering oil & gas, pollution control equipment and nuclear reactors.
Grade 1 (Annealed)—Material is normally employed in service temperatures up to 1100 °F (593 °C).
Grade 2 (Solution Annealed)—Material is normally employed in service temperatures above 1100 °F (593 °C) when resistance to creep and rupture is required.
Grade 3 (Solution Annealed and Cold Worked) Material is normally employed in services where higher strengths are needed.
