What is the composition of Inconel 625?
What is the composition of Inconel 625?
This superalloy is composed mainly of nickel (58% min.) followed by chromium, and molybdenum, niobium, iron, tantalum, cobalt, and trace amounts of manganese, silicon, aluminium, and titanium. Inconel 625 also commonly goes by the names: Haynes 625, Altemp 625, Nickelvac 625, and Nicrofer 6020.
What is the difference between Inconel 625 and Alloy 625?
Alloy 625 has excellent fatigue strength and stress – corrosion cracking resistance to chloride ions. INCONEL® 625 LCF is a variant of INCONEL® 625. This means that the alloy has improved cycle fatigue properties and better thermal fatigue resistance.
Is Inconel 625 a nickel alloy?
Nickel Alloy 625, frequently called Inconel® 625, is a corrosion and heat-resistant Nickel-based alloy. It is alloyed with Chromium and Iron, along with Niobium-Tantalum and Molybdenum for increased toughness and strength.
What is alloy 625 material?
Description. Alloy 625 is a nickel-chromium-molybdenum alloy that is used for its high strength, high toughness and excellent corrosion resistance. The strength of alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix.
What is 625 metal?
Inconel 625 is a nickel-base alloy used both for its high strength and outstanding aqueous corrosion resistance. The strength of alloy 625 is primarily a solid solution effect from molybdenum and columbium. Alloy 625 has excellent weldability and is frequently used to weld AL-6XN® alloy.
What is the hardness of Inconel 625?
Inconel 625
| Alloy state | Tensile strength Rm N/mm² | Brinell hardness HB |
|---|---|---|
| 625 | 760 | ≤220 |
Is Inconel 625 easy to machine?
Nickel & cobalt base corrosion, temperature and wear-resistant alloys, such as Inconel 625, are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates.
Is Inconel 625 magnetic?
What is Inconel 625? Inconel Alloy 625 is a non-magnetic, corrosion and oxidation resistant, nickel-chromium alloy. Inconel 625 has tremendous resistance to a wide range of unusually severe corrosive environments including high-temperature effects such as oxidation and carburization.
Is Inconel 625 ferromagnetic?
But then most people I talked to, including some senior, experienced NDT technician said that due to the substantial amount of Nickel (58% ) with some iron (5%) in the alloy, that makes inconel 625 ferromagnetic.
What is Alloy 625?
Alloy 625 is an austenitic nickel- chromium-molybdenum-niobium alloy possessing a rare combination of outstanding corrosion resistance coupled with high strength from cryogenic temperatures to 1800°F (982°C).
What are the chemical properties of Inconel 625?
For instance, a standard AMS 5666 or UNS N06625 variant of Inconel 625 may contain 58% nickel, 22% chromium, and 3.5% niobium. Heat treatment of alloys is necessary to increase material toughness. In the case of Inconel 625, the following treatments may be applied:
What is N06625 alloy?
Specification Sheet: Alloy 625 (UNS N06625) W. Nr. 2.4856 An Austenitic Nickel-Chromium-Molybdenum-Niobium Alloy with Outstanding Corrosion Resistance and High Strength from Cryogenic Temperatures to 1800°F (982°C)
What is the hot-working temperature range for Alloy 625?
The hot-working temperature range for Alloy 625 is 1650– 2150°F (900–1177°C). Heavy working needs to occur as close to 2150°F (1177°C) as possible, while lighter working can take place down to 1700°F (927°C). Alloy 625 can be cold-formed by the standard shop fabrication practices.
