Inconel 625 Nickel Alloy Forging Ring UNS NO6625 Corrosion Resistant
Nickel Alloy Forging Ring Inconel 625 Offshore Oil Platform Highmechanical Parts
Nickle Alloy Forging Ring are the most common in forged metals. Through open die forging, the metal is formed into something that's shaped like a doughnubefore it's heated between 400 and 700'c. Next, it's placed on a mandrel or idler rol that increases the steel ring's diameters and reduces thethickness of its walls. You can find them in machinery and equipment, vehicles, pipes and valves, and other hardware. Almost all vehicles and otherheavy machinery make use of them because they are durable and easy to replace and look for.
Nickel Alloy 625 (UNS NO6625) is a material with excellent resistance to pitting, crevice, and corrosioncracking. This alloy is highly resistant in a wide range oforganic and mineral acids, and it exhibits good hightemperature strength. Excellent mechanical properties at both extremely lowand extremely high temperatures. Outstanding resistance to pitting, crevice corrosion, and intercrysta ine corrosion. Almost complete freedom from chloride induced stress corrosion cracking. High resistance to oxidation at elevated temperaturesup to 1050°C. Good resistance to acids, such as nitric, phosphoricsulfuric, and hydrochloric, as wel as to alkalis makespossible the construction of thin structura parts ofhigh heat transfer.
Applications
- Components where exposure to sea water and higrmechanical stresses are required.
- Oil and gas production where hydrogen sulfide anoelementary sulfur exist at temperature in excess of150°C.
- Components exposed to flue gas or in flue gasdesufurization pants.
- Flare stacks on offshore oil platforms.
- Hydrocarbon processing from tar-sand and oil-shale
- Recovery projects.
