Nickel Alloy Forging Discs Inconel 625 Nuclear Industry Reactor
Core Components
Nickle Alloy disc, a thin, projecting metal stripattached to asemiconductor to
dissipateheat. It is widely used incatering and
kitchenware,elevators,chemical equipment,machinery
manufacturing,architectural decoration, metaproducts, automobiles,
pressurevessels and other felds.
Nickel Alloy 625 (UNS NO6625) is a material withexcellent 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.
Fabrication Data:
Alloy 625 can be easily welded and processed by standard shop
fabrication practices, however because the high strength of the
alloy, it resists deformation at hotworking temperatures.
- Hot Forming. 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). Hot-working should occur in uniform reductions to
prevent duplex grain structure
- Cold Forming. Alloy 625 can be cold-formed by the standard shop fabrication
practices. The alloy should be in the annealed condition. Work
hardening rates are higher than the austenitic stainless steels.
- Welding. Alloy 625 can be readily welded by most standard processes
including GTAW (TIG), PLASMA, GMAW (MIG/MAG), SAW and SMAW (MMA). A
post weld heat treatment is not necessary. Brushing with a
stainless steel wire brush after welding will remove the heat tint
and produce a surface area that does not require additional
pickling.
- Machining. Alloy 625 should preferably be machined in the annealed
condition. Since Alloy 625 is prone to workhardening, only low
cutting speeds should be used and the cutting tool should be
engaged at all times. Adequate cut depth is necessary to assure
avoiding contact with the previously formed work-hardened zone.
