Inconel 625 (Nickel Alloy 625 / UNS N06625) High-Simba Corrosion-Resistant Pipe and Tube - BLOG

Alloy Profile uye Industrial Basa

Inconel 625, inozivikanwawo seNickel Alloy 625 kana UNS N06625, iine nickel yakasimba-solution-strengthened nickel{4}}chromium-molybdenum-niobium alloy yakagadziridzwa kuitira kushanda uko kunenge kuine ngura uye tembiricha yakanyanyisa. Inochengetedza simba rakasiyana, kurwisa, uye kugadzikana kweoxidation kubva kune cryogenic mamiriro kusvika ku1000℃(1832℃F).
Giredhi iri rinoshandiswa zvakanyanya mumidziyo yemugungwa, masisitimu ekugadzira makemikari, mayuniti ekudzora kusvibiswa kwemhepo, mareactors enyukireya, uye majet engine exhaust assemblies-maapplication apo hunhu hwakanaka uye corrosion control inofanira kushanda pamwe chete. Yayo Ni{2}}Cr-Mo-Nb balance inogadzira yega-healing oxide film uye inodzvanya kurwiswa kwenzvimbo kunyangwe muine acidic uye chloride-yakapfuma.

Kemikari Dhizaini uye Metallurgical Hunhu

Element	% Range	Function
Nickel (Ni)	Yakakura kudarika kana yakaenzana ne58.0	Base matrix; ngura uye kugadzikana kwekupisa
Chromium (Cr)	20.0–23.0	Inogadzira passive oxide yekudzora oxidation
Molybdenum (Mo)	8.0–10.0	Inorambira gomba uye kukoromoka
Niobium (Cb + Ta)	3.15–4.15	Inosimbisa sarudzo yakasimba; inodzivirira creep deformation
Simbi (Fe)	Zvishoma pane kana kuenzana ne5.0	Inovandudza maitiro ekugadzira
Kabhoni (C)	Zvishoma pane kana kuenzana ne0.10	Inodzora kuumbwa kwecarbide
Mn / Si / S	Zvishoma pane kana kuenzana ne0.5 / 0.5 / 0.015	Chengetedza kuchena uye weld quality

Iko kusanganiswa kwe molybdenum ne niobium kunopa simba guru pasina kunaya kwemvura kuoma, zvichiita kuti kugadzirwa kuri nyore uye kushanda kwakadzikama mukati menguva yakareba-kunyanya kupisa. Iyi microstructure inochengeta tsanga dzakatsetseka uye inodzivirira tsanga-kumonereka kwemuganhu mushure mekunama kana kupinza.

Mechanical Kuvimbika pasi peTembiricha uye Stress

Property	Metric (min)	Imperial (min)	Tsanangudzo
Tensile Simba	827 MPa	120 ksi	Inochengetedza kuvimbika kune 870 degree
Goho Simba (0.2 %)	414 MPa	60 ksi	Inoramba deformation pasi pemutoro
Elongation	Yakakura kupfuura kana yakaenzana ne30%	Yakakura kupfuura kana yakaenzana ne30%	Yakanakisa ductility post-kuratidzwa
Kuoma	Zvisingasviki kana zvakaenzana ne95 HRB	Zvisingasviki kana zvakaenzana ne95 HRB	Inopa machinability uye formability

Mune cyclic sevhisi mamiriro, Inconel 625 inochengeta kuneta simba uye dimensional kugadzikana nekurasikirwa kusingakoshi mukudzora oxidation.

Manufacturing Process uye Heat Treatment

Mapombi nemachubhu anogadzirwa kuburikidza nekupisa extrusion kana kutonhora kudhirowa uyezve mhinduro inonyudzwa pa1090-1150 dhigirii (1995-2100 dhigirii F) ichiteverwa nekukurumidza kudzimwa kudzoreredza kusaita ngura. Welded mhando dzinogadzirwa neTIG kana plasma maitiro pasi peinert gasi kudzivirira.
Kunyatso kuumba uye kutonhora saizi inochengetedza kuwirirana kwemadziro, uku kunhonga uye kupenya kupenya kunomutsa zvakare inodzivirira Cr₂O₃ pamusoro firimu. Kugadzira uye kuongorora kunoenderanaASTM B444, B705, uye B704mipimo.

Corrosion Resistance mhiri kweMedia

The alloy's dual action-nickel-chromium oxide film for oxidizing conditions and molybdenum-niobium reinforcement yekuderedza nharaunda{3}}inoipa kugadzikana kwekemikari kwakafara:

Mvura yegungwa uye chlorides:Inorambira kugomba, kutsemuka, uye kushushikana-kukoromoka.
Oxidizing acids (nitric, chromic):Chromium inochengetedza oxide kunamatira patembiricha.
Kuderedza acids (hydrochloric, phosphoric):Molybdenum inodzivirira kurwiswa kwenzvimbo.
Gasi rakavava (H₂S):Yakagadzikana kurwisa sulfide kusagadzikana kupaza kwemafuta uye gasi sevhisi.
Kuwedzera-temperature oxidation:Inopikisa kuyera uye kurasikirwa kwesimbi kusvika ku1000 degree.

Dimensional Range uye Chigadzirwa Chekupa
