Alloy 625 / UNS N06625 / W.NR. 2.4856

Tsanangudzo

Alloy 625 is nickel-chromium-molybdenum alloy iyo inoshandiswa pakusimba kwayo kwepamusoro, kusimba kwepamusoro uye yakanakisa kusakara. Simba reiyo alloy 625 rinobva mukuomarara kwe molybdenum uye niobium pane yayo nickel-chromium matrix. Kunyangwe iyo alloy yakagadziridzwa kusimba kwekushisa kwepamusoro, kuumbwa kwayo kwakanyanya kusanganiswa kunopawo nhanho yakakosha yeyakajairwa corrosion kuramba.

Maindasitiri uye Zvishandiso

Alloy 625 inoshandiswa mumaindasitiri akasiyana siyana, anosanganisira mota, marine, aerospace, oiri uye gasi, kugadzira makemikari uye nyukireya. Mashandisirwo ekupedzisira ekushandisa anosanganisira kupisa kupisa, mabhero, majoini ekuwedzera, masisitimu eutsi, zvimisikidzo, kukurumidza kubatanidza masisitimu uye mamwe akawanda maapplication anoda simba uye kuramba kurwisa nharaunda dzinoparadza.

Resistance to Corrosion

Alloy 625 ine kumira kwakanaka kune oxidation uye kuyera pakupisa kwakanyanya. Pa1800 ° F, kuyera kuramba kunova chinhu chakakosha mubasa. Iyo yepamusoro kune akawanda akawanda ekushisa alloys pasi pe cyclic kudziyisa uye kutonhora mamiriro. Iko kusanganiswa kwezvinhu zvakasanganiswa mualloy 625 inoita kuti ikwanise kumira kwakasiyana siyana kwenzvimbo dzinotyisa. Iko kunenge kusina kurwiswa munzvimbo dzakapfava, dzakadai semvura yakachena uye yegungwa, isina kwayakarerekera pH nharaunda, uye alkaline midhiya. Iyo chromium yemukati yeiyi alloy inoguma nekupikisa kwepamusoro kune oxidizing nharaunda. Iyo yakakwira molybdenum yemukati inoita alloy 625 inoshingirira kugomba uye kukoromoka kwegora.

Kugadzira uye Kupisa Kurapa

Alloy 625 inogona kuumbwa uchishandisa akasiyana siyana anotonhora uye anopisa ekushanda maitiro. Alloy 625 inopikisa deformation pakupisa kwekushanda, saka mitoro yakakwirira inodiwa kuti igadzire zvinhu. Kugadzira kupisa kunofanirwa kuitwa mukati metembiricha ye1700 ° kusvika 2150 ° F. Munguva yekushanda kunotonhora, basa rezvinhu rinoomesa nekukurumidza kupfuura zvechinyakare austenitic simbi isina tsvina. Alloy 625 ine matatu ekurapa kupisa: 1) mhinduro annealing pa 2000/2200 ° F uye mhepo inodzima kana kukurumidza, 2) annealing 1600/1900 ° F uye mhepo inodzima kana kukurumidza uye 3) kudzoreredza kunetseka pa 1100/1500 ° F uye mweya quenching. . Solution annealed (giredhi 2) zvinhu zvinowanzo shandiswa pamaapplication ari pamusoro pe1500°F uko kuramba kunyura kwakakosha. Soft-annealed material (giredhi 1) inowanzo shandiswa pakudzikira tembiricha uye ine musanganiswa wakakwana wekusimba nekutsemuka.
