Inkcazo

I-alloy 625 yi-nickel-chromium-molybdenum alloy esetyenziselwa amandla ayo aphezulu, ukuqina okuphezulu kunye nokumelana nokugqwesa okugqwesileyo. Amandla e-alloy 625 avela kwimpembelelo yokuqina kwe-molybdenum kunye ne-niobium kwi-nickel-chromium matrix yayo. Nangona i-alloy yaphuhliswa ukomelela kobushushu obuphezulu, ukubunjwa kwayo okudityanisiweyo okuphezulu kukwabonelela ngenqanaba elibalulekileyo lokuxhathisa umhlwa ngokubanzi.

Amashishini kunye nezicelo

I-alloy 625 isetyenziswa kumashishini ahlukeneyo, kubandakanywa iimoto, ezolwandle, i-aerospace, i-oyile kunye negesi, ukulungiswa kweekhemikhali kunye nenyukliya. Usetyenziso oluqhelekileyo lokusetyenziswa lubandakanya ukutshintshiselana kobushushu, imivumbo, ulwandiso lwamalungu, iinkqubo zokukhupha umoya, iziqhoboshi, izifakelo ezikhawulezayo zokudibanisa kunye nezinye izinto ezininzi ezifuna ukomelela kunye nokuxhathisa ngokuchasene neendawo ezinobundlongondlongo.

Ukuxhathisa kwiCorrosion

I-alloy 625 inokumelana kakuhle ne-oxidation kunye nokulinganisa kumaqondo aphezulu. Kwi-1800 ° F, ukuchasana kokulinganisa kuba yinto ebalulekileyo kwinkonzo. Iphezulu kunezinye ezininzi ii-alloys eziphezulu zokushisa phantsi kokufudumala kwe-cyclic kunye neemeko zokupholisa. Ukudityaniswa kwezinto ezidityanisiweyo kwi-alloy 625 iyenza ikwazi ukumelana neentlobo ngeentlobo zemeko-bume ezonakalisayo. Phantse akukho hlaselo kwiindawo ezipholileyo, ezinjengamanzi amatsha kunye nolwandle, i-pH engathathi hlangothi, kunye nemidiya yealkaline. Umxholo wechromium wale alloy uphumela ekuxhathiseni okuphezulu kwiindawo ezine-oxidizing. Umxholo ophezulu we-molybdenum wenza i-alloy 625 ixhathise kakhulu kwi-pitting kunye ne-crevice corrosion.

Ukwenziwa kunye noNyango loBushushu

I-alloy 625 inokusekwa ngokusebenzisa iinkqubo ezahlukeneyo zokusebenza ezibandayo kunye nezishushu. I-alloy 625 iyamelana nokuguqulwa kwamaqondo okushisa ashushu, ngoko ke imithwalo ephezulu iyafuneka ukwenza izinto eziphathekayo. Ukubunjwa okushushu kufuneka kwenziwe ngaphakathi kwinqanaba lobushushu le-1700 ° ukuya kwi-2150 ° F. Ngexesha lokusebenza okubandayo, umsebenzi wezinto eziphathekayo unzima ngokukhawuleza kunezinsimbi ze-austenitic zendabuko. I-alloy 625 ineendlela ezintathu zonyango lobushushu: 1) isisombululo se-annealing kwi-2000 / 2200 ° F kunye nokucima umoya okanye ngokukhawuleza, 2) ukucima i-1600 / 1900 ° F kunye nokucima umoya okanye ngokukhawuleza kunye 3) ukunciphisa uxinzelelo kwi-1100 / 1500 ° F kunye nokucima umoya. . Isisombululo se-annealed (ibanga lesi-2) sisetyenziswa ngokuqhelekileyo kwizicelo ezingaphezulu kwe-1500 ° F apho ukuchasana nokunyuka kubalulekile. I-Soft-annealed material (ibakala 1) iqhele ukusetyenziselwa amaqondo obushushu asezantsi kwaye ineyona ndibaniselwano ilungileyo yokuqina kunye neempawu zokugqabhuka.
