Hastelloy C UNSN10002/W.Nr. 2.4819 /ASTM B622

Isishwankathelo

IHastelloy C yingxubevange ekwaziyo ukumelana nomhlwa enezinto ezininzi ezigqwesileyo ezixhathisa kakhulu kwi-oxidizing kunye nokunciphisa okuphakathi. Inokumelana okugqwesileyo koxinzelelo lwe-corrosion cracking kunye nesakhono esilungileyo sempahla yendawo, kwaye inokumelana ne-corrosion eyanelisayo kumajelo amaninzi enkqubo yeekhemikhali, kubandakanywa ukubola okuqinileyo kwesisombululo se-asidi ye-inorganic, i-chlorine kunye nekloridi, i-chlorine eyomileyo, i-asidi ye-formic kunye ne-acetic acid, amanzi olwandle kunye namanzi etyuwa.

CorrUkwahlula ukwahlula

IHastelloy C yimathiriyeli yealloyi esekwe kwi-nickel ephezulu kunye nokumelana nokugqwesa okugqwesileyo. Le ngxubevange inokuxhathisa okulungileyo kwi-oxidizing kunye nokunciphisa ngokulinganayo ukubola, kwaye ibonisa ukuxhathisa okwanelisayo kwi-corrosion kwi-media media media. Ngokukodwa, inokumelana okuphezulu kakhulu nemithombo yeendaba ezonakalisayo ezifana ne-asidi eyomeleleyo, i-alkali eyomeleleyo, amanzi etyuwa, kwaye kwangaxeshanye inokugcina ukusebenza okuzinzileyo phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu lwe-oxidation bume.

Ukongeza, i-Hastelloy C ikwanayo noxinzelelo olugqwesileyo lokuchasana nokuqhekeka kwe-corrosion kunye nobuchule obuhle bokugquma bendawo, kunye nokumelana okubalaseleyo kwi-asidi yesulfuric kunye ne-non-oxidizing acids ezininzi, nto leyo eyenza ukuba ibe ntle kunyango lwemithombo yeendaba ezibandakanya izisombululo ze-asidi ye-inorganic, iklorini kunye nemidiya eyahlukeneyo equlethe ikloridi, iklorini eyomileyo, i-formic kunye ne-acetic acid, amanzi olwandle kunye netyuwa.

Le ngxubevange inekhabhoni ephantsi kakhulu kunye nomxholo wesilicon, onceda ukunciphisa imvula yekhabhoni kunye nezinye izigaba zokungacoceki kwindawo echaphazelekayo yokushisa, ngaloo ndlela igcina ukuxhathisa kwe-weld. Ngexesha elifanayo, ngokulawula umxholo wesinyithi kunye ne-chromium, ukubunjwa kwe-β-phase Ni4Mo kunokuthintelwa, ngokuqhubekayo ukuqinisa ukuxhathisa ukubola.

Ke ngoko, iHastelloy C isetyenziswe ngokubanzi kushishino lweekhemikhali, ishishini lepetrochemical, ishishini lenyukliya, i-aerospace, ukwenziwa kweemoto, ubunjineli baseLwandle, i-biomedicine kunye nezinye iinkalo. Kwezi nkalo, isoloko isetyenziselwa ukwenziwa kwezikhongozeli, izitshintshi zobushushu, iipleyiti zokupholisa iipleyiti, izixhobo zokuvelisa iacetic kunye neemveliso zeasidi, kunye neendawo ezinobushushu obuphezulu.

Unyango lobushushu

Unyango lwesisombululo:

IHastelloy C ifudunyezwa kwisisombululo sobushushu, idla ngokuba phakathi kwe-980°C kunye ne-1100°C.

Igcinwa ixesha elithile ize ipholiswe ngokukhawuleza, ngokuqhelekileyo ngokucinywa kwamanzi okanye ukupholisa umoya.

Le nkqubo inokuphelisa isigaba se-precipitated kwi-alloy kunye nokuphucula iplastiki kunye nokuqina kwezinto.

Ulawulo lwezinga lokupholisa lubalulekile kwiimpawu zemathiriyeli, ukupholisa ngokukhawuleza kakhulu kunokukhokelela ekwandeni kobuqhophololo bemathiriyeli, ngelixa ukupholisa okucothayo kakhulu kunokukhokelela ekukhuleni kweenkozo kunye nokwahlulwa kwesigaba, ukunciphisa amandla kunye nokuqina kwemathiriyeli.

Unyango lokuguga:

Emva konyango lwesisombululo, i-Hastelloy C ishushu kwiqondo lokushisa elifanelekileyo kwaye igcinwe ixesha elithile.

Emva koko yiyeke iphole kakuhle.

Le nkqubo inokuthi ilungelelanise ngakumbi i-microstructure kunye neempawu ze-alloy ukuphucula ukuxhathisa kunye namandla.

Unyango lwe-Anealing:

IHastelloy C ifudunyezwa kubushushu obufanelekileyo, ibanjwe kangangexesha elithile, ize ipholiswe kancinane.

Ukunyangwa kwe-Anealing kunokuphelisa uxinzelelo kunye nokuphucula amandla okuguqula izinto.
