Amazwe i-valve yensimbi engagqwali yensimbi ukuqaliswa kwenombolo yokulawula okujwayelekile kwe-valve yensimbi izingxenye eziyinhloko ithebula 321 i-valve yensimbi engagqwali elilingana ne-1Cr17Ni9Ti yasekhaya, ukusebenza kwe-valve yensimbi engagqwali321 kufana kakhulu no-304, kodwa ngenxa yokwengezwa kwensimbi ye-titanium, ukuze ibe nokumelana okungcono. ukugqwala komngcele wokusanhlamvu namandla okushisa aphezulu. Ngenxa yokwengezwa kwensimbi ye-titanium, ilawula ngempumelelo ukwakheka kwe-chromium carbide. Ivalvu yensimbi engagqwali engu-321 inokusebenza okungcono kwe-Stress Rupture kanye nezinga lokushisa eliphakeme le-Creep Resistance kukho kokubili ukucindezeleka nezakhiwo zemishini kune-valve yensimbi engagqwali engu-304. 321 Amavalvu ensimbi engagqwali asetshenziselwa ukumelana okuphezulu nokugqwala komngcele wokusanhlamvu valavu yensimbi engenasici izinjongo zokusebenza eziyinhloko 304 valvu yensimbi engagqwali GB 0Cr18Ni9, GB 0Cr18Ni9 njengenhloso ye-valve yensimbi engagqwali, inokumelana nokugqwala okuhle, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini. ; Ukunyathela, ukugoba nokunye ukucubungula okushisayo kuhle, akukho mkhuba oqinisayo wokwelapha ukushisa (akukho kazibuthe, kusetshenziswa izinga lokushisa -196℃~800℃). Ivalvu yensimbi engagqwali engu-321 elingana ne-1Cr17Ni9Ti yasekhaya, ukusebenza kwevalvu yensimbi engagqwali321 kufana kakhulu no-304, kodwa ngenxa yokwengezwa kwensimbi ye-titanium, ukuze imelane kangcono nokugqwala komngcele wokusanhlamvu namandla okushisa aphezulu. Ngenxa yokwengezwa kwensimbi ye-titanium, ilawula ngempumelelo ukwakheka kwe-chromium carbide. Ivalvu yensimbi engagqwali engu-321 inokusebenza okungcono kwe-Stress Rupture kanye nezinga lokushisa eliphakeme le-Creep Resistance kukho kokubili ukucindezeleka nezakhiwo zemishini kune-valve yensimbi engagqwali engu-304. 321 Ivalvu yensimbi engagqwali isetshenziswa emngceleni wokusanhlamvu ukumelana nokugqwala kwamakhemikhali, amalahle, imboni ye-petroleum emkhakheni wepayipi elikwazi ukumelana nokushisa futhi ukwelashwa kokushisa kuyipayipi elinzima. I-valve yensimbi engagqwali engu-316 GB 0Cr17Ni12Mo2 0Cr17Ni12Mo2, ngenxa yokwengezwa kwe-Mo, ngakho ukumelana kwayo nokugqwala, ukumelana nokugqwala komkhathi namandla okushisa aphezulu kuhle kakhulu, kungasetshenziswa ngaphansi kwezimo ezinzima; 316 amavalvu ensimbi engagqwali asetshenziswa: emanzini olwandle, amakhemikhali, udayi, iphepha, i-oxalic acid, umanyolo nezinye izinto zokukhiqiza; I-valve yensimbi engenasici engu-316L GB 00Cr17Ni14Mo2 00Cr17Ni14Mo2, njenge-valve yensimbi engu-316L ngaphezu kwe-valve yensimbi engagqwali engu-316 inezici ezifanayo, ukumelana nokugqwala komngcele wokusanhlamvu kungcono kuno-316; Ngaphezu kwalokho, ukungezwa kwesici se-molybdenum kungathuthukisa kakhulu ukumelana kwayo nokugqwala kwe-intergranular kanye nokugqwala kokucindezeleka kwe-oxide, futhi kunciphise ukuthambekela kokuqhekeka okushisayo ngesikhathi sokushisela. 316L insimbi engagqwali valve isetshenziswa: ngokuvamile asetshenziswa emanzini ahlanzekile, amanzi distilled, umuthi, isoso, uviniga nezinye izidingo zezempilo, medium ukugqwala ukusebenza izikhathi ezinamandla, 316 insimbi engagqwali ukusetshenziswa okukhethekile ngokumelene nokugqwala okusanhlamvu umngcele kunezidingo ezikhethekile imikhiqizo. I-valve yensimbi engagqwali engu-310S iyindlela evamile ye-valve yensimbi engagqwali e-United States, ilebula yasekhaya ithi (2520) 0Cr25Ni20, iwuhlobo lwe-valve yensimbi engenasici, i-S in 310S ibhekisela ekusetshenzisweni okukhethekile kwe-valve yensimbi engagqwali. 0Cr25Ni20 (310S) izici -- ukumelana nokushisa okuphezulu kwe-oxidation, amandla okushisa aphezulu. Sebenzisa - ipayipi le-exhaust Bellows, I-heater kahhavini ye-microwave, i-Tube, isinye sesithando somlilo esishisayo, isithando somlilo kanye nezinye izidingo zokumelana nokushisa kwama-valve ensimbi engagqwali. Ngokuvamile ** kuvame ukubona 304, 316 valvu yensimbi engagqwali injalo, 304 ingxenye evamile 18% chromium kanye 8% nickel, ngokuvamile eyaziwa ngokuthi 18-8 insimbi engagqwali valve. Izici zalolu hlobo lwe-valve yensimbi engagqwali akuzona-magnetic, azikwazi ukuguqulwa ngendlela yokushisa ukushisa kwesakhiwo se-metalography, ukucutshungulwa okuhle, futhi ngenxa ye-alloy element - i-nickel, ngakho-ke ukumelana nokugqwala kungcono kunokuqukatha i-chromium kuphela (cha nickel) kwezinye izinhlobo ezimbili zamavalvu ensimbi engagqwali. Ukusetshenziswa okuyinhloko kwama-valve ensimbi engagqwali angu-300 yilezi: ngokuvamile asetshenziswa ku-petroleum, amakhemikhali, ekhemisi, kumanyolo wamakhemikhali, amandla kagesi nezinye izimboni zezimo ezihlukahlukene zokusebenza epayipini. Ezingqondweni zabantu abavamile, okuthiwa i-valve yensimbi engenasici ibhekisela kuma-valve ensimbi engagqwali angu-300 (ikakhulukazi ama-valve angu-304 ensimbi engagqwali).
