Amazwe ivalve yensimbi engenastainless steel stainless steel number ukuphunyezwa komgangatho wokulawula ivalve yentsimbi eziphambili izingxenye zetheyibhile 321 ivalve yentsimbi engenastainless elingana neyasekhaya 1Cr17Ni9Ti, 321 ukusebenza kwevalvu yensimbi engenasici kufana kakhulu ne304, kodwa ngenxa yokongezwa kwetitanium yesinyithi, ukuze ibe nokumelana okungcono. ukuya kumda wokutya kunye namandla obushushu obuphezulu. Ngenxa yokongezwa kwesinyithi se-titanium, ilawula ngokufanelekileyo ukubunjwa kwe-chromium carbide. I-valve ye-321 yensimbi engenasici inomsebenzi ongcono we-Stress Rapture kunye nobushushu obuphezulu be-Creep Resistance kuzo zombini iipropathi zoxinzelelo kunye nempahla ye-mechanical kune-valve ye-304 yensimbi engenasici. I-321 iivalvu zensimbi engenastainless zisetyenziselwa ukuxhathisa okuphezulu kumda wokudla okuziinkozo, ivalve yentsimbi engenastainless eyona njongo iphambili yokusebenza 304 ivelufa yensimbi engenastainless GB 0Cr18Ni9, GB 0Cr18Ni9 njengenjongo yevalve yentsimbi engenasici, inokumelana nokuhlwa okuhle, ukumelana nobushushu, amandla asezantsi obushushu kunye neempawu zoomatshini. ; Ukunyathela, ukugoba kunye nokunye ukusetyenzwa okushushu, akukho nto yonyango lobushushu eyenza lukhuni (akukho magnetic, usebenzisa ubushushu -196℃~800℃). Ivalve ye-321 yentsimbi engenastainless elingana ne-1Cr17Ni9Ti yasekhaya, i-321 yokusebenza kwevalvu yensimbi engenasici ifana kakhulu ne-304, kodwa ngenxa yokongezwa kwetsimbi ye-titanium, ukuze ibe nokuchasana ngcono kwi-corrosion yomda wengqolowa kunye namandla aphezulu obushushu. Ngenxa yokongezwa kwesinyithi se-titanium, ilawula ngokufanelekileyo ukubunjwa kwe-chromium carbide. I-valve ye-321 yensimbi engenasici inomsebenzi ongcono we-Stress Rapture kunye nobushushu obuphezulu be-Creep Resistance kuzo zombini iipropathi zoxinzelelo kunye nempahla ye-mechanical kune-valve ye-304 yensimbi engenasici. I-321 ivalve yentsimbi engenastainless isetyenziswa kumda wenkozo ophezulu onganyangekiyo kwi-corrosion yekhemikhali, amalahle, ishishini lepetroleum kwibala lombhobho okwaziyo ukumelana nobushushu kunye nonyango lobushushu ngumbhobho onzima. I-valve ye-316 yensimbi engenasici ye-GB 0Cr17Ni12Mo2 0Cr17Ni12Mo2, ngenxa yokongezwa kwe-Mo, ngoko ke ukuxhathisa kwe-corrosion, ukumelana ne-atmospheric corrosion kunye namandla okushisa aphezulu kulungile, kunokusetyenziswa phantsi kweemeko ezinzima; I-316 iivalvu zensimbi ezingenasici ezisetyenziselwa: amanzi olwandle, imichiza, idayi, iphepha, i-oxalic acid, isichumisi kunye nezinye izixhobo zokuvelisa; I-316L i-valve yensimbi engenasici ye-GB 00Cr17Ni14Mo2 00Cr17Ni14Mo2, njenge-316L ivalve yensimbi engenasici ngaphezu kwe-316 i-valve yensimbi engenasici ineempawu ezifanayo, ukuxhathisa kwe-corrosion yomda weenkozo kungcono kune-316; Ukongeza, ukongezwa kwento ye-molybdenum kunokuphucula kakhulu ukuchasana kwayo ne-intergranular corrosion kunye ne-oxide yoxinzelelo lwe-oxide, kunye nokunciphisa ukuthambekela kokuqhekeka okushushu ngexesha le-welding. I-valve ye-316L yensimbi engenasici isetyenziselwa: isetyenziswa rhoqo kumanzi acocekileyo, amanzi adibeneyo, iyeza, i-sauce, iviniga kunye nezinye iimfuno zempilo, ukusebenza kwe-corrosion ephakathi ngamaxesha anamandla, i-valve ye-316 ye-stainless steel stainless isetyenziswe ngokukhethekileyo kwi-corrosion yomda weenkozo ineemfuno ezizodwa zeemveliso. I-valve yensimbi engenasici ye-310S yindlela eqhelekileyo ye-valve yensimbi engenasici e-United States, ileyibhile yasekhaya yi-(2520) 0Cr25Ni20, luhlobo lwe-valve yensimbi engenasici, i-S kwi-310S ibhekisela kusetyenziso olukhethekileyo lwe-valve yensimbi engenasici. Iimpawu ze-0Cr25Ni20 (310S) -- ukumelana nobushushu obuphezulu be-oxidation, amandla aphezulu obushushu. Sebenzisa - umbhobho wokukhupha i-Bellows, i-microwave oven Heater, iTube, i-bladder ephezulu yokushisa, isithando somlilo kunye nezinye iimfuno zokuxhathisa ubushushu beevalvu zensimbi engenasici. Ngokuqhelekileyo ** kaninzi ukubona i-304, i-316 ivalve yensimbi engenasici injalo, i-304 icandelo eliqhelekileyo yi-18% ye-chromium kunye ne-8% ye-nickel, eyaziwa ngokuba yi-valve ye-18-8 yensimbi engenasici. Iimpawu zolu hlobo lwevalve yensimbi engenasici azinamagnetic, azinakutshintshwa yindlela yonyango yobushushu yesakhiwo semetallografi, ukusetyenzwa kakuhle, kwaye ngenxa ye-alloy element - nickel, ke ukuxhathisa umhlwa kungcono kunokuqulatha ichromium kuphela (akukho nickel) kwezinye iindidi ezimbini zeevalvu zentsimbi engatyiwayo. Ukusetyenziswa okuphambili kwee-300 ze-valve zensimbi ezingenasici: zisetyenziswa ngokubanzi kwi-petroleum, ikhemikhali, i-pharmaceutical, isichumisi sekhemikhali, amandla ombane kunye namanye amashishini eemeko ezahlukeneyo zokusebenza kumbhobho. Kwiingqondo zabantu abaqhelekileyo, into ebizwa ngokuba yi-valve yensimbi engenasici ibhekisela kwii-valve zensimbi ezingenasici ze-300 (ingakumbi i-304 yensimbi engenasici).
