Uphononongo lwabathengi

Intsimbi engenasimo ikwangathathi hlangothi kunye ne-Intert, kwaye i-Orter ilongeyo iqinisekisa kuhlangatyezwane neemfuno zolwakhiwo oluzinzileyo. Ngaphaya koko, ayibophanga imingxunya enokuthi iguqule ubume bayo xa inxibelelana nezinto ezifana namanzi.

I-316l 1.4401 S31601 i-Stainess yentsimbi yindlela yokhetho lombhobho kunye nomoya oqinileyo oqhelekileyo oqhele ukusetyenziswa kwoluhlu olubanzi lwezicelo ezivela kwimizi-mveliso nezorhwebo. Le phuli ye-SS3603 yenziwe kumgangatho ophezulu we-316l yentsimbi enyaweni ngokuchasene ne-oxidation kunye ne-staining yendawo enobunzima okanye iZicelo eziPhakamileyo.

I-Intokel-chromium we-Alomium-chromium we-Allomium 625 (Ayisi-N06625 \ / w.nr.

I-Dotelloy C22, ekwabizwa ngokuba yi-Alloty C22, yi-Austeiting Ausketic-chromium-rungbdenum-tungsbdenum-tungsbdenum-tungsbdenum-tungsbden-tungsbden-tungsbden-tungsbden-tungsbden-tungsn-tungsblen-tungsbden-tungsn-tungsbden-tungsble-tungsbden-tungsten-tungsten-tungsten-tungsn-tungsn of kunye noxinzelelo. Ifumaneka ngohlobo lweepleyiti,

Ukudityaniswa kweChromium, iMolybdenum kunye ne-nitrogen inika ukuphakama kwe-2205 ukhuseleko oluhle kwi-chloride pide lokungaziphathi, eyenza ukuba ibe luncedo kwiindawo zaselwandle, ezo zivaliweyo, izicelo ezivaliweyo zelog.

I-UNOLL 625 COIC ibonakaliswa kukungaxhathisi ngokugqwesileyo kwi-oxidation, kwiqondo lokushisa eliphezulu kunye nokudinwa. I-ASTM B443 ipleyiti ye-N06625 isetyenziswe ngokubanzi kwi-Aerospace, ukuqhubekiswa kweekhemikhali kunye nemizi-mveliso yeoyile kunye negesi ngenxa yamandla ayo aphezulu, ukuqina kunye nokuqinana nakwimeko ezigqithisileyo.

Ihlazo elingaxutywanga liqulunqelwe ngeendlela ezintathu ezahlukeneyo nezizimeleyo nangona zidityanisiwe; Iflethi, iigesi, kunye nokutyibilika; ezihlanganisene kwenye impembelelo, efanelekileyo. Ulawulo olukhethekileyo luyafuneka ekukhetheni nasekusebenziseni zonke izinto ezikhoyo zokufumana udibaniso, oluqinileyo lokuqina.

I-Alloty 800 Intamo ye-Wool Shounges Sinodumo olunamandla sinemveliso yokuvelisa ukuqaqamba okusemgangathweni weentlobo ezahlukeneyo eziya kuhambelana neemfuno zabaxumi bethu. Senza i-flaves engathandekiyo engama-800 enokuthenjwa kwaye iphezulu kumgangatho. Sisebenzisa izixhobo zeprimiyamu kunye noomatshini abaphambili bokuvelisa i-ASTM B564 AN08800 I-Acloy 800 Fufxees.

I-Stainess yentsimbi i-347 iFlange ye-Scals i-347 yindlela yokudibanisa imibhobho, i-valves, iimpompo kunye nezinye izixhobo zokwenza inkqubo yokufaka. Ikwabonelela ngokufikelela ngokulula kokucoca, ukuhlola okanye ukuguqulwa. Iiflethi zihlala zidliwe okanye zikrexesiwe. Amalungu afakwe ngokuxhonywa ngokuhlamba kunye fives ezimbini nge-gasket phakathi kwabo ukuze banike itywina.

Kuyakwazi ukumelana nodidi olubanzi lweekhemikhali ze-oxiding kunye nokungabi nakuphathelele ukuchasana nokuchasana nokuhlaselwa kunye nokuhlaselwa kwe-ravice phambi kobukho be-chloride kunye nezinye iindlela zokuhamba.

Imibhobho yentsimbi engama-316 iye yaba zizixhobo ezinokubonakala kwicandelo lemizi-mveliso. Olu lwabiwo lwesinyithi kunye ne-chrome ibonwa ngokunyangeka kwayo phezulu ekucocekeni, kunye nokuqina kwayo. I-316 ityhubhu yentsimbi engenasitali inokuveliswa kuzo zombini iityhubhu ezingenamthungo kunye ne-weldied ukuhlangabezana neemfuno ezithile zabathengi.

I-C22 idla ngokubonelelwa kwimeko enomnxeba enesidingo se-45 ksi. Nangona kunjalo, i-C22 inokubanda isebenze kumanqanaba aphezulu amandla.

I-flange yi-rollge efihliweyo, imilebe okanye irayisi, nokuba ingaphandle okanye ingaphandle, isebenza ukonyusa amandla (njengeflethi ye-Iron okanye i-T-MAAM); Ukuncamathela ngokulula \ / ukudluliselwa kwendlela yoqhakamshelwano kunye nenye into (njenge-flange ekupheleni kombhobho, isilinda se-Steam, njl njl. okanye ukuzinzisa nokukhokela iintshukumo zoomatshini okanye iinxalenye zayo (njenge-flange yangaphakathi yemoto kaloliwe okanye ivili le-tram, eligcina amavili ukuba abaleke khona amavili). Ibinzana elithi "iFlanger" likwasetyenziselwa uhlobo lwesixhobo esisetyenziselwa ukwenza iiflene.

Ukuxinana kukaTitanium malunga ne-60% ye-Affel engenasitali kunye ne-neckel alloy, obu boyili bobunzima buyenza ukuba ifundwe kwizicelo ezizeleyo njengee-aerospace.

Ngokugqibeleleyo kwaye iphinde isebenze ngokutsha, intsimbi engenanto yinzuzo ye-° GET Ngapha koko, kwicandelo lezokwakha, inqanaba layo lokubuyisela kwimeko yesiqhelo lisondele kwi-100%.

I-ASTM A479 I-DUPENEX yentsimbi ye-1.4462 i-Subled i-SCC ixhathise i-SCC ebalaseleyo kwizicelo ezininzi ezifana neetanki zamanzi ashushu, iitanki zokuqhekeza, izityalo zokuchitha kunye nezityalo zokuchitha kunye nezityalo zokuchitha. Ke ngoko, i-ASTM A479 i-A479 ye-dupplex yentsimbi yentsimbi i-S31803 ye-S31803 i-lock ye-lock ibonisa ubume be-ferric kunye ne-austititic.

Ibonisa ukunganyangeki okuhle kunye nokucutha iindawo ezinqabileyo. Eli babele le ladala itayitile yesidima, ifilimu yokukhusela engaphumi, kodwa igcina ukunganyangeki okukhulu kwe-oxidation Ekunyangeni ekuhlaleni.

I-304 i-tyhel yentsimbi engenasitali e-Infolligy, intsimbi engenanto, ekwabizwa ngokuba yi-Itox yentsimbi okanye i-inox, i-chromium, kunye ne-chokeium yentsimbi, i-chokel ye-1,2% ye-Carbon (ngobunzima). Eyona nto iphawuleka kakhulu malunga nezitho ezingezizo zichasene nokungaxhathisi kwabo, nto leyo eyonyukayo ngomxholo weChromium. Ukongezwa kweMolybDenum kuphucula ukumelana nokunganyangeki ekunciphiseni i-acids kunye nokuthatyathwa kwesisombululo se-chloride. Ke ngoko, kukho amabakala amaninzi entsimbi engenasibala kunye neziqulatho zeChromium kunye neMolybdenum ukuze zilungele imeko ye-Alo Alloty kufuneka i-Alloty kufuneka ihlale inyanzelekile.
