Yaphuhliswa ngenxa yokuphucula ukumelana nokunganyangeki kwamaqondo aphezulu kumaqondo obushushu ngaphezulu kwe-1000¡f (537¡ãc).
347 Ukuxhathisa ngokugcobayo kumbhobho we-nerrasion ye-pipe kunye nemizobo yepop
I-316l, nangona kunjalo, lukhetho olungcono kwiprojekthi efuna i-welding eninzi kuba i-316 ithethwe ngakumbi ukubohloka kwe-WOLL DEST kune-316L kwi-WODL.
I-Alloy 347h (ayingaphezulu kwe-S3409) ipleyiti yentsimbi engenasitali yikharbon ephezulu (i-0,04 ¨c 0,10) inguqulelo ye-alloy.

I-Chromium, iMolybdenum, iNickel kunye ne-nitrogen zonke zinegalelo ekuchanyoneni ngokubanzi ekususweni kwemithombo yeendaba ezahlukeneyo
Owona manqanaba mabini axhaphakileyo angama-304 nowama-316. Umahluko ophambili kukudibanisa i-molybdenum, isabelo esiphucula kakhulu ukunganyangeki kwetyiwa, ngakumbi ekubonakaliseni ityiwa.
I-al6xn yangaphambili yokunyangwa kwenkqubo yokunganyangeki kwi-CROSION CROSIONS
Ngaba umxholo wekharbon ophantsi we-Alloy uyawenza ukuba ihlawulwe ngaphandle kwe-inllosion ye-intergranium ebangelwa kukubekwa kwe-chromium ye-chromium ye-chromium ye-chromium ye-chromium eyenza ukuba isetyenziswe kwimeko yendalo.
Iipleyiti zentsimbi ye-alloy kunye neekhiliki
Intsimbi engama-304 ingenalo ingenayo ubuthathaka obuthile: Ithathwa kukungabikho kwesisombululo se-chloride okanye imeko ye-saline efana nonxweme.
Inokuchasana ngokugqwesileyo kwi-insosion engaphakathi emva kokuba ibonakalise amaqondo obushushu kwi-chromium ye-chromium ye-chromium ye-chromium ye-chromium ye-800 ¨C 1500 NORTNF (427 ¨c 816¡c).?
Inkonzo efuna ipropathi efanelekileyo ye-ripture kunye ne-ropture, i-Intloy 800h okanye i-800 ht isetyenzisiwe. Iziqulatho eziphezulu zeNickel kunye neChromium kuma-Aflines zinika ukunganyangeki kolusu.
Intsimbi engama-304 yeyona ndlela ixhaphakileyo yentsimbi engenasimo ehlabathini ngenxa yokunganyangeki kunye nexabiso. Ine-16% ukuya kwi-24% chromium ukuya kuthi ga kwi-35% i-nickel, kunye nexabiso elincinci lekhabhoni neManganese.
I-316l ikwayintsimbi enkulu engaqhelekanga yobushushu obuphezulu, ukusetyenziswa okuphezulu kwe-corrosion, yiyo loo nto ithandwa kakhulu ngokusetyenziswa kwiiprojekthi zokwakha nezaselwandle.
I-904l Ibanga elingafaniyo alifani nelinye intsimbi. Ngenxa yezixa zayo ezongezelelweyo zeChromium, iMolybdenum, i-nickel kunye nobhedu, i-904l yensimbi yokunganyangeki okuphezulu kwi-corrosion, i-rumps kunye ne-acids.
Umxholo weChromium oPhakamileyo ukhuthazo kwaye ugcine ifilimu ekhusela umbandela kwiindawo ezininzi zoncedo.
Xa ukhetha iziqu ezingenazimpawu ezimele ukunyamezela iindawo ezinomhlaba, ii-austitotic stails zihlala zisetyenziswa.
I-Chromium yi-arhente eyintloko yokufumana ukunganyangekala kwendawo ekungathathi hlangothi.
I-Alloty 904l isebenza ngaphandle kwezinye izifuba ezingenanto ezingenanto ngenxa yenqanaba eliphezulu lokulwa kwe-nickel kunye ne-molybdenum.
Intsimbi engama-316 ingenasinqwazi sinekhabhoni engaphezulu kwe-316l. Oku kulula ukukhumbula, njengoko i-L ime "iphantsi."
I-Alloty inolwazi oluhle lwe-oxidation kunye namandla e-cerp ukuya kwi-1500¡in (816¡cn). Ikwanolwazi lobushushu obuphantsi.
I-Alloy 347 ipleyiti yentsimbi engenanto ayinakukhubazeka ngonyango lobushushu, kuphela ngokusebenza kubandayo.
Intsimbi engenasitali 904l \ / 1.4539 Izixhobo ezinokusetyenziswa ukwenza iphepha elishushu neliqengqelekayo, iimveliso ezigqityiweyo, ezigqityiweyo, kunye nemibhobho ye-weldied yezicelo zoxinzelelo.
I-Alloy 347 (ayingase-S34700) yi-Columbium ichithe i-austenitic plates yensimbi kunye nokunganyangeki kweyona meko inamandla kwi-321 (i-S32100).
I-al6xn inamandla amakhulu obunye kunamabala aqhelekileyo aqhelekileyo, ngelixa ugcina ixesha eliphezulu kunye namandla empembelelo.
I-chromium, iMolybdenum kunye ne-nitrogen yandisa ukunganyangeki ekupheliseni ukungakhathali. I-nickel ibeka ubume be-austititic.
I-904l Austitic austenitic yentsimbi yentsimbi
Inani eliphezulu le-nickel kunye neChromium kwi-austentinitic stails ezingenazimpawu zinika iipropathi ezibalaseleyo, kunye nokunganyangeki kwengqondo.
Ukongezwa kobhedu kweli nqanaba kunika ukumelana nokunganyangeki ngakumbi kunezifundo eziqhelekileyo zeChromium-Nikel Stail, ngakumbi ngokuchasene ne-sulfuric, phosphoric kunye ne-acetic acids. Nangona kunjalo, ukusetyenziswa kwe-hydrochloric acid ilinganiselwe.
