I-254SMO yokwakheka kweekhemikhali zensimbi engenasici

254SMO umbhobho wentsimbi engatyiwa,1.4547 umbhobho wentsimbi,S31254 umbhobho wentsimbi,F44 umbhobho wentsimbi

Inkcazo:

254SMO yintsimbi ye austenitic stainless.Ngenxa yesiqulatho sayo semolybdenum ephezulu, inokumelana kakhulu nokubona umhlwa kunye nokubola kwemingxuma.I-254SMO yentsimbi engatyiwayo yaphuhliswa yaze yaphuhliswa ukuba isetyenziswe kwi-halide equlethe imo engqongileyo efana namanzi olwandle.I-254SMO ikwanayo nokumelana ne-corrosion efanayo, ngakumbi kwi-halide equlethe i-asidi, engaphezulu kunentsimbi yesiqhelo engenasici.I-C yayo iqulethe <0.03%, ngoko ibizwa ngokuba yintsimbi ecocekileyo ye-austenitic.I-Super stainless steel luhlobo lwentsimbi ekhethekileyo engenasici, okokuqala ekubunjweni kweekhemikhali yahlukile kwintsimbi eqhelekileyo engenasici, yintsimbi ephezulu ye-alloy ene-nickel ephezulu, i-chromium ephezulu, i-molybdenum ephezulu.Phakathi kwazo, i-254SMo equkethe i-6% Mo inokumelana nokugqwesa kwendawo, ukuchasana kakuhle kwe-pitting (PI≥40) kunye nokuxhatshazwa kwe-corrosion yoxinzelelo phantsi kweemeko zamanzi olwandle, i-aeration, i-gap kunye ne-low speed scour.Yimathiriyeli ethatha indawo ye-Ni-based alloy kunye ne-titanium alloy.Okwesibini, ekusebenzeni kobushushu obuphezulu okanye ukumelana nokugqwala, kunye nobushushu obuphezulu obuphezulu okanye ukuchasana nokugqwala, akuthatyathelwa indawo yintsimbi engama-304.Ukongezelela, ukusuka kulwahlulo lwensimbi engenasici, i-metallographic ekhethekileyo yensimbi yensimbi yisakhiwo esizinzileyo se-austenitic metallographic.
Ngenxa yokuba le ntsimbi ikhethekileyo luhlobo lwemathiriyeli ye-alloy ephezulu, ngoko ke kwinkqubo yokuvelisa inzima kakhulu, ngokuqhelekileyo abantu banokuthembela kuphela kwinkqubo yendabuko yokwenza le ntsimbi ikhethekileyo, enjenge-perfusion, i-forging, i-calendering njalo njalo.
 Imigangatho yesizwe:I-UNS S31254, DIN/EN 1.4547, ASTM A280, ASME SA-280
Ukuxhasa izixhobo ze-welding:I-ErNICRMO-3 ucingo, i-EnICRmo-3 electrode

Ukwenziwa kweekhemikhali:

Ukumelana nobushushu obuphezulu

1. Uvavanyo olubanzi lwentsimi kunye namava abanzi abonise ukuba nakwiqondo lokushisa eliphezulu, i-254SMO inokumelana okuphezulu kakhulu kwi-crevice-corrosion emanzini olwandle, apho kukho iintlobo ezimbalwa zensimbi engenasici.

2. I-254SMO's corrosion resistance in acidic and oxidizing halide solutions ezifana nezo zifunekayo kwimveliso ye-bleaching yephepha ithelekiseka neyona nto ixhaphakileyo ye-nickel-base kunye ne-titanium alloys.

3. Ngenxa yesiqulatho sayo se-nitrogen ephezulu, i-254SMO inamandla omatshini aphezulu kunezinye iintlobo ze-austenitic stainless steel.Ukongeza, i-254SMO ine-ductility ephezulu kunye namandla eempembelelo kunye nokuwelda okulungileyo.

4. Umxholo ophezulu we-molybdenum we-254SMO wenza ukuba ube nesantya esiphezulu se-oxidation kwi-annealing, okubangelwa indawo enqabileyo kunentsimbi eqhelekileyo emva kokukhetha.Kodwa oku akunayo impembelelo embi kwi-corrosion resistance yentsimbi.

Isicelo:
1. Ulwandle: Ulwakhiwo lwaselwandle kwimekobume yaseLwandle, ukukhutshwa kwetyuwa emanzini olwandle, urhwebo lwaselwandle, ukutshintshiselana ngobushushu bamanzi olwandle, njengemibhobho yokujiya enodonga olucekethekileyo epholiswe ngamanzi olwandle kumaziko ombane, izixhobo zokukhupha ityuwa, nakwizixhobo apho amanzi olwandle esenokungaphumi, njl.
2. Intsimi yokukhusela indalo: i-thermal power generation flue gas desulfurization device, unyango lwamanzi amdaka, iindawo eziphambili zezi: umzimba we-absorber tower, i-flue, iipaneli zomnyango, iindawo zangaphakathi, inkqubo yokutshiza, njl.
3. Amandla: ukuveliswa kwamandla eathom, ukusetyenziswa ngokupheleleyo kwamalahle, ukuveliswa kwamandla olwandle, njl.
4. Ishishini le-petrochemical: ukucocwa kwe-oyile, izixhobo zekhemikhali, izixhobo ze-petrochemical, ezifana ne-bellows kwi-petrochemical equipment, njl.
5. Intsimi yokutya: ukwenza ityuwa, imboni yokukhupha ityuwa, njengokwenza ityuwa okanye izixhobo zokukhupha ityuwa, ukwenza i-soy sauce, njl.
6. Imekobume ye-ion ye-chloride yoxinaniso oluphezulu: ishishini lokwenza iphepha, i-pulp kunye nezixhobo zokucoca iphepha, ezifana ne-pulp digester, izixhobo zokucoca, imigqomo yokuhluza kunye ne-press rollers kunye nezinye izixhobo zokuxubha.
