I-201 insimbi engenasici yintsimbi engama-200 ye-austenitic stainless steel ephuhliswe ngokutshintsha i-manganese, i-nitrogen kunye nezinye izinto nge-nickel. Inokumelana ne-corrosion elungileyo kunye nemisebenzi eshushu kunye nebandayo, eyaneleyo yokutshintsha indawo yangaphakathi, izixeko ezingaphakathi kunye nokusetyenziswa kwangaphandle. Iimveliso ze-304 zensimbi ezingenasici ezisetyenziswa kwiindawo ezinobungozi obuphantsi.
Ngenxa yokuba ixabiso le-nickel liqhubeka liguquguquka, abaninzi abavelisi bafuna ezinye iimveliso ze-austenitic stainless steel kunye nemisebenzi efana ne-304 yensimbi engenasici. Ekuqaleni koo-1930, intsimbi yokuqala ye-chromium-manganese austenitic yentsimbi yaveliswa, kwaye imanganese kwintsimbi yathatha indawo yenickel. Emva koko, uphando olongezelelweyo luqhutywe kwisabelo esicacileyo sokwakheka, i-nitrogen kunye nobhedu zisetyenzisiwe, kunye nezinto ezifana nekhabhoni kunye nesulfure, ezichaphazela kakhulu umsebenzi wedatha, njl., ekugqibeleni zenze uluhlu lwe-200 lufumaneke.
Okwangoku, iindidi eziphambili ze-200 ze-stainless steel series ziyi: J1, J3, J4, 201, 202. Kwakhona kukho amabakala ensimbi angama-200 anolawulo oluphantsi lwe-nickel content. Ngokubhekiselele kwi-201C, yinqanaba le-201 yensimbi engenasici ephuhliswe yiplanti yensimbi enye e-China kwixesha elizayo. Uphawu lokuthengisa olusemgangathweni lukazwelonke lwe-201 lu: 1Cr17Mn6Ni5N. I-201C iyaqhubeka ngesiseko se-201 Nciphisa umxholo we-nickel kwaye wongeze umxholo we-manganese.
201 ukusetyenziswa kwentsimbi engatyiwayo
Ngenxa yokuba i-201 insimbi engenasici ineempawu zokumelana ne-asidi, ukuxhathisa kwe-alkali, ukuxinana okuphezulu, ukugulisa ngaphandle kwamaqamza, kwaye akukho mibhobho, ilungele kakhulu ukuvelisa iimeko ezahlukeneyo kunye nezigqubuthelo ezisezantsi, kwaye ezinye ezininzi zisetyenziselwa ukuhombisa imibhobho, Ezinye zitsalwe ngokunzulu. iimveliso zemibhobho yoshishino.
I-201 yensimbi engenasici yeekhemikhali
Izinto ze-201 zentsimbi yentsimbi zine-manganese kunye ne-nitrogen endaweni yezinye okanye zonke izinto ze-nickel. Ngenxa yokuba inokuvelisa umxholo we-nickel ophantsi kunye ne-ferrite ayilungelelananga, umxholo we-ferrochrome kwi-200 series stainless steel iyancipha ukuya kwi-15% -16%, Ezinye iimeko ziye zehla ukuya kwi-13% -14%, ngoko ukuxhathisa kwe-corrosion ye-200 series stainless. intsimbi ayinakuthelekiswa ne-304 okanye ezinye iintsimbi ezingenasici ezifanayo. Ukongezelela, phantsi kweemeko ze-acidic eziqhelekileyo kwiindawo ezigqwethiweyo zendawo yokuqokelela kunye ne-gap, umphumo we-manganese kunye nobhedu uya kuncitshiswa kwaye umphumo wokubuyisela kwakhona phantsi kweemeko ezithile. Izinga lomonakalo we-chromium-manganese insimbi engenasici phantsi kwezi meko malunga ne-10-100 ngamaxesha angama-304 ensimbi engenasici. Kwaye ngenxa yokuba kwimveliso yokusebenza kaninzi ayikwazi ukulawula ngokuchanekileyo umxholo wesulfure kunye nekhabhoni eseleyo kwezi zintsimbi, idatha ayinakulandelwa kwaye ilandelwe, nangona xa idatha ifunyenwe. Ke ukuba akuchazwanga ukuba ziziintsimbi ze-chromium-manganese, ziya kuba ngumxube oyingozi kakhulu wentsimbi yentsimbi, oya kubangela ukuba ukuphosa kuqulathe umxholo wemanganese ngokungalindelekanga. Ngoko ke, ezi zinsimbi ezingenasici kunye ne-300 series stainless steels akufanele zitshintshwe okanye zitshintshwe. Ezi zimbini ziphelele kwinqanaba elifanayo malunga nokumelana nokubola.
