Amashidi ensimbi engagqwali anobuso obubushelelezi, i-plasticity ephezulu, ukuqina, kanye namandla omshini, futhi amelana nokugqwala okuvela kumagesi ane-asidi ne-alkaline, izixazululo, kanye nezinye izinto ezisetshenziswayo. Kuyinsimbi ehlanganisiwe engagqwali kalula, kodwa ayimelani nokugqwala nhlobo. Amashidi ensimbi engagqwali abhekisela kumashidi ensimbi angamelani nokugqwala avela ezintweni ezibuthakathaka ezifana nomoya, umusi, namanzi, kuyilapho amashidi ensimbi angamelani ne-asidi abhekisela kumashidi ensimbi angamelani nokugqwala avela ezintweni ezisetshenziswayo ezisebenzisa amakhemikhali ...
Amashidi ensimbi engagqwali afika ngamamaki ahlukahlukene, kanye nochungechunge olubaluleke kakhulu kwezentengiselwano oluhlanganisa i-austenitic, i-ferritic, i-duplex, kanye ne-martensitic. Amamaki ngalinye anezakhiwo ezihlukile zemishini kanye nokumelana nokugqwala, okwenza afanelekele ukusetshenziswa okuthile.
Insimbi Engagqwali Yase-Austenitic (Uchungechunge lwama-300)
304/304L: Insimbi engagqwali esetshenziswa kabanzi. Inokumelana okuhle nokugqwala, ukwakheka kahle, kanye nokushiselwa.
316/316L: Ngokungezwa kwe-molybdenum engu-2-3%, inokumelana okuhle kakhulu nama-chloride (amanzi olwandle, usawoti wokususa i-icing).
321: Ngokufaka iziqinisi ze-titanium, kuvimbela ukuzwela ngesikhathi sokushisela.
310S: Izinga lokushisa eliphezulu (kufika ku-1100°C), lifanele izingxenye zesithando somlilo.
Insimbi Engagqwali ye-Ferritic (uchungechunge lwama-400, isib. 430, 409, 439) Amashidi ensimbi engagqwali ye-Ferritic aqukethe i-chromium engu-10.5%–27%, okuqukethwe kwekhabhoni okuphansi kakhulu (<0.1%), kanye ne-nickel encane kakhulu noma engekho nhlobo. Anamandla kazibuthe futhi anokumelana okuhle nokuqhekeka kokugqwala kokucindezeleka, kodwa ukwakheka kwawo nokuqina kwawo kungaphansi kwensimbi engagqwali ye-austenitic. Awanakuqiniswa ngokwelashwa kokushisa. Izicelo ezijwayelekile: izinhlelo zokukhipha umoya zezimoto, amaphaneli okwakha, kanye nezinto zikagesi zangaphakathi. Ezindaweni ezithambile, ibanga lama-430 liyindlela ejwayelekile engabizi kakhulu kunebanga lama-304.
Insimbi Engagqwali Ephindwe Kabili (isb., 2205, 2507) Insimbi engagqwali Ephindwe Kabili inesakhiwo esincane esakhiwe yingxube yezinto ze-austenitic neze-ferritic (cishe 50/50). Ngenxa yokuqukethwe kwayo okuphezulu kwe-chromium (21-26%), okuqukethwe kwe-nickel okumaphakathi (4-7%), kanye nokuqukethwe kwe-molybdenum (0-4%), insimbi engagqwali engu-2205 inamandla okukhiqiza cishe kabili kunensimbi engagqwali ye-austenitic, kuyilapho igcina ukumelana okuhle kakhulu nokuqhekeka kokugqwala kwe-chloride stress. Insimbi engagqwali engu-2205 isetshenziswa kabanzi emathangini amakhemikhali, ekususeni usawoti emanzini olwandle, kanye nasezigayweni ze-pulp. Amandla ayo aphezulu avumela ukusetshenziswa kwamashidi amancane, ngaleyo ndlela kunciphisa isisindo kanye nezindleko.
Insimbi engagqwali ye-Martensitic (isb., 410, 420) iqukethe i-chromium engu-11-17% kanye nokuqukethwe kwekhabhoni okuphezulu (0.1-1.2%), ngaleyo ndlela ivumela ukuqina ngokwelashwa kokushisa. Zinamandla, ziqinile, futhi azigugi, kodwa ukumelana kwazo nokugqwala kuphansi kunokwensimbi engagqwali ye-austenitic noma ye-duplex.
Umehluko omkhulu phakathi kwamapuleti ensimbi engagqwali angu-304 no-316: insimbi engagqwali engu-304, esihlangana nayo nsuku zonke, iwuphawu lwensimbi engagqwali yezinga lokudla kanye nenkosi yokusebenza kahle kwezindleko ekusetshenzisweni kwasekhaya. Iqhosha ngokumelana nokugqwala okuhle kakhulu, ukuvimbela ukugqwala, kanye nokumelana nokushisa okuphezulu. Ngezinkomishi ezivalekile, izitsha zokudla, izinki zasekhishini, imishini yokucubungula ukudla, kanye nehadiwe yokugezela, i-304 iyisinqumo esifanele. Iphephile, ayinabo ubuthi, futhi ayigqwali ukusetshenziswa kwansuku zonke, ifaneleka ezimweni eziningi zasekhaya, futhi inikeza ukuqina okumangalisayo.
Ngakolunye uhlangothi, insimbi engagqwali engu-316 iyinto yezinga lezokwelapha/eliphezulu ezimbonini. Inezela i-molybdenum ku-304, ithuthukisa kakhulu ukumelana kwayo nokugqwala, ukumelana ne-asidi ne-alkali, futhi iyenze imelane kakhulu namazinga okushisa aphezulu kanye nokugqwala kwamanzi olwandle. Isetshenziswa kabanzi ezitsheni zasekhishini ezisezingeni eliphezulu, kumadivayisi ezokwelapha, kumapayipi amakhemikhali, nasezindaweni zangaphandle ezisogwini. Nakuba ingabalulekile ekusetshenzisweni kwansuku zonke kwasekhaya, i-316 iyisisombululo esifanele sezinhlelo zokusebenza ezidinga ukumelana nokugqwala okuphezulu.
Omunye umehluko obalulekile usezindleleni ezibizayo; ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel ne-molybdenum, insimbi engagqwali engu-316 ivame ukubiza kakhulu kunensimbi engagqwali engu-304. Ngakho-ke, ukukhetha phakathi kwalezi zinsimbi ezimbili kuvame ukuncika ezidingweni ezithile zokusetshenziswa, kufaka phakathi imikhawulo yesabelomali kanye nezici zemvelo.
Insimbi engagqwali iyinto yobunjiniyela eguquguqukayo kakhulu, ikakhulukazi amagreyidi angu-304 no-316, adlala indima ebalulekile ezimbonini ezahlukahlukene ngenxa yezakhiwo zawo ezihlukile kanye nezicelo. Kungakhathaliseki ukuthi kusezimbonini zokucubungula ukudla, zokwakha, zezimoto, zezokwelapha, zamakhemikhali, noma zamandla, amashidi ensimbi engagqwali abelokhu eyisinqumo esithembekile konjiniyela nabakhiqizi. Njengoba izimboni ziqhubeka nokukhula futhi isidingo sezinto ezihlala isikhathi eside, ezingagqwali siqhubeka nokukhula, ukubaluleka kwamashidi ensimbi engagqwali kuzokhula kuphela.
Uma udinga ukuthenga imikhiqizo yeshidi lensimbi engagqwali, sicela uchofoze ukuze usithinte ukuze uthole ukubonisana. I-Jindalai Steel Group Co., Ltd. izokunikeza izimpendulo zobungcweti kakhulu.
