Kuyisinqumo esihle kakhulu sokufaka izicelo ezimbonini ze-petrochemical, amakhemikhali, nezokuphatha ukushisa, kanye nezingxenye zesithando somlilo nezinye izinhlelo zokusebenza ezishisa kakhulu. Ipuleti lensimbi engagqwali elingu-310S liyisicaba, ishidi elincanyana elenziwe ngale ngxubevange ethile.
3.253MA (S30815) ipuleti lensimbi engagqwali
Izici: I-253MA iyinsimbi engagqwali ye-Austenitic ekwazi ukumelana nokushisa edizayinelwe izinhlelo zokusebenza ezidinga amandla aphezulu okukhasa kanye nokumelana nokugqwala okuhle. Izinga lokushisa layo lokusebenza liyi-850-1100 ℃.
I-253MA iwuhlobo oluthile lwengxube yensimbi engagqwali eyenzelwe ukusetshenziswa okunokushisa okuphezulu. Inikeza ukumelana okuhle kakhulu ne-oxidation, i-sulfidation, kanye ne-carburization emazingeni okushisa aphakeme. Lokhu kuyenza ifanelekele ukusetshenziswa ezimbonini ezihlukahlukene, kuhlanganise nalezo ezibandakanya ukushisa nokugqwala, njengengxenye ye-petrochemical, ukukhiqiza ugesi, kanye neziko leziko lezimboni.Amashidi angu-253MA ayizingcezu ezincane, eziyisicaba zezinto ezenziwe ngale alloy. Zisetshenziswa ezinhlelweni ezahlukahlukene lapho inhlanganisela yokumelana nokushisa okuphezulu nokumelana nokugqwala kubalulekile. Amashidi angasikwa futhi abunjwe abe yizimo ezahlukene ukuze ahlangabezane nezidingo ezithile zephrojekthi.
Amashidi angu-253MA, Ukwakheka Kwamakhemikhali Amacwecwe

Ukumelana ne-253MA Plate Corrosion kanye nemvelo yokusetshenziswa okuyinhloko:
I-1.I-Corrosion Resistance: I-253MA inokumelana ne-oxidation enhle kakhulu, ukumelana nokugqwala kwezinga eliphezulu lokushisa, kanye namandla amangalisayo emishini yezinga eliphezulu lokushisa. Isebenza kakhulu phakathi kwezinga lokushisa elingu-850 kuya ku-1100°C.
2.Izinga Lokushisa: Ukuze usebenze kahle, i-253MA ifaneleka kangcono ukusetshenziswa ngaphakathi kwebanga lokushisa elingu-850 kuya ku-1100°C. Emazingeni okushisa aphakathi kuka-600 no-850°C, izinguquko zesakhiwo zenzeka, okuholela ekunciphiseni kokuqina komthelela ekamelweni lokushisa.
3.Amandla Emishini: Le alloy idlula izinsimbi ezivamile ezingenasici, ezifana no-304 no-310S, ngokwamandla esikhashana esifushane emazingeni okushisa ahlukahlukene ngaphezu kuka-20%.
4.Ukwakheka Kwekhemikhali: I-253MA ifaka ukwakheka kwamakhemikhali okunokulinganisela okukunikeza ukusebenza okukhethekile ebangeni lokushisa elingu-850-1100°C. Ikhombisa ukumelana ne-oxidation ephezulu kakhulu, imelana nezinga lokushisa elifinyelela ku-1150°C. Iphinde inikeze ukumelana okuphezulu kwe-creep namandla e-creep fracture.
I-5.I-Corrosion Resistance: Ngokungeziwe emandleni ayo ezinga lokushisa eliphezulu, i-253MA ibonisa ukumelana okuhle kakhulu nokugqwala kwezinga lokushisa eliphezulu kanye nokugqwala kwebhulashi ezindaweni eziningi ezinegesi.
6.Amandla: Inamandla okukhiqiza okuphezulu namandla aqinile emazingeni okushisa aphakeme.
7.Ukuhleleka kanye nokushisela: I-253MA yaziwa ngokuhleleka kwayo okuhle, ukushisela, kanye nokusebenza kanzima.
