Izinga lokushisa eliphakeme elikwazi ukumelana nokubandaipayipi lensimbi engenamthungongezinga lokushisa eliphakeme kakhulu
ukumelana ne-oxidation.Inamandla okushisa aphezulu, ukumelana ne-oxidation, i-carburization
ukumelana, ukumelana ne-asidi, ukumelana ne-alkali, amandla aqinile nokumelana nokugqoka.Okuqhubekayo
izinga lokushisa lokusetshenziswa ngu-1150 °C.Izinga lokushisa elivamile lokusebenza akufanele lidlule ama-degree angu-1050,
futhi izinga lokushisa eliphezulu akufanele lidlule ama-degree angu-1200.Okuphezulu okuqukethwe kwekhabhoni
ye-elementi yekhabhoni ethinta ukusebenza kwezinga lokushisa eliphezulu elimelana ne-stainless
ishubhu lensimbi, bukhuni ubulukhuni, kodwa kubi nakakhulu ukuqina kwayo nokuqina.

Isibabule siwukungcola okuyingozi ensimbi.Lapho insimbi enokuqukethwe okuphezulu kwesibabule ingaphansi kwengcindezi
ukucubungula ekushiseni okuphezulu, kulula ukuba brittle futhi ngokuvamile kubizwa ngokuthi i-hot brittleness.
I-Phosphorus inganciphisa kakhulu ipulasitiki nokuqina kwensimbi, ikakhulukazi uma iphansi
amazinga okushisa.Lesi simo sibizwa ngokuthi i-cold brittleness.Ngensimbi yekhwalithi ephezulu, isulfure kanye
i-phosphorus kufanele ilawulwe ngokuqinile.Nokho, komunye umbono, ukufakwa
i-sulphur ephakeme ne-phosphorus ensimbi ephansi ye-carbon ingenza ukusika kube lula ukuphuka, okungukuthi
kuzuzisa ukuthuthukisa machinability of steel.I-Manganese ingandisa amandla ensimbi,
inganciphisa futhi iqede imiphumela emibi yesibabule, futhi ingathuthukisa ukuqina kwe
insimbi.

Insimbi ephezulu ye-alloy (insimbi ephezulu ye-manganese) enokuqukethwe okuphezulu kwe-manganese inokumelana okuhle nokugqokwa
nezinye izinto ezibonakalayo.I-antibacterial kanye nokushisa okuphezulu ukumelana nensimbi engagqwali
imikhiqizo yamapayipi eye yavela eminyakeni yamuva yizithandwa ezintsha emndenini wensimbi engagqwali.
Baphathwa ngokukhethekile ngokungeza izakhi ezithile ze-antibacterial ezifana nethusi nesiliva
insimbi engagqwali.Lesi sakhiwo esihle kakhulu sokuzihlanza se-antibacterial sibonisa ukuthi ukusetshenziswa kwayo
ithemba libanzi kakhulu.

Ishubhu lensimbi engagqwali elikwazi ukumelana nokushisa okuphezulu linokumelana okuhle ne-oxidation ngezikhathi ezithile
sebenzisa ngaphansi kwama-degree angu-1600 nasekusetshenzisweni okuqhubekayo ngaphansi kwama-degree angu-1700. Ebangeni lika-800-1575
amadigri, kungcono ukungasebenzisi ngokuqhubekayo izinga lokushisa eliphezulu ukumelana nensimbi engagqwali
ipayipi, kodwa lapho izinga lokushisa eliphezulu ukumelana nepayipi lensimbi engagqwali lisetshenziswa ngokuqhubekayo ngaphandle
lolu hlu lokushisa, insimbi engagqwali inokumelana nokushisa okuhle.Izinga lokushisa eliphezulu
ipayipi lensimbi elikwazi ukumelana nokubanda linamandla okumelana nemvula ye-carbide kunensimbi engagqwali engu-316,
futhi izinga lokushisa elingenhla lingasetshenziswa.

Ishubhu lensimbi elidonsayo elikwazi ukumelana nokushisa okuphezulu eline-oxidation yokushisa ephezulu kakhulu
ukumelana.Inamandla okushisa aphezulu, ukumelana ne-oxidation, ukumelana ne-carburization, i-asidi
ukumelana, ukumelana ne-alkali, amandla aqinile nokumelana nokugqoka.Ukusetshenziswa okuqhubekayo
izinga lokushisa ngu-1150 °C.Izinga lokushisa elivamile lokusebenza akufanele lidlule ama-degree angu-1050, futhi
izinga lokushisa eliphezulu akufanele lidlule ama-degree angu-1200.
