Insimbi ye-carbon, eyaziwa nangokuthi i-carbon steel, ibhekisela ku-iron ne-carbon alloys equkethe ngaphansi kuka-2% we-carbon, i-carbon steel ngaphezu kwe-carbon ngokuvamile iqukethe inani elincane le-silicon, i-manganese, isulfure ne-phosphorus.
Insimbi engagqwali, eyaziwa nangokuthi insimbi engagqwali engamelana ne-asidi, isho ukumelana komoya, isitimu, amanzi nezinye imidiya egqwalayo ebuthakathaka nama-acids, ama-alkali, usawoti kanye nezinye insimbi egqwala amakhemikhali afaka insimbi. Empeleni, insimbi imelana nemithombo yezindaba ebolayo ebuthakathaka ngokuvamile ibizwa ngokuthi insimbi engagqwali, kanti insimbi imelana nokugqwala kwemithombo yamakhemikhali ibizwa ngokuthi insimbi engamelana ne-asidi.
(1) Ukumelana nokugqwala nokuhuzuka
Insimbi engagqwali iyingxubevange ekwazi ukumelana nokugqwala ngenxa yemithombo yezindaba egqwala engaqinile njengomoya, isitimu, amanzi kanye nemithombo yamakhemikhali enolaka njengama-asidi, ama-alkali nosawoti. Futhi lo msebenzi ubangelwa ikakhulukazi ukwengezwa kwesici esingenasici - i-chromium. Uma okuqukethwe kwe-chromium kungaphezu kuka-12%, ingaphezulu lensimbi engagqwali lizokwenza ungqimba lwefilimu ene-oxidized, eyaziwa ngokuthi ifilimu ye-passivation, nalolu ungqimba lwefilimu ene-oxidized ngeke kube lula ukuncibilika emithonjeni ethile yezindaba, idlala indima enhle yokuhlukaniswa, inokumelana nokugqwala okuqinile.
I-Carbon steel ibhekisela ku-iron-carbon alloy equkethe ngaphansi kuka-2.11% we-carbon, eyaziwa nangokuthi i-carbon steel, ukuqina kwayo kuphakeme kakhulu kunensimbi engagqwali, kodwa isisindo sikhulu, i-plasticity iphansi, kulula ukugqwala.
(2) izingoma ezihlukene
Insimbi engagqwali imfushane ngensimbi engagqwali emelana ne-asidi, imelana nomoya, isitimu, amanzi nezinye izinto zemidiya ezonakalisayo ezibuthakathaka noma ngensimbi engagqwali ibizwa ngokuthi insimbi engagqwali; futhi izomelana nemithombo yamakhemikhali egqwalayo (ama-acids, ama-alkali, usawoti kanye nokunye ukufakwa kwamakhemikhali) ukugqwala kwensimbi kubizwa ngensimbi engamelana ne-asidi.
I-Carbon steel iyingxube ye-iron-carbon alloy enekhabhoni ephakathi kuka-0.0218% kuya ku-2.11%. Ibizwa nangokuthi i-carbon steel. Futhi ngokuvamile iqukethe amanani amancane e-silicon, i-manganese, isulfure, ne-phosphorus.
(3) Izindleko
Okunye okucatshangelwayo okubalulekile umehluko wezindleko phakathi kwe-carbon steel nensimbi engagqwali. Nakuba izinsimbi ezihlukahlukene zinezindleko ezihlukene, insimbi engagqwali ngokuvamile ibiza kakhulu kune-carbon steel, ikakhulukazi ngenxa yokwengezwa kwezakhi ezihlukahlukene zengxubevange, njenge-chromium, i-nickel, ne-manganese, ensimbi engagqwali.
Uma kuqhathaniswa ne-carbon steel, insimbi engagqwali inenani elikhulu lamanye ama-alloys axutshwe futhi abiza kakhulu uma kuqhathaniswa ne-carbon steel. Ngakolunye uhlangothi, i-carbon steel ngokuyinhloko iqukethe izakhi ezishibhile zensimbi ne-carbon. Uma unesabelomali esiqinile sephrojekthi yakho, i-carbon steel ingase ibe inketho engcono kakhulu.
Iyiphi eqinile, insimbi noma i-carbon steel?
I-Carbon steel ivamise ukuba nzima ngoba iqukethe ikhabhoni eningi, nakuba okubi ukuthi ijwayele ukugqwala.
Yiqiniso ubulukhuni obuqondile buzoxhomeka ebangeni, futhi kufanele uqaphele ukuthi akusiyo ephakeme ubulukhuni obungcono, njengoba impahla eqinile isho ukuthi kulula ukuphuka, kanti ubulukhuni obuphansi bunamandla kakhulu futhi mancane amathuba okuphuka.
