Simbi inoiswa mugiredhi uye inoiswa mumapoka mana: Carbon steels, Alloy steels, Stainless simbi Chishandiso simbi
Type 1-Carbon steels
Kunze kwekabhoni nesimbi, kabhoni simbi dzine chete huwandu hwezvimwe zvikamu.Carbon steels ndiyo yakajairika pamagiredhi mana esimbi, inoverengera 90% yehuwandu hwekugadzirwa kwesimbi!Carbon simbi inoiswa muzvikamu zvitatu zvichienderana nehuwandu hwekabhoni musimbi:
l Yakaderera kabhoni simbi / zvinyoro simbi (kusvika 0.3% kabhoni)
l Masimbi epakati kabhoni (0.3–0.6% kabhoni)
l High carbon steels (inopfuura 0.6% kabhoni)
Makambani anowanzo gadzira simbi idzi muhuwandu hukuru sezvo isingadhure uye yakasimba zvekuti inogona kushandiswa mukuvaka kwakakura.
Type 2-Alloy steels
Alloy steels anogadzirwa nekubatanidza simbi nezvimwe zvekuwedzera alloying senge nickel, mhangura, chromium uye/kana aluminium.Kubatanidza zvinhu izvi kunovandudza simba, ductility, corrosion resistance uye machinability yesimbi.
Type 3-Stainless simbi
Stainless simbi mamakisi akasanganiswa ne10-20% chromium pamwe nickel, silicon, manganese, uye kabhoni.Nekuda kwekuwedzera kugona kwavo kurarama nemamiriro ekunze asina kunaka aya masimbi ane huturu hwekusaita ngura uye akachengeteka kushandisa mukuvaka kunze.Stainless simbi mamakisi anowanzoshandiswa mumidziyo yemagetsi.
Semuenzaniso, 304 simbi isina tsvina inotsvakwa zvakanyanya nekuda kwekugona kwayo kumira nharaunda ichichengetedza zvinhu zvemagetsi zvakachengeteka.
Nepo magiredhi akasiyana esimbi asina tsvina, anosanganisira 304 simbi isina tsvina, aine nzvimbo muzvivakwa, simbi isina tsvina inowanzotsvakwa nekuda kwehutsanana hwayo.Aya masimbi anowanikwa zvakanyanya mumidziyo yekurapa, mapaipi, midziyo yekumanikidza, kucheka zviridzwa uye michina yekugadzira chikafu.
Type 4-Tool steels
Masimbi emidziyo, sezita rinoratidza, anokunda mukucheka nekuchera michina.Kuvapo kwe tungsten, molybdenum, cobalt uye vanadium kunobatsira kuvandudza kupisa kwekupisa uye kusimba kwakawanda.Uye nekuti vanobata chimiro chavo kunyangwe pasi pekushandiswa zvakanyanya, iwo ndiwo akasarudzika zvinhu zvezvishandiso zvakawanda zvemaoko.
Simbi classifications
Kupfuura mapoka mana, simbi inogona zvakare kurongeka zvichienderana nemhando dzakasiyana dzinosanganisira:
Kuumbwa: carbon range, alloy, stainless, nezvimwewo.
Kupedzisa nzira: inopisa yakakungurutswa, inotonhora yakatenderedzwa, kutonhora kupera, nezvimwe.
Nzira yekugadzira: choto chemagetsi, chinoramba chichikandwa, nezvimwe.
Microstructure: ferritic, pearlitic, martensitic, nezvimwewo.
Simba remuviri: pa ASTM zviyero
De-oxidation process: kuurayiwa kana kuurayiwa
Kurapa kwekupisa: annealed, tempered, etc.
Hunhu nomenclature: kutengeserana mhando, kumanikidza mudziyo mhando, kudhirowa mhando, nezvimwe.
Ndeipi giredhi rakanakisa resimbi?
Iko hakuna "yakanakisa" giredhi resimbi, sezvo iro rakakwana giredhi resimbi rekushandisa rinoenderana nezvakawanda zvinhu, senge mashandisirwo anotarisirwa, zvemuchina uye zvemuviri zvinodiwa, uye miganhu yemari.
Simbi mamakisi anogara achishandiswa uye anoonekwa seyepamusoro akateedzana kubva kune yega yega mhando anosanganisira:
Carbon steels: A36, A529, A572, 1020, 1045, uye 4130
Alloy simbi: 4140, 4150, 4340, 9310, uye 52100
Simbi dzisina tsvina: 304, 316, 410, uye 420
Zvishandiso simbi: D2, H13, uye M2
JINDALAI ndiro boka rinotungamirira resimbi rinogona kupa magiredhi ese esimbi mucoil, sheet, pombi, chubhu, tsvimbo, bar, flanges, elbows, tees, etc. Ipa Jindalai pfungwa yekuvimba, uye iwe uchagutsikana nechigadzirwa.
