Cov pa roj carbon steel yog cov hlau-carbon alloy nrog cov ntsiab lus carbon ntawm 0.0218 feem pua rau 2.11 feem pua. Kuj hu ua carbon steel. Nws feem ntau muaj me me ntawm silicon, manganese, sulfur thiab phosphorus. Feem ntau cov pa roj carbon steel, qhov siab dua cov ntsiab lus carbon, qhov hardness ntau dua thiab siab dua lub zog, tab sis cov yas qis dua.
Kev faib tawm
(1) Cov pa roj carbon steel tuaj yeem muab faib ua peb pawg raws li lub hom phiaj: carbon steel qauv, carbon hlau hlau thiab cov hlau tsis pub txiav. Carbon structural steel yog muab faib ua ob hom: engineering steel thiab tshuab tsim cov qauv hlau.
(2) Raws li txoj kev smelting, nws tuaj yeem muab faib ua qhib hearth steel thiab converter steel.
(3) Deoxidation txoj kev yuav muab faib ua boiling steel (F), tua steel (Z), semi-static steel (b) thiab tshwj xeeb tua steel (TZ).
(4) Carbon steel can be classified into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25%-0.6%) and high carbon steel (WC>0.6 feem pua ) hais txog cov ntsiab lus carbon.
(5) Raws li cov hlau zoo, carbon hlau tuaj yeem muab faib ua cov pa roj carbon zoo tib yam (ntau dua phosphorus thiab sulfur cov ntsiab lus), zoo carbon steel (tsawg phosphorus thiab sulfur cov ntsiab lus), thiab qib high-qib steel (qis phosphorus thiab sulfur). cov ntsiab lus). ) thiab premium qib steel.
Hom
Carbon steel qauv
Qib: Case Q235-A·F, uas txhais tau tias σs=235MPa.
Qib annotation: Q yog lub zog tawm los qib A (ABCD qib 4), F Boiling Steel.
Nta: Tus nqi qis, cov txheej txheem zoo heev (xws li weldability thiab txias formability).
Daim Ntawv Thov: General engineering cov qauv thiab cov khoom siv tshuab dav dav. Xws li Q235 tuaj yeem ua los ntawm bolts, ceev, pins, hooks thiab tsis tshua muaj qhov tseem ceeb ntawm cov khoom siv thiab rebar, steel, steel reinforcement thiab lwm yam.
High quality carbon steel qauv
Qib: Piv txwv 45, 65Mn, 08F.
Qib annotation: ncaj qha sawv cev rau lub lab ntawm cov ntsiab lus carbon ntawm cov hlau.
Daim ntawv thov: Non-alloyed steels rau kev tsim cov khoom siv tshuab tseem ceeb feem ntau yog siv tom qab kev kho cua sov.
Common steel tooj thiab siv
08F, cov pa roj carbon tsawg tsawg, zoo plasticity, tsis muaj zog, siv rau stamping qhov chaw xws li tsheb thiab ntsuas vaj tse.
20, zoo plasticity thiab weldability, siv rau cov khoom uas tsis muaj zog yuav tsum tau thiab carburizing qhov chaw, xws li hoods, vuam ntim, me shafts, ceev, washers thiab carburizing zog.
45,40Mn, tom qab quenched thiab tempered, muaj zoo mechanical zog thiab yog siv rau mechanically stressed machines.Parts, xws li iav, txuas rods, tshuab cuab tam spindles, thiab lwm yam.
Cov iav zoo li no tuaj yeem siv cov hlau no ↓
60, 65Mn steel muaj lub zog siab; siv los tsim ntau yam kev sib tw, cov npoo ntawm lub log, lub log qis qis.
Cov pa roj carbon steel
Qib: Piv txwv li, T12 steel txhais tau tias WC =1.2 feem pua carbon tool steel.
Qib annotation: Ntau txhiab cov ntsiab lus carbon ntawm T ntxiv rau hlau.
Nta: Nws belongs rau eutectoid steel thiab hypereutectoid steel. Nws muaj zog thiab hardness thiab zoo hnav tsis kam. Nws yog tsim rau kev tsim ntau yam tsawg-ceev txiav cov cuab yeej.
Common steel tooj thiab siv:
T7, T8: Tsim cov khoom uas yuav tsum tau muaj zog los tiv thaiv qee yam kev cuam tshuam. Xws li sledgehammer, punch, chisel, cov cuab yeej siv ntoo, txiab.
T9, T10, T11: Tsim cov cuab yeej uas tsis tshua muaj kev cuam tshuam thiab siab hardness thiab hnav tsis kam. Xws li cov kais dej, xyaum me me, tuag, tes pom cov hniav.
T12, T13: Ua cov cuab yeej tsis muaj kev cuam tshuam. Xws li cov kab mob, scrapers, rab chais, ntsuas cov cuab yeej.
Cam khwb cia hlau
Qib: Piv txwv li, ZG200-400 qhia cam khwb cia hlau nrog σs=200 MPa thiab σb=400 MPa.
Kev ua tau zoo: Casting kev ua tau zoo tsis zoo dua li cam khwb cia hlau, tab sis txhua yam khoom zoo dua li cam khwb cia hlau.
Daim ntawv thov: Nws yog tsuas yog siv rau kev tsim cov duab complex, siab mechanical kev xav tau, thiab nws yog ib qho nyuaj rau siv lub forging thiab lwm txoj kev ntawm kev tsim cov khoom tseem ceeb nyob rau hauv cov txheej txheem, xws li lub tsheb lub gearbox plhaub, lub coupler thiab coupling ntawm locomotives thiab tsheb.
