Qhov txawv ntawm steel qib C45 thiab lwm qib yog dab tsi?
1. Kev Taw Qhia rau 45 # Cov Khoom Uas Zoo Carbon Cov Qauv Hlau Qib
45 # steel yog cov khoom siv zoo carbon steel dav siv hauv kev tsim khoom. Nws cov khoom siv kho tshuab zoo heev thiab nws cov nqi kuj pheej yig.
C45 (1.0503) yog qhov nruab nrab carbon zoo hlau nrog lub zog siab. Italian UNI tus qauv steel qib C45 feem ntau yog siv nyob rau hauv lub xeev normalized vim tsis zoo hardenability. Thaum cov khoom siv kho tshuab xav tau, quenching thiab tempering kho yog siv. Txias deformation plasticity yog nruab nrab, thiab kev txiav ua haujlwm ntawm kev sib tsoo thiab kev ua haujlwm zoo yog qhov zoo dua li ntawm quenching thiab tempering. C45 yog ib lo lus nyob rau hauv tus qauv DIN, hu ua 45 steel nyob rau hauv lub teb chaws tus qauv, S45C nyob rau hauv tus qauv JIS, thiab 1045080M46 hauv ASTM tus qauv. Nws yog siv los tsim cov khoom uas muaj lub zog siab, xws li lub zog, ncej, piston pins, thiab machined qhov chaw, forgings, stamped qhov chaw, bolts, txiv ntseej, thiab cov yeeb nkab sib txuas uas tsis raug rau lub zog tseem ceeb.
2. Cov ntsiab lus ntawm nruab nrab carbon high-quality steel: Cov pa roj carbon zoo steel yog cov carbon steel nrog cov ntsiab lus carbon tsawg dua 0.8 feem pua. Cov hlau no muaj cov sulfur tsawg dua, phosphorus, thiab cov hlau tsis muaj hlau ntau dua li cov qauv hlau, thiab muaj cov khoom siv zoo dua qub.
3. C45 siv cov qib steel:
Suav GB txheem steel qib 45; Japanese JIS tus qauv steel qib S45C / S48C; German DIN cov khoom siv steel qib 1.0503; German DIN txheem steel qib C45; British BS txheem steel qib IC45/080A47; Fabkis AFNOR tus qauv steel qib CC45; Fabkis NF tus qauv steel qib C45; Italian UNI tus qauv steel qib C45; Belgian NBN tus qauv steel qib C45-1; Swedish SS txheem steel qib 1650; Spanish txheem steel qib F.114; AISI/SAE tus qauv steel qib 1045 hauv Tebchaws Meskas; International Organization for Standardization ISO standard steel qib C45E4. C45 Tus Qauv Ua Haujlwm: EN 10083 / 2-1991
4. Kev kho cua sov ntawm 45 # high-quality carbon structural steel: normalized, 850; Quenching, 840; Kev kub ceev, 600.
Kev xa khoom ntawm 545 steel high-quality carbon structural steel:
Muab tso rau hauv qhov tsis muaj cua sov kho lossis kho cua sov (annealed, normalized, lossis high-temperature tempered) xeev. Yog hais tias tus me nyuam yuav tsum tau nyob rau hauv lub tshav kub kho lub xeev, nws yuav tsum tau teev nyob rau hauv daim ntawv cog lus, thiab yog hais tias tsis tau teev, nws yuav tsum tau muab xa mus tsis muaj kev kho cua sov.
6. Tshuaj muaj pes tsawg leeg ntawm 45 # high-quality carbon structural steel:
Carbon C: {{0}}.42 ~ 0.50, silicon Si: Tsawg dua los yog sib npaug rau 0.4{{1{{12} }}}, manganese Mn: 0.50~0.80, sulfur S: Tsawg dua los yog sib npaug rau 0.045, phosphorus P: Tsawg dua lossis sib npaug li 0.045, chromium Cr : Tsawg dua lossis sib npaug rau 0.40, npib tsib xee Ni: Tsawg dua lossis sib npaug rau 0.40, molybdenum Mo: Tsawg dua lossis sib npaug rau 0.10.
Lus Cim: Cov khoom siv zoo carbon steel (GB / T699-1999):
Tsuas yog cov pa roj carbon (C) thiab qee qhov nyiaj ntawm silicon (Si) (feem ntau tsis pub tshaj {{0}}.40 feem pua) thiab manganese (Mn) (feem ntau tsis tshaj {{ 8}}.80 feem pua, txog li 1.20 feem pua ) alloy cov ntsiab lus uas yog siv rau deoxidation, hlau tsis muaj lwm yam alloy ntsiab (tsis suav cov seem seem). Hom hlau no yuav tsum ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab. Nws cov sulfur (S) thiab phosphorus (P) impurity cov ntsiab lus feem ntau tswj tau qis dua 0.035 feem pua. Yog tswj tau ntawm 0.030
