Dab tsi yog St35.8 sib npaug rau?
1. Suav Cov Qauv Sib Tham
GB 8163-10 # steel
Cov khoom siv txuam: St35.8 yog sib npaug rau 10 # steel ntawm Suav txheem cov qauv GB 8163 hauv cov khoom siv tshuaj lom neeg, thiab feem ntau yog siv cov txheej txheem kev siv tshuab, tshuab cov txheej txheem sib xws.
Kev sib piv sib piv:
Cov pa roj carbon (c): St35.8 yog hais txog 0. 17%}. 13% (txawv me ntsis, tab sis siv tau rau cov ntawv thov tswv yim);
Manganese (MN): St35.8 yog 0. 4%}}}} -0. 65%.
Lwm yam peev xwm teb
20 # steel: yog tias muaj zog dua lossis cov ntsiab lus carbon ntau, st35.8 tuaj yeem hais txog qee qhov xwm txheej, tab sis nws yuav tsum tau hloov kho raws li cov kev xav tau tshwj xeeb
2. Kev sib piv ntawm cov tsis tseem ceeb
| Lus | St35.8 (DIN 17175) | 10 # hlau (GB 8163) |
|---|---|---|
| Yield zog (mpa) | Ntau dua los yog sib npaug rau 225-235 (qhov kub thiab txias) | Ntau dua los yog sib npaug rau 205 (tuab tsawg dua los yog sib npaug rau 16 hli) |
| tensile lub zog (mpa) | 360-4804 | 335-4901 |
| Elongation (%) | Ntau dua los yog sib npaug rau 254 | Ntau dua los yog sib npaug rau 24 |
3. Daim Ntawv Thov Kev Sau Npe
Kev siv dej ua kua dej dav dav: xws li cov tshuab roj qis xws li dej thiab roj kis, uas ntsib daim ntawv thov ntawm GB 8163 txuj;
Kev tsim tshuab: Cheebtsam xws li cov roj thooj voos kheej kheej thiab cov kav dej txhawb nqa hydraulic yuav tsum ua kom tau raws li lub zog thiab kev ua tau zoo ntawm St35.8;
Lub tsev qauv qauv: siv rau teeb qauv teeb tsa lossis txuas, hloov mus rau cov kev xav tau nyob rau hauv cov tshuab kub ib txwm.
IV. Cov Qauv Qhia Thoob Ntiaj Teb
ASTM A106 GR.B (American txheem): Lub zog tensile yog ze rau St35.8 (ntau dua lossis sib npaug sib txawv, yog li nws yuav tsum tau hloov nrog kev ceev faj;
JIS G3454 Stpg370 (Japanese Txuj Ci): Lub Zog Japanese): Lub zog Japer yog zoo sib xws (ntau dua los yog sib npaug rau 215mpa), Haum rau nruab nrab thiab cov raj hluav taws xob tsis zoo.
Lub ntsiab
Cov tub ntxhais sib npaug khoom siv ntawm St35.8 yog GB {2}} # steel, uas nws muaj pes tsawg leeg, uas muaj kev sib hloov thiab kev ua tau zoo sib pauv ntawm kev tsim cov kev sib cav sib ceg. Rau lub zog siab lossis cov haujlwm ua haujlwm tshwj xeeb, 20 # steel lossis lwm cov ntaub ntawv thoob ntiaj teb tuaj yeem xaiv tau ua ke nrog cov tsis tau.
