Dab tsi yog astm A283 gr. C?
ASTM A283 GR. C yog ib nrab - rau - qhov qis zog carbon qauv txheem steel nyob rau hauv Astm txheem. Nws yog koob meej rau nws lub zog sib luag, zoo vinesity, thiab zoo heev - qhov kev siv lub zog nruab nrab.
Khoom Paub meej
- Txheem: Astm A283
- Lub zog yog: nruab nrab - - Qhov muaj zog roj carbon ua qauv
- Tshuaj lom neeg cov tshuaj:
C Tsawg dua los yog sib npaug rau 0.24%, mn tsawg dua los yog sib npaug rau 0.40%, si (th 2 hli)}0.15 - 0.40
- Cov Khoom Siv Neeg Kho Tshuab:
Ys ntau dua lossis sib npaug rau 205 MPa, ts 380 - 515 mpa mpa mpa,
- Cov yam ntxwv tseem ceeb: Heldability zoo heev, muaj zog yoog raws kev ua, tus nqi sib npaug ntawm - ua hauj lwm zoo
Ntxiv nrog rau cov khoom siv neeg yooj yim, cov tawv nqaij ntawm Astm A283 Qib C steel phaj tuaj yeem kuaj los ntawm kev poob phaus thiab qhov kev cuam tshuam rau kev poob qis.
1. Charpy V-} cov neeg tsis tshua cuam tshuam
Lub hom phiaj:Txhawm rau txiav txim siab qhov tawv ntawm cov hlau thiab ntsuas nws lub zuaj -- brittle hloov kub. Xyuas kom cov hlau phaj tuaj yeem nqus tau lub zog txaus tsis muaj lub zog tsis muaj zog nyob rau hauv cov kev cuam tshuam zoo hauv qab, tshwj xeeb tshaj yog thaum kub tsawg.
Qhov ntsuas tau:
- Kev cuam tshuam kev cuam tshuam lub zog: lub zog tau siv los ua kom tawg ntawm qhov ntsuas kub tshwj xeeb, piv txwv li tsis pub tsawg tshaj li 41j lossis qis dua li 413 ntawm qhov ntsuas kub).
- Zas {{0- rau -} brittle transition kub: Thaj av kub uas cuam tshuam lub zog nqus dej qis dua.
- Kev nthuav dav tom qab: Lub ntsej muag yas tom qab ntawm Notch tom qab cov quav me me, tseem ceeb rau kev ntsuas cov kev ntsuas nruj.
2. Kev nqis tes hnyav
Lub hom phiaj:Txhawm rau txiav txim siab qhov tawg - ntes muaj peev xwm ntawm cov hlau, tshwj xeeb ntsuas cov paib tuab kom muaj kev tsis txaus siab sai sai.
Qhov ntsuas tau:
- Shear Cheeb Tsam Feem Pua: Qhov no yog qhov ntsuas tus tub ntxhais. Feem ntau yuav tsum tsis pub tsawg tshaj 85% ntawm qhov kub tshwj xeeb.
- DWTT kub: Qhov ntsuas kub sib raug zoo ntawm qhov kev teev tseg shear cheeb tsam feem pua ua tiav.

ASTM A283 GR. C vs gr. D
Lub ASTM A283 tus qauv qhia meej meej cov qhab nia qib -}}}}}} D. Lawv qhov sib txawv li cas?
Lub ntsiab sib txawv lus dag nyob hauv cov ntsiab lus carbon cov ntsiab lus ntau, yog li ntawd ua rau sib txawv hauv cov khoom siv tshuab.

Vim li cas ASTM A283 Gr. C yuav tsum tau tua cov hlau?
Raug tua cov hlau yog tag nrho Dazidized siv cov ntsiab xws li silicon thiab txhuas thaum ua rau muaj kev sib tw ntsiag to hauv cov pwm, ua rau muaj kev sib tw thiab ntom sab hauv qauv.
Qhov no muab ATTM A283 GR.C, raws li ib tug neeg tua neeg, nrog ob peb lub ntsiab lus tseem ceeb:
- Ntau yam tsis zoo thiab ruaj khov: yuav luag dawb ntawm cov tshuab hluav taws xob sab hauv thiab lub zog tseem ceeb, muaj zog dua, ua kom muaj kev lees paub ntau dua.
- Superior Weldability: Cov tshuaj sib xyaw ua ke thiab microstructure ua rau nws tsis tshua muaj kev tawg thiab porosity thaum lub sij hawm - Zoo welded pob qij txha pob qij txha. Nov yog qhov tseem ceeb rau cov qauv welded tseem ceeb.
- Zoo dua qis - kub tawv: grain} kev kub ntxhov: grain} tua los ntawm kev tua txhuas los txhim kho qhov qis- kub ntawm cov hlau.
- Zoo hloov kho cov khoom lag luam: Ua tsaug rau nws cov qauv sib txawv thiab cov steel yog tsim nyog rau kev txias txias, ua tiav, yielding zoo dua nto zoo tom qab ua haujlwm.
