### 1. Dab tsi yog qhov txawv ntawm A500 Gr B thiab Gr C?
Qhov sib txawv ntawm ASTM A500 qib B thiab qib C yog lawv lub zog txhua yam. Qib C muaj qhov ntau dua tsawg dua cov txiaj ntsig lub zog thiab lub zog C. Piv txwv li Learnes, hauv qib C muaj txiaj ntsig zoo li ntawm 46 KSI (320 MPA). Ib yam li ntawd, qhov tsawg kawg nkaus tensile lub zog rau qib B yog 58 kSI (400 MPA), thiab rau qib C, nws yog 62 ksi (427 MPA). Qhov no ua rau qib c muaj zog thiab feem ntau xaiv rau cov kev siv hnyav hnyav. Qib C Tej zaum kuj muaj cov tshuaj sib txawv me ntsis kom ua tiav qhov muaj zog dua.
### 2. Dab tsi yog AQUM A500 qib B siv rau?
ASTM A500 qib B feem ntau siv hauv cov ntawv thov cov txheej txheem rau cov tsev thiab kev tsim kho. Nws lub zog zoo - {{3} Kev tsim qhov hnyav, thiab cov cim kev loj, thiab ntau hom kev lag luam racks thiab cov laj thawj. Nws yog ib qho muaj ntau yam, txias - tsim steel tubing uas yog dav muaj thiab nquag teev los ntawm engineers thiab kws tsim khoom.
### 3. Dab tsi yog astm A500 qib C specification?
Lub ASTM A500 Qib C Cov Lus Qhia Tshwj Xeeb Qhov Yuav Tsum Tau Ua Rau Cov Khaub Ncaws Txias Thiab Seamless Carbon Steel Tubing Hauv Round, Square, thiab duab dhos ua si. Nws cov ntsiab lus tseem ceeb muaj qhov tsawg kawg nkaus lub zog ntawm 46 (320 MPA) thiab qhov tsawg kawg nkaus ntawm 62 kSI (427 MPA) rau cov duab sib dhos (qhov tseem ceeb me ntsis rau cov hlab). Qhov tshwj xeeb kuj suav nrog kev txwv ntawm cov tshuaj muaj tshuaj lom neeg (piv txwv li, cov ntsiab lus mangan, thiab cov kev ntsuam xyuas mangle), thiab kev ntsuam xyuas dav dav kom paub tseeb thiab ua tau zoo rau cov hom phiaj.
### 4. Dab tsi yog Astm A500 Qib A?
ASTM A500 Qib A yog ib qib txheej txheem yas ua kom muaj zog ntawm 33 KSI (230 MPa) thiab lub zog tsawg kawg ntawm 45 ksi (310 mpa). Vim nws lub zog qis, nws yog feem ntau siv nyob rau hauv cov ntawv thov tsawg dua lossis qhov chaw ntawm kev sib tw, tus tes taw, thiab cov me tub kos duab.
### 5. Dab tsi yog qhov sib txawv ntawm Qib B thiab Qib C Steel?
Nyob rau hauv cov ntsiab lus ntawm astm A500 steel, qhov sib txawv ntawm qib B thiab qib C thiab cov khoom siv txhua yam, tshwj xeeb lawv lub zog. Qib C tus hlau tau ntau dua cov khoom tawm los thiab tensile lub zog tseem ceeb tshaj qib b steel. Qhov no txhais tau tias qib C tuaj yeem tiv thaiv ntau dua cov khoom thauj thiab kev ntxhov siab ua ntej deforming lossis poob siab, ua kom haum rau ntau yam haujlwm xav tau. Cov tshuaj lom neeg muaj kuab lom kuj tseem tuaj yeem hloov kho kom ua tiav qhov muaj zog no. Hauv kev nkag siab dav dua A500, "Qib C" thiab "sib txawv, nrog C) feem ntau tsis lees txais lub zog siab dua lossis cov khoom zoo dua.
