Thaum grey hlau tsis muaj lub zog ntsuas tau, qhov ntau rau lub zog tensile yog 20, 000 psi - 60, 000 psi. Kev cuam tshuam - Cov hlau nplaum muaj kev tiv thaiv ntau dua rau kev cuam tshuam, thiab muaj peev xwm tiv taus qhov tsawg kawg ntawm 7 ko taw phaus ntawm qhov cuam tshuam (piv rau 2 phaus ntawm kev cuam tshuam rau grey hlau).
Puas yog grey cam khwb cia hlau ductile los yog brittle?
Piv rau cov hlau niaj hnub ntau dua, cov hlau grey muaj tsis muaj zog tensile thiab ductility; Yog li ntawd, nws qhov kev cuam tshuam thiab kev poob siab yuav luag tsis muaj nyob.
Puas yog cov hlau grey ntau dua cov hlau?
Piv lawv lub cev lub cev.
Cov hlau muaj zog dua, zoo dua ductility, tshav kub-tiv taus thiab tawv dua li grey hlau, yog li nws muaj daim ntawv thov dav dua, Qee qhov xwm txheej, cov hlau nplaum tuaj yeem hloov cov pa roj carbon steel.
Qhov txawv ntawm cov hlau cam thiab grey hlau yog dab tsi?
Qhov txawv yog dawb cam khwb cia hlau nta cementite hauv qab nws nto, whereas grey cam khwb cia hlau nta graphite hauv qab nws nto. Cov graphite tsim cov tsos ntawm cov xim grey, thaum cov cementite tsim cov xim dawb.
Puas yog grey cam khwb cia hlau malleable?
Grey cam khwb cia hlau muaj peev xwm ua kom muaj zog thiab tiv taus corrosion. … Malleable hlau muaj kev poob siab zoo, yog ductile thiab machinable heev. Nws lub ntsiab detractor yog tias nws shrinks thaum nws txias. Qhov no yog vim nws poob ntim thaum nws txias.
