Siab zog steel phaj

Q460 yog lub zog muaj zog qis alloy steel. Txoj kev xaiv ntawm Q460: Nws qib steel yog ua ntej nrog "Q", sawv cev rau qhov taw tes tawm los, piv txwv li lub zog tawm los, ntawm cov hlau. Cov lej hauv qab no sawv cev tus nqi taw tes ntawm 460, uas sawv cev rau 460 megapascals. Megapascals yog mus rau 6th lub zog ntawm 10, thiab pascals yog chav tsev ntawm lub siab. Q460 yog ib hom hlau uas ua rau cov yas deformation tsuas yog thaum lub zog muaj zog nce mus txog 460 MPa. Qhov no txhais tau hais tias thaum lub zog sab nraud raug tso tawm, cov hlau tsuas tuaj yeem tswj tau qhov kev ntxhov siab thiab tsis tuaj yeem rov qab mus rau nws qhov qub. Lub zog no ntau dua li cov hlau zoo tib yam. Cov cim qhia qib zoo yog A, B, C, D, thiab E Q460, uas tsim nyog nce cov ntsiab lus ntawm microalloying ntsiab lus thaum ua kom muaj cov pa roj carbon tsawg. Kev ua haujlwm vuam zoo yuav tsum muaj cov pa roj carbon tsawg sib npaug ntawm cov hlau, thiab qhov nce ntawm microalloying ntsiab tsis tsuas yog ua kom lub zog ntawm cov hlau, tab sis kuj nce nws cov pa sib npaug. Tab sis hmoov zoo, qhov sib npaug ntawm cov pa roj carbon ntau yog me me, yog li nws yuav tsis cuam tshuam rau kev ua haujlwm vuam ntawm cov hlau.
