Q460 alloy steel phaj nrog hnyav tuab

Kev piav qhia:

Q460 yog cov hlau tsis tshua muaj hlau. Q sawv cev rau lub zog ntawm cov hlau, 460 sawv cev rau 460 MPa, mega yog 6 lub zog ntawm 10,

thiab Pa yog lub siab ntsuas Pascal. Q460 txhais tau hais tias cov yas deformation ntawm cov hlau tsuas yog tshwm sim thaum lub zog ntawm cov hlau

nce mus txog 460 MPa, uas yog, thaum lub zog sab nraud raug tso tawm, cov hlau tsuas tuaj yeem tuav lub zog ntawm lub zog thiab tsis tuaj yeem rov qab los.

rau nws qhov qub. Lub zog no ntau dua li cov hlau zoo tib yam.

Raws li kev ua kom muaj qhov sib npaug qis, Q460 tsim nyog nce cov ntsiab lus ntawm microalloying ntsiab. Kev vuam zoo

kev ua tau zoo yuav tsum muaj cov pa roj carbon tsawg sib npaug ntawm cov hlau, thiab qhov nce ntawm microalloying cov ntsiab lus nce lub zog ntawm cov hlau.

thaum tseem nce cov pa roj carbon sib npaug ntawm cov hlau. Hmoov zoo, qhov sib npaug ntawm cov pa roj carbon ntxiv yog me me, yog li nws yuav tsis cuam tshuam rau

weldability ntawm cov hlau.
