Dab tsi yog cov khoom siv qis alloy steel phaj?
Tsawg alloy steel phaj yog steel phaj nrog cov ntsiab lus tsis tshua muaj alloy. Qhov qis alloy steel phaj tam sim no nyob rau hauv kev ua lag luam feem ntau yog hais txog Q345B phaj. Feem ntau cov ntsiab lus alloy ntawm hom hlau phaj yog tsawg dua 3.5%. Vim tias cov ntsiab lus ntawm cov hlau tsis tshua muaj, cov hlau hlau phaj yog ntau dua corrosion-resistant, muaj zoo toughness, siab zog, thiab yog dav siv. Nws yog cov khoom siv vuam uas muaj qhov tshwj xeeb zoo. Nws tuaj yeem khaws cia rau hauv qhov qhib huab cua hauv qhov chaw uas muaj huab cua sib txawv, thiab tuaj yeem tiv thaiv corrosion los ntawm huab cua thiab dej vapor. Cov khoom siv saum npoo tuaj yeem muab cov rwb thaiv tsev zoo heev. Vim nws cov tawv tawv zoo, nws tuaj yeem ncab lossis curled raws li cov neeg xav tau tiag tiag, thiab nws muaj zog plasticity. Lub ntsiab tam sim no siv cov hlau tsis tshua muaj hlau phaj suav nrog kev tsim cov choj hlau phaj.Peb muaj ntau tshaj 15 xyoo ntawm kev tsim khoom thiab kev xa tawm, thiab peb muaj cov neeg ua haujlwm tshaj lij los muab cov lus teb ntxaws rau koj cov xaj. Yog tias koj muaj lus nug txog cov hlau tsis tshua muaj hlau, thov hu rau kuv.
