Kev sib piv ntawm Q235R thiab Q345R

Kev sib piv ntawm Q235R thiab Q345R

Cov lus saum toj no qhia tau hais tias tshwj tsis yog Element Si thiab Mn cov ntsiab lus sib txawv, lwm cov ntsiab lus txwv ntawm Q245R thiab Q345R yog tib yam. Raws li boiler steel weld kev ua tau zoo yog cuam tshuam los ntawm nws cov ntsiab lus tshuaj, tshwj xeeb tshaj yog rau cov ntsiab lus carbon. Raws li cov ntsiab lus carbon hauv cov hlau nce, steel plasticity txo qis, steel hardening tendency yuav nce, thiab tawg yuav yooj yim los tsim. Feem ntau steel phaj muaj ntau cov ntsiab lus alloy, ua ke lawv muaj kev cuam tshuam rau cov khoom siv hlau steel. Yog liCarbon sib npaugyog tus lej tseem ceeb rau kev suav cov hlau weld kev ua tau zoo. Feem ntau steel phaj nrog Ceq<0.45% has good weld performance.

Rau Q345R muaj ntau dua Mn cov ntsiab lus, nws CeQ yog 0.1% siab dua Q245R. Q345R notch rhiab heev yog qhov loj dua Q245R, tsis tshua muaj zog qaug zog ua rau nws yooj yim los tsim cov kab nrib pleb thaum vuam. Yog li hauv qee qhov kev thov ib puag ncig, nws yuav tsum tau txiav txim siab ntawm qhov nruab nrab uas tuaj yeem cuam tshuam rau 2 hom hlau no. Piv txwv li: nyob rau hauv ntub dej H2S kev nyuaj siab corrosion ib puag ncig, rau tsawg carbon steel q235r thiab Carbon Manganese steel q345r, Ceq<0.40%. As Q245R has lower Ceq, it has better H2S Stress Corrosion Resistance kev ua tau zoo.
