Q420qnh Weathering hlau rau choj tsim kho
Q420qh yog cov huab cua siab ua haujlwm tshwj xeeb tsim rau cov choj engineering. Daim ntawv "Q420" qhia tau tias nws tsawg zog zog lub zog ntawm 420 MPa, ua kom cov khoom siv zoo tau zoo tshaj plaws rau cov qauv thauj khoom. Daim ntawv "QNNH" DNOTES Choj (Q) thiab corrosion tsis kam (NH), qhia nws lub peev xwm superior kom tiv thaiv cov neeg hauv lub cev.
Cov hlau no muaj cov khoom siv xws li tooj liab, phosphorus, chromium, thiab npib dense, adherent oxide txheej rau saum npoo. Qhov txheej txheem tiv thaiv no tau txo cov nqi ntawm corrosion, ua rau nws {{zaus} lub sij hawm tiv taus cov pa roj carbon me. Tsis zoo li cov neeg tsoos Choj hlau uas yuav tsum tau pleev xim ntau, q420qnno tus nqi thiab ib puag ncig ntawm kev tshem tawm qhov kev xav tau rau kev tiv thaiv corrosive niaj zaus.
Q420qnh tseem muaj weldability zoo thiab formability, tso cai yooj yim fabrication rau hauv cov choj ua si. Nws cov siab tawv ntawm tsawg kub ua kom muaj kev txhim khu kev qha hauv cov huab cua hnyav hauv kev ua phem. Dav siv nyob rau hauv ntev-cann Los ntawm kev saib xyuas kev tu thiab txuas ntxiv lub neej, Q420qnh tau dhau los ua kev xaiv tshiab rau niaj hnub ua rau kev ntseeg tsis tu ncua thiab tus nqi ua haujlwm.
