Cov Khoom Siv
Lub nkoj nkoj thiab cov ntawv thov tawm tsam
Q235B hlau daim hlau feem ntau yog siv hauv kev tsim kho hauv Hull, lawj, thiab sab nrauv platform. Cov cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau 0.22%) thiab zoo tshaj veldability ua kom ntseeg tau. Ua ke nrog cov khoom zoo thiab cuam tshuam tsis kam, cov hlau tuaj yeem tiv taus cov tub rog thiab kev ntxhov siab.
Muaj Machinery Thiab Cov Khoom Siv Hnyav
Rau kev siv siv, Q235B cov pa roj carbon hlau tau ua haujlwm hauv lub tshuab, thiab cov cuab yeej txhawb nqa. Nrog nws lub tensile muaj zog txog 500 MPa thiab elongation ntawm 20-25%, cov khoom siv tuaj yeem ua haujlwm tsis txaus siab, thiab hnyav thauj khoom tsis muaj deformation lossis tsis ua tiav.
Automotive thiab Kev Lag Luam Tsheb Thauj
Q235B daim hlau kuj tseem siv rau hauv tsheb chassis, tsheb ciav hlau tsheb ciav hlau, thiab cov vaj huam sib luag. Nws cov kev txhim khu kev qha ...- Cov kabmob muaj peev xwm, thiab cov khoom siv tsis zoo, thiab raug tsim kho tshiab. Cov hlau sib ntsib ob GB / T 700 thiab GB / T 3274 tus qauv, ua kom zoo sib xws nrog kev siv cov ntawv thov siab.
