Cov Khoom Siv
Qib qib D275JR tau siv dav siv hauv ob qho tib si kev tsim kho thiab cov khoom lag luam vim nws lub zog sib luag, ductility, thiab weldability. Hauv kev ua haujlwm, nws yog feem ntau muab rau hauv daim ntawv ntawm ntev thiab ca disided rau welded lossis riveted steel qauv, uas yog kev sib tw steel, kab, trusses, thiab txhawb nqa kev ua haujlwm, thiab kev txhawb nqa kev lag luam, thiab kev txhawb nqa kev lag luam, thiab kev txhawb nqa kev lag luam, thiab kev ua haujlwm txhawb nqa, thiab kev txhawb nqa kev lag luam, thiab kev txhawb nqa kev lag luam, thiab txhawb nqa cov qauv.
Cov khoom siv no tau siv nyob rau hauv cov tuam tsev, txuas hniav, thiab cov chaw muaj kev nyab xeeb, qhov chaw txhim khu kev qha cov qauv kev ua tau zoo nyob rau hauv lub zoo li qub thiab muaj zog.
Hauv cov tshuab thiab tsim kev lag luam, S275JR tau ua haujlwm los ua cov khoom lag luam qis {1} Nyem, Shafts, Axles, thiab thav duab. Nws zoo heev machinity, formability cov zog tso cai rau kev ua haujlwm zoo thiab kev ua haujlwm nyob rau hauv lub teeb {{futy} luag tshuab tshuab.
Tsis tas li ntawd, cov hlau txoj kev weldability zoo ua rau cov neeg tsim qauv thiab cov kws sib sau ua ke ua kom nws zoo tshaj plaws rau cov haujlwm loj uas yuav tsum tau siv cov ntaub ntawv ruaj khov. S275JR cov versatility hla kev engineering thiab tshuab lub tsev ua kom pom dav dav {}}}} me ntsis kev lag luam tus nqi thiab haum rau ntau daim ntawv thov.
