Cov yam ntxwv ntawm S275JR Steel
S275JR yog lub siab - cov pa roj carbon zoo steel ua raws li European qauv. Piv rau cov qauv carbon zoo tib yam, nws muaj kev txwv ntau dua ntawm cov ntsiab lus carbon, kev ua haujlwm ntau, thiab cov khoom seem xws li phosphorus thiab sulfur. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog tias European tus qauv S275JR carbon steel zoo ib yam li cov qib steel teev nyob rau hauv Tuam Tshoj tus GB / T 700 thiab GB / T 1591 tus qauv. Ob leeg koom nrog carbon structural steel thiab qis- alloy structural steel rau engineering thiab structural applications, thiab feem ntau yog xa hauv daim ntawv tsis kho. Tshwj xeeb, S185 sib raug rau Tuam Tshoj Q195, thaum S235 thiab S275 sib haum rau kuv lub teb chaws Q235 thiab Q275, feem. S235 sib raug rau Q235, thiab S275 sib raug rau Q275. Tsis tas li ntawd, tshwj tsis yog S185, tag nrho lwm cov qib steel yuav tsum muaj kev ntsuam xyuas ntawm 20 degree, 0 degree, thiab -20 degree.
Cov khoom ntawm S275J0 Steel
S275J0 ua raws tib yam tshuaj muaj pes tsawg leeg tus qauv raws li S275JR, tab sis qhov sib txawv tseem ceeb nyob rau hauv qhov yuav tsum tau muaj. S275J0 ua raws li cov qauv tshuaj muaj pes tsawg leeg xws li S275JR, txhais tau tias nws cov khoom tseem ceeb, xws li carbon, manganese, phosphorus, thiab sulfur, zoo ib yam hauv cov ntsiab lus. Tshwj xeeb tshaj yog, S275J0 yuav tsum muaj xoom-degree qhov kev ntsuam xyuas, qhia tau tias muaj kev tiv thaiv zoo dua ntawm qhov kub thiab txias.
Kev sib piv ntawm qhov sib txawv
Qhov sib txawv tseem ceeb ntawm S275JR thiab S275J0 nyob hauv lawv cov kev xav tau cuam tshuam. Tshwj xeeb, S275JR tsuas yog xav tau chav- ntsuas qhov kub thiab txias, thaum S275J0 yuav tsum tiv taus xoom-degree cuam tshuam. Qhov no qhia tau hais tias qhov zoo tshaj ntawm S275J0 nyob rau hauv qis dua - qhov kub thiab txias ib puag ncig. S275JR steel plays lub luag haujlwm tseem ceeb hauv kev tsim kho kev lag luam thiab ntau yam haujlwm engineering. Nws tseem yog ib qho tseem ceeb ntawm cov khoom siv rau cov tshuab hnyav xws li drilling rigs, hluav taws xob shovels, hluav taws xob log tsheb thauj khoom, excavators, thiab bulldozers. Tsis tas li ntawd, S275JR steel yog siv dav hauv ntau hom cranes thiab hydraulic kev txhawb nqa hauv cov mines thee kom ntseeg tau tias lawv ruaj khov thiab kav ntev.
