S275J2 Hlau H Nqaj Rau Kev Siv
S275J2 H Ntaus Hlau Beam yog qhov tsis-alloy txheej txheem hlau.
Cov pa roj carbon (c): feem ntau nyob rau hauv ntau ntawm 0. 17% {2}}. 21%.
Silicon (si): feem ntau nyob ib ncig 0. 10% {2}}. 40%.
Manganese (MN): Cov ntsiab lus manganese feem ntau 0. 60% {2}}. 20%.
Phosphorus (p): Txwv rau 0. 035%.
Sulphur (s): Feem ntau tsis ntau tshaj 0. 035%,
Aluminium (AL): Ib qho nqi ntawm txhuas feem ntau ntxiv, feem ntau nyob ib ncig {{020% {2}}. 040%.
Tos lub zog: cov paib lub zog ntawm S275J2 yog teev rau qhov tsawg kawg nkaus ntawm 275MPA, uas txhais tau tias thaum muaj kev ntxhov siab txog 275MPA.
Tensile lub zog: lub zog tensile ntawm S275J2 Hlau H nqaj yog nyob rau hauv ntau ntawm {2}} mpa mpa. Lub zog tensile qhia tau qhov kev ntxhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus ua ntej tawg hauv lub taub hau tensile. Kev sib xyaw ua ke zoo ntawm cov paib lub zog thiab tensile lub zog ua kom cov qauv kev ncaj ncees thiab kev nyab xeeb ntawm cov khoom siv los ntawm cov hlau no.
Kev elongation: Qhov feem pua ntawm elongation feem ntau tsis tsawg dua 20%. Kev ntsuas kev ntsuas Elongation lub peev xwm ntawm cov hlau ua kom deform plastically ua ntej tawg.
Kev Cuam Tshuam: S275J2 H zoo li tus hlau muaj kev cuam tshuam zoo ntawm chav tsev kub.
S275J2 H tshooj Steel muaj los ntawm GNEE feem ntau yog tsim los ntawm cov pa roj Oxygen HASE Tom qab muaj cov tshuaj muaj tseeb, nws tau muab pov rau hauv ntau cov duab thiab tom qab ntawd cov khoom cam colled thaum kub. Kub dov pab ua kom cov qauv hlau mus rau cov khoom lag luam kawg. Thaum lub sij hawm kub dov txheej txheem, cov qauv grain ntawm cov qauv hlau yog ua kom zoo nkauj, uas tuaj yeem txhim kho cov khoom siv neeg kho tshuab.
