EF S275J2 Kub Rolled Txheej Txheem Hlau H Be BAR
S275J2 H-nqaj yog cov qauv tsis-alloy qauv hlau muaj rau S275 series nrog lub zog zoo thiab tshuabsiab. Qhov "J2" hais txog kev cuam tshuam cov kev cuam tshuam nyuaj ntawm cov khoom ntawm qis kub. Cov qib kev kawm no feem ntau yog siv rau cov ntawv thov cov txheej txheem uas xav tau lub zog siab thiab kev ua kom zoo.
S275J2 Cov Qauv Txheem Hlau yog muab nyob rau hauv daim ntawv ntawm kub-rolled h-nqaj. Nws yog cov kab hlau teeb nrog H-zoo li tus neeg hla kev thiab cov khoom muaj peev xwm siv tau rau kev siv hauv cov tsev, cov choj thiab lwm yam haujlwm hauv Civiling engineering.
Cov tshuaj lom neeg muaj kuab lom ntawm S275J2 qauv H-ntu Steel feem ntau suav nrog:
Cov pa roj carbon (c): {{0. 16% - 0. 22%
Manganese (MN): 1.10% {2}}. 60%
Silicon (Si): tsawg dua los yog sib npaug rau 0. 55%

Sulphur (s): tsawg dua los yog sib npaug rau 0. 045%
Tooj liab (Cu): tsawg dua los yog sib npaug rau 0. 55%
S275J2 Kub Rolled steel muaj cov cuab yeej siv hauv qab no:
Paib lub zog: ntau dua los yog sib npaug rau 275 mpa
Lub zog tensile: {410 - 560 mpa mpa
Elongation: ntau dua los yog sib npaug rau 22% (tuab tsawg dua los yog sib npaug rau 16 hli)
Cuam tshuam tus nqi: ntau dua los yog sib npaug rau 27 j (ntawm -20 degree)
S275J2 H tshooj hlau tuaj yeem yooj yim welded siv txhua txoj kev vuam. Thaum vuam, gnee yuav nruj me ntsis ua raws li cov kev vuam tsim nyog kom muaj cov khoom siv me me ntawm cov khoom siv. S275J2 H tshooj hlau peb muab cov hlau ntawm cov hlau tuaj yeem yog galvanized, pleev xim lossis coated los tiv thaiv corrosion, nyob ntawm ib puag ncig cov xwm txheej thiab npaj siv.
S275J2 Kub dov H-nqaj yog siv nyob rau ntau cov ntawv thov suav nrog: kev tsim kho vaj tse thiab txuas ntxiv; hnyav; txhawb nqa qauv rau tshuab; Muaj cov tshuaj ntxuav thiab cov tais tais; Crane kev txhawb nqa qauv; Tubrog nkoj thiab sab nraud huab cua, thiab lwm yam.
