S235JR steel phaj
S235JR Khoom Description
S235JR yog ib feem ntawm tus qauv EN 10025, uas qhia txog cov txheej txheem xa khoom rau cov qauv hlau. Cov qauv no suav nrog ntau yam hlau, suav nrog S235JR, S235J0, S235J2, S275JR, S275J0, S275J2, S355JR, S355J0, S355J2 thiab S355K2.
Cov tshuaj muaj pes tsawg leeg ntawm S235JR suav nrog carbon, manganese, phosphorus, sulfur thiab silicon. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 235 MPa thiab lub zog tensile ntawm 360-510 MPa. S235JR tseem paub txog nws qhov kev cuam tshuam zoo, ua rau nws tsim nyog siv rau hauv cov ntawv thov uas nws tuaj yeem raug rau cov khoom hnyav.
Hauv qib steel S235JR, "J" thiab "R" sawv cev rau "J0" thiab "J2" feem. Cov no yog cov subgrades nyob rau hauv tsev neeg ntawm S235 steel qib txhais los ntawm lawv cov yam ntxwv toughness.
Lub npe "J" yog hais txog Charpy V-notch impact test, uas ntsuas lub zog nqus los ntawm cov khoom siv thaum tawg. Hauv qhov no, S235J0 thiab S235J2 yog ob qho tib si uas muaj qhov cuam tshuam tsawg kawg nkaus ntawm 27 J ntawm 0 degree thiab -20 degree, raws li.
Qhov kev xaiv "R", ntawm qhov tod tes, sawv cev rau "kev ua kom zoo li qub," ib qho kev kho cua sov tshwj xeeb los txhim kho cov khoom siv ntawm cov hlau. S235JR, S235J0, thiab S235J2 txhua tus muaj lub npe "R", txhais tau tias lawv tau ua haujlwm zoo thaum lub sijhawm tsim khoom.
Nyob rau hauv luv luv, lub "J" thiab "R" designations nyob rau hauv tsev neeg ntawm S235 steels hais txog subqualities txhais los ntawm lawv cov yam ntxwv toughness thiab cov txheej txheem kev kho cua sov. Thaum S235JR, S235J0 thiab S235J2 tag nrho cov npe "R", lawv muaj cov yam ntxwv sib txawv vim lawv "J" sub-designations.
