Yog S275 pheej yig tshaj S355?
S355 steel muaj tus nqi siab dua li S275 homCov. Dua li ntawm tus nqi no sib txawv, S355 txheej txheem hlau feem ntau nyiam vim nws tus qauv qis dua piv rau S275 hom. Nws tseem zoo dua thaum nws tsim nyog yuav tau mus txog cov yam ntxwv tau muaj nuj nqis ntawm cov neeg kho tshuab hauv lub xub ntiag ntawm cov kev txwv hnyav tag nrho.
Dab tsi yog qhov txawv ntawm S235JR thiab S355JR?
Dab tsi ua rau lawv sib nrug, txawm li cas los xij, yog tiasS3555jr muaj zog duaCov. S355JR muaj 355 mpa kom lub zog piv rau 235 MPa muab los ntawm S235JR, ob qho tib si rau thicknesses txog li 16 hli. Qhov no zoo dua thiab ntau dua lub zog ua rau nws txoj kev xaiv zoo tshaj plaws rau cov khoom siv tawv thiab ntau dua yog qhov tseem ceeb.
Dab tsi yog qhov txawv ntawm S235 thiab S275 vs S355?
Piv txwv li,S355 steel muaj cov feem ntau dua ntawm cov pa roj carbon tau muab piv rau S275 thiab S235 Steel, ua kom nws muaj zog thiab nruj dua. Ib yam li ntawd, S275 steel muaj ntau manganese tshaj s235 steel, uas txhim kho nws lub zog thiab tawv.
Dab tsi yog qhov txawv ntawm S275 thiab S275JR?
Qhov sib txawv nkaus xwb ntawm ob qho yog tiasS275JR phaj tau cuam tshuam kev sim ntawm 27 Joules ntawm chav tsev kub, thaum S275 Phaj tsis muajCov. Qhov no txhais tau tias S275jr phaj yog qhov tsim nyog rau cov ntawv thov uas yuav tsum muaj kev feem ntau S275jr phaj nrov zog.
