H tshooj hea240 heb240 Q355D / s355j2 nqaj hlau
Q355D H-puab nqaj thiab S355J2 H-zoo li cov hlau nqaj yog ob lub ntsej muag sib txawv nrog cov khoom sib txawv thiab cov khoom siv neeg kho tshuab.
H-puab cov hlau ntawm lawv cov ntaub ntawv muaj cov khoom sib txawv, tab sis hais txog cov khoom loj, qhov ntau thiab tsawg ntawm Heas240 yog tsau thiab tsis cuam tshuam los ntawm cov khoom hloov.
Q355D H-nqaj seem thiab S355J2 H-ntu steel nqaj yog cov ntaub ntawv steel nyob hauv ob hom sib txawv, thiab muaj qee qhov sib txawv ntawm lawv cov tshuaj lom neeg.

Qhov txwv ntawm cov ntsiab lus ntawm cov ntsiab lus carbon ntawm s355j2 h steel profile yog siab me ntsis dua li ntawm Q355d. Ib qho ntxiv, S355j2 yuav muaj ntau yam yuav tsum tau ua rau cov ntsiab lus ntawm qee yam alloying ntsiab, tshwj xeeb tshaj yog rau cov ntsiab lus uas ua kom muaj kev cuam tshuam kub tsawg.
Tus "J2" hauv s355j2 h nqaj profile txhais tau tias qhov kev cuam tshuam nyuaj tus nqi ntawm {} degree yuav tsum ua kom tau raws li qhov kev ua tau zoo thiab muaj kev cuam tshuam zoo ua haujlwm hauv qhov chaw tsawg. Tus "D" hauv Q355d txhais tau tias nws yog qhov haum rau cov chaw qes.
