Koj puas paub qhov twg yog qhov zoo dua, American standard steel phaj A36 lossis Q235B?
Shandong Kungang Hlau Technology Co., Ltd. tsom rau kev tsim thiab muag cov hlau phaj, thiab peb muaj kev paub nplua nuj thiab lub koob npe nrov hauv kev ua lag luam. Thaum muas cov hlau phaj, nws yog ib qho uas yuav hnov ib qho kev sib piv ntawm Asmeskas tus qauv hlau daim hlau A36 thiab Q235B. Ob hom steel phaj no muaj qee qhov sib txawv hauv kev ua haujlwm. Peb yuav muab koj cov lus piav qhia ntxaws txog lawv cov kev ua tau zoo los ntawm ntau qhov kev xav thiab pab koj txiav txim siab yuav khoom zoo. Ua ntej, cia peb sib piv ob daim hlau no ntawm lub zog. Lub zog tawm los ntawm Asmeskas tus qauv steel phaj A36 yog 250MPa, thiab lub zog tensile yog 400-550MPa, thaum lub zog ntawm Q235B steel phaj yog 235MPa, thiab lub zog tensile yog 375-500MPa. Los ntawm cov ntaub ntawv no, nws tuaj yeem pom tias lub zog ntawm American standard steel phaj A36 yog me ntsis siab dua Q235B, uas ua rau nws tsim nyog rau siv nyob rau hauv tej yaam num uas yuav tsum tau ntau zog txhawb.
Qhov thib ob, cia peb piv lawv cov tshuaj muaj pes tsawg leeg. Cov tshuaj muaj pes tsawg leeg ntawm American standard steel phaj A36 muaj carbon (C) cov ntsiab lus ntawm 0.25%, sulfur (S) cov ntsiab lus ntawm 0.05%, thiab phosphorus (P) cov ntsiab lus ntawm 0.04%, thaum Q235B steel phaj muaj carbon (C) cov ntsiab lus ntawm 0.22 Cov ntsiab lus sparse (S) ntawm 0.05%, thiab phosphorus (P) cov ntsiab lus ntawm 0.045%. Los ntawm qhov kev xav ntawm cov tshuaj muaj pes tsawg leeg, tsis muaj qhov sib txawv ntawm ob hom hlau daim hlau, ob qho tib si ntawm cov khoom siv carbon lub luag haujlwm steel thiab muaj qhov zoo weldability thiab machinability.
Tsis tas li ntawd, muaj qee qhov sib txawv ntawm kev tiv thaiv corrosion ntawm American standard steel daim hlau A36 thiab 0235B. Vim yog cov ntsiab lus siab carbon ntawm American standard steel phaj A36, nws yog nquag mus corrosion nyob rau hauv ib puag ncig nrog high humidity. Q235B steel phaj muaj corrosion kuj zoo nyob rau hauv ib puag ncig. Rau cov haujlwm engineering zoo tib yam, xaiv Q235B steel phaj tuaj yeem tiv thaiv cov qauv zoo dua los ntawm kev xeb. Tom qab ntawd, peb kuj yuav tsum xav txog qhov tseem ceeb ntawm weldability. Lub American standard steel phaj A36 muaj qhov zoo weldability thiab tuaj yeem txuas nrog siv cov txheej txheem vuam. Txawm li cas los xij, Q235B steel phaj muaj qee yam teeb meem vuam vim nws cov ntsiab lus qis. Hauv qee qhov haujlwm uas xav tau kev vuam zoo, xaiv Asmeskas tus qauv steel phaj A36 yuav txhim khu kev qha. Zuag qhia tag nrho, muaj qee qhov sib txawv ntawm Asmeskas tus qauv hlau daim hlau A36 thiab Q235B hais txog lub zog, tshuaj muaj pes tsawg leeg, kev tiv thaiv corrosion, thiab coalability. Yog tias koj xav tau kev txhawb zog siab dua thiab kev tiv thaiv corrosion zoo dua, koj tuaj yeem xaiv Asmeskas tus qauv steel phaj A36. Yog tias koj muaj kev xav tau ntau dua rau kev vuam zoo, koj tuaj yeem xaiv Q235B steel phaj.
