S275jr vs A36
Cov qauv
A36 Hlau: Ua raws li ASTM A36 / A36M cov qauv, thiab yog Asmeskas tus qauv carbon structural steel.
S275JR Steel: Ua raws li European tus qauv EN10025-2 (piv txwv li, EN10025-2: 2014 lossis EN10025-2: 2019), thiab yog European txheem carbon structural steel.
Tshuaj muaj pes tsawg leeg
A36 Hlau: Cov khoom siv tshuaj tseem ceeb suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P), thiab sulfur (S). Tshwj xeeb, cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.25%, cov ntsiab lus manganese nyob nruab nrab ntawm 0.8% thiab 1.2% (qhov ntau yuav txawv me ntsis nyob ntawm qhov chaw), cov ntsiab lus phosphorus tsawg dua lossis sib npaug li 0.04%, thiab cov ntsiab lus sulfur tsawg dua lossis sib npaug li 0.05%.
S275JR Steel: Cov khoom siv tshuaj tseem ceeb kuj muaj xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), thiab sulfur (S), nrog rau cov kab mob sib kis xws li tooj liab (Cu). Siv lub phaj steel thickness Tsawg dua los yog sib npaug rau 40mm ua piv txwv, nws cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.21%, manganese cov ntsiab lus tsawg dua lossis sib npaug li 1.50%, phosphorus cov ntsiab lus tsawg dua lossis sib npaug li 0.035%, sulfur cov ntsiab lus tsawg dua lossis sib npaug li 0.035%, thiab cov ntsiab lus nitrogen tsawg dua lossis sib npaug 0.

Mechanical Properties
A36 Hlau: Muaj lub zog siab, siab toughness, zoo plasticity, thiab cov khoom ua haujlwm. Lub zog tawm los yog feem ntau Ntau dua lossis sib npaug rau 360MPa (qee qhov chaw hauv xeev Loj dua lossis sib npaug rau 250MPa, tab sis A36 steel feem ntau muaj lub zog ntau dua).
S275JR Steel: Yield zog nce mus txog 275MPa (qee cov ntaub ntawv qhia tias nws cov ntsiab lus tawm los tsis qis dua 270MPa, tab sis 275MPa yog nws tus qauv tus nqi), lub zog tensile nyob nruab nrab ntawm 430 ~ 580MPa, thiab elongation tom qab tawg ntau dua lossis sib npaug li 14%. Tsis tas li ntawd, S275JR steel kuj muaj kev cuam tshuam zoo toughness thiab dabtsi yog khoov zog.

Delivery Conditions thiab Daim Ntawv Thov
A36 Hlau: Siv dav hauv kev tsim kho, txuas hniav, thiab tshuab tsim khoom, xws li hauv kev tsim cov kab, kab, kab hlau, thiab steel thav duab rau cov tsev; vaj tse thiab hauv paus rau cov motors loj thiab ntau lub twj tso kua mis; thiab precision qhov chaw ua.
S275JR Steel: Kev xa khoom muaj xws li kub- dov, tswj- dov, thiab normalized. Nws kuj tseem siv dav hauv kev tsim kho, txuas hniav, thiab kev tsim cov tshuab, tab sis feem ntau nyob rau hauv cov khoom siv uas yuav tsum tau muaj kev thauj khoom siab -cov kabmob muaj peev xwm thiab cov tawv tawv zoo, xws li txuas hniav, siab- cov tsev tsim, cov nroj tsuag, ntau yam khoom siv, cov kabmob, cov khoom siv sib kis, cov khoom siv hauv nkoj tsim, thiab cov khoom siv hauv kev lag luam roj tank thiab cov khoom siv hluav taws xob.
