Q235 steel yog dab tsi?
Q235 yog lub teb chaws tus qauv carbon structural steel. "Q" yog hais txog lub zog tawm los, thiab "235" qhia tias lub zog tawm los Ntau dua lossis sib npaug rau 235 MPa. Yav tas los hu ua A3 steel, nws yog cov feem ntau siv lub hauv paus steel hauv kev tsim kho.
Q235 ua raws li cov qauv dab tsi?
Nws ua raws li GB / T 700-2006 "Carbon Structural Steel." Hlau daim hlau rau cov qauv tsim ua raws li GB / T 19879-2015.
Q235 yog dab tsi?
Nws tau muab faib ua plaub qib: A, B, C, thiab D, qhov txawv ntawm qhov qis- qhov kub thiab txias cuam tshuam toughness thiab impurity cov ntsiab lus, nrog qib D yog qhov zoo tshaj plaws.
Dab tsi yog qhov txawv ntawm Q235 thiab Q355?
Q235 yog cov pa roj carbon zoo tib yam (yield zog 235 MPa); Q355 yog qis- alloy siab- lub zog steel (yield zog 355 MPa), nrog kwv yees li 50% siab zog.
Vim li cas Q235 dav siv hauv kev tsim kho?
Nws muaj lub zog nruab nrab, zoo plasticity, zoo heev weldability, yog ib qho yooj yim rau txheej txheem, thiab muaj tus nqi qis, ua rau nws haum rau feem ntau cov qauv tsev.
