Puas yog Q235 lub zog txo nrog nce thickness?
Teb: Yog. 16 ~ 40mm: 225MPa; 40 ~ 60mm: 215MPa; 60 ~ 100mm: 205MPa.
Puas yog Q235 haum rau vuam?
Teb: haum heev. Tsawg carbon sib npaug, mos kub- thaj tsam cuam tshuam, tsis yooj yim rau tawg, haum rau arc vuam thiab roj tiv thaiv vuam.
Q235 puas tuaj yeem txias - khoov?
Teb: Yog. 180℃txias dabtsi yog khoov, mandrel txoj kab uas hla d=1.5a (a =} tuab), tsis yog tawg.
Qhov txawv ntawm Q235 thiab Q355 (yav tas los Q345) yog dab tsi?
Teb: Q235 muaj lub zog tawm los ntawm 235MPa, cov ntsiab lus carbon tsawg, yog pheej yig dua, thiab welds zoo dua; Q355 muaj zog dua (355MPa), yog kim dua, thiab siv rau cov khoom hnyav.
Yuav ua li cas xaiv Q235 qib hauv kev tsim kho? A: Qhov kub thiab txias ntawm cov qauv → B; nyob ib ncig ntawm 0℃→ C; -20℃txias txias → D; static load tsis tseem ceeb → A.
