Q235zoo tib yam carbon structural steel tseem hu ua A3 steel. Q sawv cev rau qhov txwv tsis pub dhau ntawm cov khoom no, thiab cov hauv qab no 235 yog hais txog tus nqi tawm los ntawm cov khoom no, uas yog nyob ib ncig ntawm 235MPa. Thiab raws li cov thickness ntawm cov khoom nce, nws cov nqi tawm los txo. Vim tias cov ntsiab lus ntawm cov pa roj carbon monoxide yog nruab nrab, qhov kev ua tau zoo yog qhov zoo, lub zog, plasticity thiab vuam cov khoom zoo sib xws, thiab nws yog qhov siv dav tshaj plaws.
Kev faib tawm
1
Q235A
tsis cuam tshuam
2
Q235B
yog 20 degree ib txwm kub cuam tshuam
3
Q235C
yog 0 degree cuam tshuam
4
Q235D
yog -20 degree cuam tshuam
Cov ntsiab lus tseem ceeb: Cov ntsiab lus sulfur ntawm A, B, C, thiab D txo qis; A thiab B muaj cov ntsiab lus phosphorus tib yam, C muaj cov ntsiab lus phosphorus siab tshaj plaws thib ob, thiab D muaj cov ntsiab lus phosphorus tsawg tshaj plaws.
Raws li GB/T 700-2006 tus qauv, carbon structural steel Q235 muab faib ua plaub qib: A, B, C, thiab D raws li metallurgical zoo. Cov tshuaj muaj pes tsawg leeg ntawm txhua qib ntawm steel yog:
