I. Cov ntsiab lus txhais thiab cov qauv txheej txheem ntawm as1163 steel yeeb nkab
1. Cov chaw tsim khoom thiab evolution
AS1163 yog tus qauv rau cov qauv hlau teeb hollow cov qauv los ntawm cov qauv hauv Australia. Nws thawj zaug yog xyoo 1981 (raws li 1163: 1981), thiab cov ntawv tam sim no yog 1163: 1991 / AMDT 2: 1996. Cov qauv no feem ntau qhia meej txog cov kev xav tau rau txias- Cov kab ke wollow thiab seaming {} Cov kab ke), thiab duab plaub).
2. Cov neeg ua haujlwm hauv chav kawm thiab lub zog qib
Cov qib siab: lawv feem ntau muab faib ua peb qib: C250, C450, thiab C450. Cov naj npawb sawv cev rau qhov tsawg kawg nkaus zog zog (Chav: MPA).
Piv txwv li:
- C250: Tawm lub zog ntau dua los yog sib npaug rau 250 MPa
- C350: Tawm lub zog ntau dua los yog sib npaug rau 350 MPa
- C450: Tawm lub zog ntau dua lossis sib npaug nrog 450 MPa
Daim ntawv qhia "L0" qhia tau tsawg - kub cuam tshuam nyuaj ua kom zoo (xws li C350L0).
Cov Khoom Siv: Feem ntau cov hlau ua hlau (Q235, Q255, Q355) thiab tsawg Alloy Steel, nrog qee qhov muaj ov- corrosion ntsiab.
