S355JR Lub kaum sab xis: 120 * 120 * 10 hli, 130 * 130 * 12 hli, 180 * 180 * 18 hli, 200 * 200 * 20 hli
Qhov kev ua tau zoo ntawm S355JR lub kaum sab xis steel feem ntau yog tshwm sim hauv peb yam: "siab zog," "zoo toughness," thiab "zoo weldability":
Mechanical Properties
High Yield Strength: Qhov no yog nws qhov tseem ceeb kom zoo dua, nrog qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa (muaj feem xyuam rau cov hlau nrog lub thickness tsawg dua los yog sib npaug li 16 hli), deb tshaj ntawm cov pa roj carbon zoo tib yam.
Tensile Strength: Lub zog tensile thaj tsam ntawm 470 txog 630 MPa.
Plasticity zoo: Qhov elongation feem ntau tsis tsawg dua 20-22%, pom cov yas zoo deformation muaj peev xwm thiab tsis tshua muaj kev puas tsuaj.
Kev ua tau zoo
Weldability zoo heev: Vim nws cov pa roj carbon tsawg (<0.24%) and alloy element content design, S355JR possesses excellent weldability, suitable for all conventional welding processes, with stable and reliable weld quality.
Yooj yim rau txheej txheem: Nws tuaj yeem raug txiav (nplaim, ntshav), drilled, txias- khoov, thiab lwm yam txheej txheem machining, ua kom yooj yim rau kev tsim cov txheej txheem nyuaj.
