SM490 Kub Rolled Seem Steel H Be nqaj
SM490 H-Shaped Hlau (JIS G3106 Txuj Ci), "SM" txhais tau tias yam tsawg txhais tau tias H-ense Secture rau cov ntawv thov High-thauj.
Cov khoom siv ntawm SM49 {1}} hect steel yog cov ntsiab lus carbon yog (C Tsawg
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab ntawm SM490 H Zoo Li Tus Hlau Beam
Lub zog tensile: 570-700 mpa (tshaj cov nominal 490 MPa yuav tsum tau).
Tos lub zog: ntau dua lossis sib npaug zos rau 355 mpa (tuab tsawg dua lossis sib npaug nrog 16 hli).
Txo qis nrog nce thickness (piv txwv li, ntau dua lossis sib npaug rau 285 mpa rau 150-200 hli).
Txiaj: ntau dua los yog sib npaug rau 17% (thinner ntu) rau ntau dua lossis sib npaug nrog 23% (tuab tus qauv), ua kom nruj dua rau kev ntxhov siab.
Kev Cuam Tshuam Cov Khoom Siv: Loj dua lossis sib npaug rau 27 j ntawm -20 degree (rau cryogenic ib puag ncig).
Kev tsim khoom thiab kev ua
Ntau Lawm: Kub dov nrog tswj kev txias txias kom ua kom tau microstructure.
Kev Kho Cua sov: normizing los yog tempering rau kev ua kom zoo dua lub zog-ductancy tshuav nyiaj li cas; Quenching (xws li dej khov nab kuab) kom tau raws li qhov tshwj xeeb hardness.
Cov kev kho deg: hot-dip galvanizing (piv txwv li SM490yb) rau cov tubrog nkoj thiab kev xeb ib puag ncig.
Qhov Zoo Ntawm SM490 Hlau Tshooj
Siab zog-rau-hnyav piv: Haum rau kev ua haujlwm ntev thiab kev thauj khoom zoo.
Weldability: tsawg cov ntsiab lus cov pa roj carbon, zoo sib xws nrog Arc vuam thiab lwm yam tswv yim.
Corrosion Kuj: Galvanized variants (piv txwv li SM490YB) muab kev pabcuam txuas ntxiv hauv ib puag ncig hnyav.
