JIS Txheem H-Nqaj SS400 Hlau Beam
Cov ntsiab lus hom: SS400 yog cov qauv hlau teev los ntawm Japanese JIS qauv (Japanese muaj kev lag luam qauv). "SS" Stands rau "Txheej Txheem Hlau", thiab "400" txhais tau tias qhov tsawg kawg nkaus tensile zog σb ntawm cov hlau phaj yog 400MPA, uas yog rau cov hlau txheem carbon.
SS4 {0 {{4 4} h-nqaj} h-nqaj} h-nqaj Mackan (si), MN), phosphorus (p), leej faj (cov leeg). Cov ntsiab lus carbon yog nruab nrab ntawm 0. 16% thiab 0.22%, uas zwm rau cov hlau tsawg. Tus lej P thiab s nruj me ntsis, ob qho tib si tsawg dua 0.050%, vim tias P yuav nce txias rau cov hlau, thiab s yuav ua rau kub brittleness.
Cov Khoom Siv Neeg Kho Tshuab
Tos lub zog: Qhov tsawg kawg los lees lub zog ntawm SS400 kub-dov hlau feem ntau yog ntau dua lossis sib npaug nrog cov tuab tuab nrog cov tuab ntawm cov hlau. Thaum lub thickness ntawm cov hlau yog tsawg dua 16 hli, cov txiaj ntsig lub zog yog li 245MPA.
Lub zog tensile: lub zog tensile ntawm SS400 carbon hlau yog nruab nrab ntawm {mpa mpa, uas tuaj yeem tiv thaiv lub tsev tensile ntawm tsev lossis cov tshuab siv thaum siv.
Kev Txom Nyem: Qhov elongation ntawm SS400 Tsawg Cov Roj Hlau Loj dua los yog sib npaug rau 26%. Thaum raug rau qee cov qib ntawm nro lossis lwm yam tsis muaj zog, cov hlau tuaj yeem tsim cov qee yam yas ua kom tsis muaj kev rhuav tshem tam sim ntawd.
Kev cuam tshuam hluav taws xob: Qhov cuam tshuam lub zog ntawm SS400 hlau loj dua los yog sib npaug rau 27J.
Cov Khoom Siv Lub Cev
Weldability: SS400 H-puab cov txheej txheem hlau muaj qhov zoo weldability thiab yooj yim rau vuam thiab lwm yam kev ua haujlwm.
Kev Tsim Kho Txias: Yooj yim ua kev ua haujlwm txias xws li kev txiav thiab khoov.
SS400 h-nqaj muaj ntau yam kev qhia tshwj xeeb. Qhov siab ib txwm (H) Ranges los ntawm 100mm, cov Flange tuab (T2) yog 8mm, thiab qhov ntev yog {12}} m. Gnee kuj tseem tuaj yeem raug kho raws li cov kev cai tshwj xeeb.
