Gnee tau cog lus rau kev lav phib xaub rau kev sib raug zoo, kev tsim kho tshiab, thiab kev ua haujlwm tshwj xeeb, txhawm rau muab kev ua haujlwm siab - zooJIS G3101 SS400 kub- dov zoo li cov kab hlaurau cov neeg siv khoom hauv tsev thiab thoob ntiaj teb.
Peb lub hom phiaj yog xa cov kev daws teeb meem, daws cov teeb meem kev sib tw, thiab ua tau raws li txhua tus neeg siv khoom xav tau nrog kev pabcuam txhim khu kev qha thiab kev tshaj lij.
SS400 yog cov qauv hlau uas tau teev tseg raws li JIS G3101 tus qauv. Thawj "S" sawv cev rau cov hlau, qhov thib ob "S" rau cov qauv, thiab "400" qhia qhov tsawg kawg nkaus tensile zog ntawm 400 MPa.
SS400 beams yog dav siv nyob rau hauv txuas hniav, tsev, tsheb, machinery moj khaum, thiab kev siv cov qauv siv vim lawv zoo weldability, machinability, thiab nruab nrab lub zog.

SS400 beams muab cov qauv zoo, weldability, thiab toughness, haum rau cov qauv siv dav dav uas qhov siab hardness lossis hnav tsis kam yog qhov tseem ceeb.
Cov khoom siv
SS400 zoo li tus steel beams yog dav siv nyob rau hauv:
Kev tsim choj: kab kab, kab, kab, thiab kab uas txhawb nqa nruab nrab - ncua choj.
Lub Tsev Ncej: Cov kab teeb thiab cov kab hauv cov vaj tsev nyob, kev lag luam, thiab kev lag luam.
Machinery & Vehicle Frames: Txhawb nqa, braces, thiab cov tswv cuab me me rau cov tshuab hauv paus thiab lub tsheb chassis.
General Structural Fabrication: Industrial platforms, warehouse frameworks, and auxiliary structural components.
Gnee's JIS G3101 SS400 kub- dov zoo li steel kab teeb muaj kev txhim khu kev qha zoo, weldability zoo heev, thiab dav siv tau thoob plaws hauv cov qauv, pej xeem, thiab kev lag luam.
Nrog rau kev txhawb nqa muaj zog, cov kev daws teeb meem tuaj yeem hloov kho, thiab lub peev xwm xa khoom thoob ntiaj teb, Gnee yog tus neeg muag khoom ntseeg siab rau siab - zoo SS400 cov kab teeb steel.
Q1: SS540 kab teeb yog dab tsi?
A:SS540 beams yog kub-kho cov qauv I-beams lossis H-beams ua los ntawm SS540 steel, siab-lub zog Japanese tus qauv (JIS G3101) cov qauv hlau. Lawv yog tsim los rau hnyav- kev tsim kho thiab kev lag luam tej yaam num uas yuav tsum tau muaj peev xwm ua tau zoo dua - cov kabmob.
Q2: Qhov ntau thiab tsawg thiab cov ntaub ntawv muaj nyob rau SS540 beams?
A:SS540 kab teeb muaj nyob rau hauv ntau qhov siab, flange widths, thiab thicknesses. Tus qauv ntev feem ntau yog li ntawm 6 mus rau 12 meters, thiab kab teeb tuaj yeem muab tau raws li I-beams, H-beams, lossis kev cai- txiav ntu raws li qhov yuav tsum tau ua.
Q3: Dab tsi yog cov khoom siv kho tshuab ntawm SS540 kab teeb?
A:Lawv muaj lub zog tensile ntawm 540-670 MPa, yield zog ntau dua los yog sib npaug rau 355 MPa, thiab elongation Ntau dua los yog sib npaug li 18%, ua rau lawv haum rau cov qauv kev ua haujlwm, txuas hniav, thiab kev txhawb nqa kev lag luam.
Q4: SS540 beams puas tuaj yeem welded thiab fabricated?
A:Yog, lawv muaj qhov zoo weldability thiab machinability. Cov txheej txheem vuam feem ntau suav nrog MIG, TIG, thiab arc vuam. Rau cov flanges tuab lossis lub vev xaib, preheating yuav raug pom zoo kom tsis txhob tawg.
Q5: SS540 beams feem ntau siv nyob qhov twg?
A:SS540 beams yog siv rau hauv kev tsim kho hnyav xws li siab - cov tsev nce siab, txuas hniav, cov nroj tsuag muaj kev lag luam, thiab kev tsim nkoj. Lawv lub zog siab tso cai rau kev ncua ntev thiab kev tsim qauv zoo dua.
Q6: SS540 piv nrog SS490 kab teeb li cas?
A:SS540 beams muab cov txiaj ntsig siab dua thiab lub zog tensile tshaj SS490 kab teeb, tso cai rau cov khoom hnyav dua -cov qauv kabmob thiab txhim kho cov kav ntev, thaum tseem tuav tau zoo weldability.
