Lub kaum sab xis Steel Bar SS400 JIS
Thaum yuav khoom thiab siv lub kaum sab xis zoo li no, nws yog ib qho tseem ceeb heev kom nkag siab txog nws cov yam ntxwv ntawm cov khoom thiab specifications.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm SS400 steel lub kaum sab xis yuav tsum ua raws li cov kev cai ntawm JIS G 3112. Nws cov khoom tseem ceeb suav nrog hlau (Fe), carbon (C), silicon (Si), manganese (Mn) thiab lwm yam.Ntawm lawv, cov ntsiab lus carbon yuav tsum nyob nruab nrab ntawm 0.18% -0.28%, cov ntsiab lus silicon yuav tsum nyob nruab nrab ntawm 0.12% -0.30%, thiab cov ntsiab lus manganese yuav tsum nyob nruab nrab ntawm 0.70% -1.00%.Tsis tas li ntawd, lub kaum sab xis steel yuav tsum muaj qee cov ntsiab lus ntawm phosphorus (P) thiab sulfur (S) kom nws cov tawv tawv thiab lub zog.
Cov khoom siv kho tshuab ntawm SS400 profile steel yuav tsum ua raws li cov cai ntawm JIS G 3112. Nws lub zog tensile (σb) yuav tsum tsis txhob tsawg dua 400N / mm², thiab nws lub zog tawm los (σs) yuav tsum tsis pub tsawg dua 240N / mm².Nyob rau tib lub sijhawm, qhov elongation (δ) ntawm cov kub dov steel lub kaum sab xis yuav tsum tsis pub tsawg dua 22%.Cov khoom siv kho tshuab ua kom ntseeg tau tias SS400 lub kaum sab xis steel muaj peev xwm thauj khoom siab thiab ua haujlwm ntev hauv ntau yam kev thov.
Mechanical Properties
Kev ua tau zoo
SS400 sib npaug lub kaum sab xis muaj cov txheej txheem zoo thiab tuaj yeem siv rau kev khoov, ncaj, shearing, stamping thiab lwm yam kev ua haujlwm.Nyob rau tib lub sijhawm, hom kub dov steel profiles kuj muaj kev vuam zoo thiab tuaj yeem ua tau raws li ntau yam kev xav tau vuam.Thaum lub sijhawm ua haujlwm, kev saib xyuas yuav tsum tau them nyiaj rau kev tswj qhov kub thiab txias kom tsis txhob tawg thiab deformation ntawm lub kaum sab xis steel.
Corrosion Resistance
SS400 lub kaum sab xis steel muaj qee qhov kev tiv thaiv corrosion, tab sis nws yooj yim rau xeb hauv qhov chaw ntub dej.Txhawm rau txhim kho nws cov kev tiv thaiv corrosion, qhov saum npoo ntawm lub kaum sab xis hlau tuaj yeem coated nrog txheej txheej ntawm cov xim pleev xim.Tsis tas li ntawd, thaum lub sijhawm thauj mus los thiab khaws cia, lub kaum sab xis steel yuav tsum tau qhuav thiab huv si kom tsis txhob raug ya raws ntev.
Nyob rau hauv luv luv, Japanese txheem lub kaum sab xis steel SS400 yog lub kaum sab xis zoo steel uas yog dav siv nyob rau hauv ntau yam kev tsim kho, txuas hniav, nkoj, tsheb thiab lwm yam teb.Nws yog ib qho tseem ceeb heev kom nkag siab txog nws cov khoom siv thiab cov lus qhia tshwj xeeb thaum yuav khoom thiab siv hom lub kaum sab xis steel.Thaum siv, yuav tsum tau them nyiaj rau kev saib xyuas thiab kev saib xyuas kom ntseeg tau tias nws muaj kev nyab xeeb thiab kev pabcuam lub neej.
