S355J2H txias- ua welded steel yeeb nkab yog dab tsi?
S355J2Hyog ib hom tshwj xeeb ntawmtxias - tsim welded structural steel yeeb nkabUa raws li European tus qauv EN 10219. Nws muaj qhov tsawg kawg nkaus yield zog ntawm 355 MPa thiab tshwj xeeb yog tsim los rau zoo heev toughness thiab cuam tshuam tsis kam ntawm qhov kub thiab txias, lav qhov tsawg kawg nkaus lub zog ntawm 27 J ntawm -20 degree.
Dab tsi engineering tej yaam num yog S355J2H txias-tsim welded steel kav feem ntau siv nyob rau hauv?
S355J2H txias- ua welded steel kavyog siv nyob rau hauv ntau yam engineering tej yaam num, xws li steel lug, civil engineering, thiab hnyav machinery. Nws lub zog siab, zoo heev qis- kub toughness, thiab weldability zoo ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov cheeb tsam txias, xav tau cov qauv, thiab cov ntawv thov kev lag luam marine.
Dab tsi yog qhov txawv ntawm S355J2H txias-tsim welded yeeb nkab thiab kub-tsim yeeb nkab?
Qhov txawv tseem ceeb yog qhov ntawdtxias- ua welded yeeb nkabyog tsim thiab welded los ntawm steel sawb ntawm chav tsev kub, thaum kub - cov yeeb nkab yog tsim nyob rau hauv high kub.Txias- cov kav dej khoovmuab qhov zoo ntawm qhov chaw tiav thiab qhov tseeb qhov tseeb, thaum kub - cov kav dej khoov feem ntau muaj cov phab ntsa tuab dua thiab, vim lawv qhov kub siab dua, cov khoom siv zoo dua ductility thiab toughness.
S355J2H txias-khoov welded kav siv tau nyob rau hauv qis- qhov chaw kub?
Yog lawm,S355J2H txias-khoov welded kavtuaj yeem siv rau hauv qhov chaw qis - qhov kub thiab txias. Lub npe "J2" lav qhov cuam tshuam lub zog tsawg kawg yog 27J ntawm -20℃. Nrog nws lub zog siab thiab zoo heev kub-kub toughness, cov yeeb nkab steel no yog tsim rau kev siv hauv cov cheeb tsam txias.
Dab tsi yog qhov yuav tsum tau cia rau S355J2H txias -bent welded steel kav?
Cov kev cai cia rauS355J2H txias-bent welded steel kavyog kom lawv qhuav thiab huv si, tsis txhob los nag thiab impurities, thiab tshem tawm xeb tam sim ntawd. Tom qab ntxuav, siab - cov kav dej zoo steel yuav tsum tau coated nrog cov roj los tiv thaiv - xeb ua ntej cia, thaum cov kav hlau steel yuav tsum tau siv sai li sai tau. Cov kav hlau yuav tsum tau muab khaws cia rau hauv cov pob khoom, feem ntau ruaj nrog cov hlua hlau.
