S355JR Longitudinal Ncaj Seam Submerged Arc Welded Yeeb Nkab

Khoom Taw qhia ntawm S355 Longitudinal Ncaj Seam Welded Yeeb Nkab

S355JR longitudinal ncaj seam submerged arc welded yeeb nkab siv European tus qauv S355JR qis alloy siab - lub zog cov qauv hlau ua cov khoom siv hauv paus. Nws yog tsim axially nyob rau hauv ib kauj ruam siv JCOE precision txias forming thiab multi-wire submerged arc vuam txheej txheem. Cov khoom no muaj lub zog tawm los ntawm Ntau dua lossis sib npaug rau 355MPa thiab qhov cuam tshuam toughness ntawm Ntau dua lossis sib npaug rau 27J ntawm +20℃. Nws ob npaug -sab submerged arc weld muaj qhov tob tob tob, thiab qhov tsis yog{11}}kev ntsuas kev puas tsuaj dhau 99%. Ua ke nrog kev siv tshuab dav dav, cov yeeb nkab steel ua tiav qhov tseeb ntawm ± 0.1% D. Nws yog dav siv nyob rau hauv siab- bearing qhov tseem ceeb xws li cua turbine yees, siab - cov kav dej siab, thiab cov qauv hlau hnyav, thiab ua raws li cov qauv thoob ntiaj teb xws li EN 10210 thiab API 5L.

Kev ntsuam xyuas cov cuab yeej cuab tam ntawm S355JR longitudinal ncaj seam submerged arc welded yeeb nkab nruj me ntsis raws li EN 10210 tus qauv. Kev ntsuam xyuas ua kom ntseeg tau cov khoom siv: Ua ntej, kev ntsuas tensile yog ua los ntawm cov qauv ntawm cov khoom siv hauv paus thiab thaj chaw vuam kom paub tseeb tias lub zog tawm los (Ntau dua lossis sib npaug rau 355MPa) thiab lub zog tensile (470-630MPa); ib txhij, ib qho +20℃Charpy V- hom kev cuam tshuam yog ua los xyuas kom meej tias muaj zog cuam tshuam ntau dua lossis sib npaug ntawm 27J; bending kev ntsuam xyuas yog siv los ntsuam xyuas weld plasticity. Tag nrho cov ntaub ntawv xeem tau raug txheeb xyuas los ntawm lub koom haum thib peb, thiab daim ntawv tshaj tawm ua tiav suav nrog kev tshuaj ntsuam xyuas microstructure, muab ob npaug rau kev ruaj ntseg ntawm cov qauv.
