JIS G3101 SS400 LSAW Pipe

JIS G3101 tus qauv yog dab tsi?
JIS G 3101 yog cov khoom siv hauv Nyij Pooj rau kub Rolled steel daim hlau, nplooj ntawv, strips rau kev siv dav dav. Cov txheej txheem zoo kub dov SS400 steel yog ntau txhim khu kev qha nyob rau hauv nws tensile zog tshaj SS330 steel.

JIS G3101 SS400 ncaj seam submerged arc welded yeeb nkab yog ib qho ncaj seam submerged arc welded steel yeeb nkab uas ua raws li Japanese Industrial Standards (JIS G3101). Nws tsuas yog siv SS400 qib carbon structural steel li raw khoom. Cov tshuaj muaj pes tsawg leeg ntawm SS400 steel yeeb nkab feem ntau suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P) thiab sulfur (S). Ntawm lawv, cov ntsiab lus carbon tsawg, feem ntau yog qis dua 0.16%, uas pab ua kom cov weldability zoo thiab toughness ntawm cov hlau.
Lub zog tawm los ntawm SS400 LSAW Carbon Steel raj feem ntau yog nyob ib puag ncig 235 MPa, thiab lub zog tensile nyob nruab nrab ntawm 360-510 MPa. Nws muaj siab plasticity thiab toughness thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj zog ntawm cov khoom siv dav dav.
