Cov khoom siv dab tsi yog STKM 11A steel yeeb nkab?
JIS G 3445 Qib STKM 11A Mechanical Pipe yog cov khoom siv hluav taws xob qis qis uas muaj txog li 012% carbon thiab txog 060% manganese cov ntsiab lus uas yooj yim rau kev tsim thiab tsim. Cov kav dej no yog tsim raws li JIS cov lus qhia thiab hu ua cs kav lossis ms kav.
STKM 11A alloy yeeb nkab tshuaj muaj pes tsawg leeg: C (carbon) 0.12%, Si (silicon) 0.35%, Mn (manganese) 0.60 %, P (phosphorus) 0.04%, S (sulfur) 0.04%.
Mechanical zog: tensile zog yog 290N / mm² 1.
Daim ntawv thov teb: Txij li JIS G3445 STKM 11A cov yeeb nkab tshuab muaj lub zog nruab nrab, zoo weldability thiab ductility, nws tsim nyog rau ntau yam kev siv tshuab, xws li txuas hniav, tsev, tsheb, nkoj, thiab lwm yam. Tib lub sijhawm, nws kuj tuaj yeem ua tau. siv nyob rau hauv low-pressure fluid thauj pipelines thiab dav dav structural pipelines.
