ASME SA612 yog dab tsi?
ASME SA612 Siab lub nkoj phajua raws li ASME SA612 / SA612M tus qauv. Nws cov tshuaj muaj pes tsawg leeg yog nruj me ntsis tswj los xyuas kom meej qhov zoo ntawm cov hlau phaj. Cov tshuaj lom neeg tseem ceeb suav nrog cov ntsiab lus xws li carbon (C), silicon (Si), manganese (Mn), thiab muaj peev xwm ua tau cov ntsiab lus xws li chromium (Cr), npib tsib xee (Ni), niobium (Nb), thiab lwm yam.
Kev tswj cov tshuaj muaj pes tsawg leeg tshwj xeeb yog raws li hauv qab no:
Cov ntsiab lus carbon (C): Tsawg dua lossis sib npaug li 0.25%
Silicon (Si) cov ntsiab lus: ntawm 0.15% thiab 0.5%
Manganese (Mn) cov ntsiab lus: ntawm 1.0% thiab 1.5%
Phosphorus (P) thiab sulfur (S), raws li impurity ntsiab, yog tswj nyob rau hauv ib tug tsawg theem ntawm tsawg dua los yog sib npaug rau 0.025%.
