SS490 Mechanical Properties
Cov cuab yeej cuab tam ntawm cov qauv hlau no ua lub luag haujlwm tseem ceeb hauv nws txoj kev siv dav dav, nrog lub zog tensile thiab cov ntsiab lus tawm los yog cov yam ntxwv tseem ceeb tshaj plaws. Thaum piv nrog rau lwm cov qib steel, SS490 nthuav tawm lub zog tensile zoo dua, ib qho kev ntsuas uas cuam tshuam rau kev tsim qauv zoo heev. Lub zog tensile optimization ntawm SS490 yog ua tiav los ntawm kev ua tib zoo tswj ntawm cov ntsiab lus alloying, nrog rau kev cuam tshuam ntawm kev kho cua sov ntxiv rau qhov no.
Qhov taw tes tawm ntawm SS490, lwm yam cuab yeej cuab tam tseem ceeb, yog cuam tshuam los ntawm cov ntsiab lus alloying tam sim no, thiab tseem yuav raug txhim kho raws li txoj cai kev kho cua sov. Piv nrog rau lwm cov qib steel, qhov taw tes tawm ntawm SS490 steel yog nyob rau ntawm qhov kawg siab dua ntawm qhov teev, yog li ua kom muaj kev tsim cov khoom siv ruaj khov thiab ruaj khov.
Cov teebmeem ntawm cov ntsiab lus alloying thiab kev kho cua sov ntawm cov khoom siv kho tshuab ntawm SS490 ua rau nws tsis yog cov khoom ntawm kev xaiv rau cov qauv uas xav tau lub zog siab, tab sis kuj rau cov uas xav tau kev weldability thiab formability siab heev.
