JIS SM490 sib npaug hlau cov kauj ruam
SM490 sib npaug ntawm cov khoom lus qhia
SM490 lub qub steel yog ib hom qauv hlau qauv steel nquag siv hauv kev tsim kho, engineering thiab tsim cov ntawv thov. Lub npe "SM490" hais txog cov khoom siv tau tawm los lub zog, uas yog kwv yees li 490 MPa. Cov pwm muaj lub zog siab tshaj plaws, kev ua qauv zoo nkauj thiab muaj kev sib tw weldability zoo heev, thiab yog siv dav hauv qhov hnyav- muaj zog thiab kav ntev yog qhov tseem ceeb.
