Siv Tsim Hlau Steel S45 {1}} 0 h nqaj

 

 

Tus s nyob rau hauv s45 0 j} j}} h-nqaj sawv rau cov hlau qauv; 45 {0} sawv ntsug rau qhov tsawg kawg los muaj zog ntawm 450 mpa (tuab tsawg dua lossis sib npaug nrog 16 hli); Thiab J0 sawv rau qhov tsawg kawg nkaus cuam tshuam lub zog ntawm 27 Joules ntawm 0 degree, ua kom muaj kev nyuaj ntawm kev kub ntxhov.

 

S45 {{{{{}} J0 Beams yog tsim rau kev siv hauv cov ntawv thov thauj khoom hauv cov tuam tsev thiab cov khoom siv hluav taws xob.
