S275J2 Hlau Hlau Thickness Elongation xaiv: Z15, Z35
Kev qhia tawm ntawm S275J2 Steel phaj: Chav kawm 1 yog siab dua li chav kawm 2, uas yog siab dua li chav kawm 3.
Cov qib elongation elongation rau s275j2 steel phaj: Z35 yog siab dua z25, uas yog siab dua z15.
Qhov laj thawj yog vim li cas S275J2 Steel phaj tau siv nyob rau hauv kev tsim khoom lag luam yog tias S275J2 steel phaj muaj ntau yam khoom thiab tus nqi qis. Lub siab -} kev ua tau zoo ntawm S275J2 Steel phaj thaum siv tau muaj kev qhuas thiab lees paub los ntawm kev tsim kev lag luam. Tom qab ntawd, vim kev lees paub ntawm kev sib raug zoo, nquag siv hauv kev tsim khoom lag luam thiab txhim kho cov khoom siv los ntawm cov ntaub ntawv tsim khoom, S275J2 steel hlau tau siv ib qho ntawm cov khoom siv steel phaj feem ntau yog cov siv hlau.
