S235J2 steel sib npaug yog dab tsi?
S235J2 yog sib npaug rauASTM A283 Qib C, nrog zoo sib xws lub zog thiab weldability. Lub hardness ntawm S235J2 yog dab tsi? Qhov raug Brinell hardness (HB) ntawm S235J2 yog 120-170 HB, nyob ntawm thickness thiab kev kho cua sov.
Puas yog S235 qis carbon steel?
S235 yog qib ntawm cov qauv hlau nrog cov ntsiab lus qis carbon, nws qhov nyiaj siab tshaj yog 0.22% los ntawm qhov hnyav.
S355J2 steel yog dab tsi?
Qhov tseem ceeb, S355J2 yogmicro- alloyed structural steel uas zoo rau ntau yam kev siv tshuab engineering. Nws muaj qhov zoo heev weldability nrog max CEV=0.47 rau txhua qhov sib txawv, thiab nws feem ntau xa nrog cov ntsiab lus silicon tswj kom tso cai rau cov khoom zoo galvanizing.
Dab tsi yog qhov txawv ntawm S235 thiab S355 steel?
Piv txwv li,S355 muaj lub zog tawm los ntawm 355 MPa, uas yog 50% siab dua li ntawm S235. Txawm hais tias lub zog sib txawv, cov tshuaj muaj pes tsawg leeg ntawm S235 thiab S355 yog ze li qub.
