S355 Carbon Steel Phaj

S355 Qib S355JR, S355J2, S355J0 thiab S355K2 yield zog steel phaj yog cov tsis-alloy European tus qauv (EN 10025-2) cov qauv hlau, feem ntau siv tom qab S235 qhov xav tau ntau zog.S355JR, S355J2, S355J0 thiab S355K2 tsis-alloy steel phajmuaj zoo weldability thiab machinability, cia peb saib ntau cov ntsiab lus ntawm cov hlau no.
Kev txheeb xyuas qhov sib txawv S355:
S - sawv cev rau cov qauv hlau
355 - stands rau yam tsawg kawg nkaus yield zog (txawm hais tias nws yuav sib txawv raws li thickness, xa mus rau seem hauv qab no kom paub meej ntxiv)
Nquag S355 yuav muaj qhov hloov pauv raws li qhov cuam tshuam lub zog ntawm qhov sib txawv ntawm qhov kub thiab txias, vim tias cov hlau ua nkig ntau dua thaum kub poob. Yog tias koj tus qauv xav tau los tiv thaiv -20 degree, nws zoo dua thiab muaj kev nyab xeeb dua los xaiv S355J2.
S355JR - tuaj yeem tiv taus lub zog ntawm 27J ntawm +20 degree
S355J0 - tuaj yeem tiv taus lub zog ntawm 27J ntawm 0 degree
S355J2 - tuaj yeem tiv taus lub zog ntawm 27J ntawm -20 degree
S355K2 - tuaj yeem tiv taus lub zog ntawm 27J ntawm -30 degree (40J ntawm -20 degree)
Thiab qee zaum ua raws li tsab ntawv H, zoo li S355J2H, ntawm no H sawv cev rau ntu ntu.
S355 Qib S355JR, S355J2, S355J0 thiab S355K2 Yield Strength:
S355 Qib S355JR, S355J2, S355J0 thiab S355K2 yog lub npe raws li nws qhov tsawg kawg nkaus yield zog ntawm 355 Mpa (N / mm2), Txawm li cas los lub yield zog txo thaum koj mus rau hauv thickness saum toj no 16 hli rau cov khoom tiaj tus & hollow. ntu
