Cov ntawv thov tseem ceeb ntawm S235J0 yog cov haujlwm ua haujlwm uas cov khoom raug cuam tshuam rau qhov txias lossis qhov sib txawv ntawm qhov kub thiab txias, yuav tsum muaj kev ruaj ntseg toughness ntawm 0℃los tiv thaiv nkig tawg.
Common siv muaj xws li:
Sab nraum zoov steel qauv: choj, kis tau tus yees, lub teeb ncej, thiab sab nraum zoov staircases nyob rau hauv temperate climates.
Lub tsev thiab kev tsim kho: Cov qauv tsim, kev txhawb nqa, thiab lub ru tsev trusses rau unheated warehouses, industrial halls, los yog cov tsev nyob rau hauv cov cheeb tsam uas muaj lub caij ntuj no txias.
General engineering thiab machinery: Cheebtsam rau cov khoom siv ua liaj ua teb, tsheb thauj mus los chassis, thiab tshuab ua haujlwm nyob rau hauv tsis yog - qhov chaw txias arctic.
Infrastructure thiab kev nyab xeeb cov ntsiab lus: Guardrails, txoj kev taug kev, thiab kev nkag mus rau lub platform uas raug rau lub caij ntuj sov poob.
Qhov laj thawj tseem ceeb ntawm kev xaiv S235J0 tshaj S235JR: Nws tau lees paub qhov cuam tshuam qhov hnyav ntawm 0℃muab qhov kev nyab xeeb ntxiv tiv thaiv qhov tsis ua hauj lwm tam sim ntawd hauv cov cua txias, ua rau nws muaj kev xaiv ntau hauv European thiab thoob ntiaj teb cov lej rau cov qauv hauv huab cua nrog qhov txias txias.
1. S235J0 steel yog dab tsi?
