S3555j2 lub zog qis allolo qauv txheej txheem yog qhov muaj zog me me}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} {}} Lub zog siab uas ua raws li European cov qauv en 10025-2. Nws yog dav siv nyob rau hauv kev tsim kho thiab engineering tej yaam num vim nws tau ua ke ua ke ntawm lub zog, kev muaj zog, thiab weldability.
Nrog rau qhov tsawg kawg ntawm lub zog ntawm 355 MPa thiab lub tensile lub zog xws li 470-630 MPa, S355j2 muab kev txhim khu kev qha nyob rau hauv ob qho tib si zoo li qub thiab kev thauj khoom zoo nkauj.
Qhov kev cuam tshuam nrog tus qauv hlau no muaj cov kev cuam tshuam zoo, nrog lub npe hluav taws xob tsis kam, nrog cov tsis haum 27 J ntawm -20 degree, ua rau nws haum rau hauv ib puag ncig txias. Nws cov ntsiab lus muaj roj carbon qis kom yooj yim vuam thiab cov ntaub thaiv kev ua kom yooj yim, tso cai rau cov qauv txheej txheem nyuaj hauv cov choj, vaj tse, tshuab hluav taws xob, thiab tshuab hnyav.
Additionally, S355J2 plates are available in a wide range of thicknesses and can be cut-to-size or surface-treated for specialized applications, offering flexibility for diverse engineering needs.
