SIB 400yog ib hom qauv steel qib tau teev tseg raws li Japanese Industrial Standard JIS G3192. Nws yog lub npe hu rau nws zoo plasticity, zoo heev weldability, thiab ruaj khov mechanical kev ua tau zoo.
SS400 feem ntau yog tsim los ntawm cov hlau, nrog rau cov nqi ntawm cov pa roj carbon monoxide thiab cov kab sib txuas kom ntseeg tau tias tsim nyog rau kev tsim kho thiab kev tsim kho tshuab.
Vim nws tus nqi -kev ua tau zoo thiab cov khoom siv kho tshuab uas ua tau raws li cov qauv kev cai dav dav, SS400 tau dhau los ua cov khoom siv hauv ntau qhov kev lag luam, suav nrog kev tsim kho, kev tsim khoom siv tshuab, thiab kev tsim kho vaj tse.
Lub ntsiab lus ntawm JIS Standard 80 × 80 × 7 Lub kaum ntse ntse hlau loj
Lub npe 80 × 80 × 7 yog hais txog tus ntoo khaub lig-sectional qhov ntev ntawm lub kaum sab xis steel:
Thawj 80 hli qhia qhov ntev ntawm ib ceg
Qhov thib ob 80 mm qhia qhov ntev ntawm lwm ceg
Lub 7 hli nruab nrab yog lub thickness ntawm lub kaum sab xis
Qhov kev qhia tshwj xeeb no txhais tau tias muaj lub kaum ntse ntse sib npaug, qhov twg ob txhais ceg yog qhov sib npaug. Lub thickness 7 hli muab kev sib npaug ntawm cov load-cov kabmob muaj peev xwm thiab cov qauv kev ruaj ntseg, ua rau nws haum rau nruab nrab- daim ntawv thov load.
Basic Mechanical Properties of SS400 Angle Steel
