Kub Rolled Txheej Txheem Hlau H Nqaj S355JR S355JT2 Hem280
Tus ntoo khaub lig-ntu qhov ntev ntawm HEM280 qauv HAR BAR yog: qhov siab (H) yog 310 lub hli; Flth Dav (B) yog 288 hli; Web tuab (t₁) yog 18,5 hli; Flange tuab (t₂) yog 33 hli.
S355JR Cov Txheej Txheem Hlau H Tsua yog mus rau European txheem qis-alloy High-zog qauv hlau, uas ua raws li lub en {3}} txheem.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm S355jr H Beam khoom siv: carbon (c) tsawg dua lossis sib npaug ntawm {0. toughness. Cov txiaj ntsig lub zog ntawm s355jr h-nqaj hlau qauv sib txawv nrog cov tuab.
Nws yog 355 MPa thaum cov tuab tuab yog tsawg dua lossis sib npaug nrog kev txo qis (xws li 34}} mm mm); Lub zog tensile yog 470-630 mpa. Qhov kev cuam tshuam nyuaj yog ntau dua lossis sib npaug rau 27 j ntawm +20 degree.
