S355jr cov txheej txheem hlau nqaj
S355jR H tshooj Hlau muaj lub zog zoo tshaj plaws, Weldability thiab cuam tshuam nyuaj ntawm chav tsev kawm 24 degree thiab tau dav siv hauv kev tsim kho, tshuab ua tshuab, tshuab thiab ua yeeb yam engineering. Tus s hauv s 355jr sawv rau cov hlau txheej txheem; 355 sawv rau qhov tsawg kawg nkaus lub zog ntawm 355 mpa; Thiab JR sawv rau Charpy cuam tshuam kev xeem (tsawg kawg lub zog nqus dej: ntau dua lossis sib luag rau 27 j) ua tiav ntawm 20 degree.

Qhov zoo ntawm s355jr hlau nqaj h
Lub zog siab: Ntsuas kom muaj txiaj ntsig zoo zog (355 MPa) thiab tensile lub zog (490-630 MPa).
Weldability: Tsawg cov pa hluav taws xob txo cov kev pheej hmoo tawg.
Durability: kev txhim khu kev qha ua tau zoo hauv cov khoom lag luam huab cua.
