Tus qauv nqaj s355jr kub-dov hlau h nqaj

S355JR Cov Txheej Txheem H-nqaj yog qhov qis-alloy high-zog qauv hlau uas ua raws li cov qauv European uas ua rau Q345b hauv Suav cov qauv. Ntawm lawv, "sawv rau cov qauv hlau," 355 "txhais tau tias tsawg kawg yog 355MPA, thiab" JR "sawv ntsug tsis kam ntawm chav tsev kub.

Lub ntsiab siv tshuaj muaj zog tseem ceeb ntawm S355jr H-nqaj C-txaj yog C tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug lossis sib npaug 0.025%. Cov nyiaj rho tawm me me ntawm lwm cov khoom siv tau kuj tseem tuaj yeem muab ntxiv txhawm rau txhim kho kev ua haujlwm ntawm cov hlau.

Gnee muaj nyob rau hauv ntau qhov ntau thiab tsawg, nyob rau sab Europe dav flange h-nqaj), heb (European txheem nqaim pob zeb flange h-nqaj). Cov ntau thiab tsawg ntau nrog rau He100A (100 × 96 × 5 × 8), HE120B (120 × 6.5 × 11), thiab lwm yam.

Cov yam ntxwv ua tau ntawm S355jr H-Beach
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Muaj zog ntau, yam tsawg kawg yog lub zog ntawm 355MPA, tensile lub zog ntawm {}} mpa.
Cov txheej txheem: Cov qauv zoo, yooj yim txiav, khoov thiab tho.
Weldability: zoo heev weldability, tuaj yeem welded los ntawm ntau txoj kev vuam txoj kev.
Corrosion Kuj: Alloy Cov Ntsiab Lus yog ntxiv, corrosion tsis zoo.

Kub Rolling Txheej txheem: Qhov ntau lawm ntawm S355jr kub-rolled h-nqaj feem ntau yuav tsum tau cua sov thiab tom qab ntawd dhau ntawm cov mills uas yuav tsum tau ua.
Kev tswj kom zoo: thaum lub sijhawm ua tiav, peb yuav ua raws li kev ntsuas kev ntsuas zoo, suav nrog cov khoom siv tshuaj lom neeg ua kom paub tseeb tias cov khoom lag luam ua tau cov qauv thiab cov neeg siv khoom.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
