S355JR steel phaj

S335 JR- ib qho tseem ceeb ntawm cov qauv steel nrog qhov tsawg kawg nkaus yield zog ntawm 355 N / mm². S355 tau siv dav hauv cov txheej txheem engineering thiab kev tsim kho kev lag luam, S355 muaj cov txiaj ntsig siab thiab lub zog tensile thiab tau muab nrog ntau yam kev kho mob thiab kev sim kev xaiv kom ntseeg tau tias nws yog cov hlau siv tau zoo hauv koj cov haujlwm ntau yam.

S355 structural grade (S) nqa yam tsawg kawg nkaus yield zog ntawm 355 N / mm² m², JR lub npe lees paub tias cov hlau tau undergone longitudinal Chary V-Notch cuam tshuam kuaj ntawm 27J (Joules) ntawm chav tsev kub. Lwm cov npe Charpy suav nrog J0, J2 thiab K2.

Cov qib ntawm cov hlau no yog npaj rau kev ua haujlwm uas tsis muaj kev tsim lossis khoov yuav tsum tau ua. Cov qib no tuaj yeem raug bolted, riveted thiab welded nyob rau hauv ib tug ntau yam ntawm cov qauv thiab fabricated khoom xws li txuas hniav, lub thawv girders, cranes thiab lwm yam structural tej yaam num.

Cov qhab nia ntawm SANS 50025 /EN 10025-2xa mus rau qhov tsawg kawg nkaus yield zog ntawm txhua qib rau thicknesses tsawg dua los yog sib npaug zos rau 16 hli. Cov hlau yuav tsum raug xaiv raws li qhov yuav tsum tau muaj zog.Lub JR, J0 & J2 cov lus xaus yog xa mus rau cov kev xav tau sib txawv. Qhov nruab nrab cuam tshuam lub zog tus nqi ntawm 27 Joules yuav tsum tau ua tiav ntawm qhov loj me me hauv qhov kev taw qhia ntev hauv txhua qhov teeb meem.
