"J0" yog hais txog qhov tsawg kawg nkaus charpy cuam tshuam tus nqi ntawm 0 ° C yog 27J.
"J2" txhais tau tias qhov cuam tshuam tsawg kawg nkaus ntawm -20 ° C yog 27J.
S275 Daim Ntawv Qhia & Specification
EN 10025 S275 steel khoom, muaj pes tsawg leeg thiab cov ntaub ntawv sib npaug tuaj yeem pom hauv cov ntaub ntawv hauv qab no. Tag nrho cov ntaub ntawv ntawm DIN EN 10025-2 yog tib yam li BS EN 10025-2 thiab lwm lub xeev EU cov tswv cuab.

S275JR PLATE yog ib lub phaj hlau ua los ntawm cov hlau me me los yog carbon hlau. Cov phaj no muaj kev siv loj heev rau kev tsim vaj tsev, tsim khoom hauv cov nroj tsuag, tshuab tsim, thiab hauv kev tsuas. Cov phaj no yog ua los ntawm S275JR alloy uas muaj ntau yam hauv qhov xwm txheej.

Tshuaj muaj pes tsawg leeg
Cov ntaub ntawv 1, EN10025 S275J0, S275J2 thiab S275JR tshuaj lom neeg muaj pes tsawg leeg raws li kev tsom xam ladle yog muab rau hauv cov lus hauv qab no.
