Icyuma cya S275JR

EN 10025 S275 Icyuma (S275JR, S275J0 & S275J2)
EN 10025 S275 Icyuma nicyiciro cyicyuma kitavanze, nkuko EN10025 ibivuga, S275 ibyuma byoroheje bigabanywa cyane muri S275JR (1.0044), S275J0 (1.0143) na S275J2 (1.0145). Ibintu bimwe na bimwe bya S275 byoroheje biruta S235, kandi biri munsi ya S355.
S275 ibikoresho bishaje ni St44 ukurikije Ubudage, icyiciro cyiza cyahoze gihwanye niki gikurikira:
EN10025 S275JR (1.0044) - St44-2 muri DIN 17100
S275JO (1.0143) - St44-3U muri DIN17100
S275J2 (1.0145) - S275J2G4 muri EN 10025: 1993
EN10025 S275JR Ibisobanuro (Kugenwa)
Urutonde rukurikira rusobanura EN10025 S275JR ibisobanuro
“S” ni ibyuma byubaka;
“275” bivuga imbaraga nke z'umusaruro ni 275 MPa zapimwe n'ubugari bw'ibyuma ≤ 16mm.
“JR” bivuze ko agaciro ntarengwa ka charpy ingaruka ku bushyuhe bwicyumba ari 27J.
“J0” bivuga byibuze ingaruka zingirakamaro kuri 0 ° C ni 27J.
“J2” bisobanura agaciro ntarengwa kuri -20 ° C ni 27J.
S275 Urupapuro rwamakuru & Ibisobanuro
EN 10025 S275 ibikoresho byibyuma, ibihimbano nibikoresho bisa murashobora kubisanga mumibare ikurikira. Urupapuro rwose rwamakuru ya DIN EN 10025-2 ni kimwe na BS EN 10025-2 nibindi bihugu bigize Umuryango w’ubumwe bw’ibihugu by’Uburayi.

S275JR PLATE ni isahani yicyuma ikozwe mubyuma byoroheje cyangwa ibyuma bya karubone. Aya masahani akoreshwa cyane mu nyubako zubatswe, gukora mu ruganda, kubaka imashini, no mu bucukuzi. Aya masahani akozwe muri S275JR alloy itandukanye cyane muri kamere.
