EN 10025 S275 Chitsulo (S275JR, S275J0 & S275J2)
EN 10025 S275 Chitsulo ndi kalasi yachitsulo yopanda aloyi, malinga ndi EN10025, S275 chitsulo chofatsa chimagawidwa makamaka kukhala S275JR (1.0044), S275J0 (1.0143) ndi S275J2 (1.0145). Zina za S275 mild steel ndizabwino kuposa S235, komanso zotsika kuposa S355.
Dzina lachikale la S275 ndi St44 malinga ndi muyezo waku Germany, kalasi yakale yofanana ndi iyi:
EN10025 S275JR (1.0044) - St44-2 mu DIN 17100
S275JO (1.0143) - St44-3U mu DIN17100
S275J2 (1.0145) - S275J2G4 mu EN 10025: 1993
EN10025 S275JR Tanthauzo (Mapangidwe)
Mindandanda ili pansipa ikufotokoza tanthauzo la EN10025 S275JR
"S" ndi chitsulo chokhazikika;
"275" amatanthauza mphamvu zochepa zokolola ndi 275 MPa zoyesedwa ndi makulidwe achitsulo ≤ 16mm.
"JR" amatanthauza kuti mtengo wocheperako wa charpy kutentha ndi 27J.
"J0" imatanthawuza kutsika kocheperako kwa charpy pa 0 °C ndi 27J.
"J2" amatanthauza mtengo wocheperako pa -20 °C ndi 27J.
S275 Data Sheet & Kufotokozera
TS EN 10025 S275 katundu wachitsulo, kapangidwe kake ndi zida zofananira zitha kupezeka pazotsatira zotsatirazi. Mapepala onse a DIN EN 10025-2 ndi ofanana ndi BS EN 10025-2 ndi mayiko ena a EU.

S275JR PLATE ndi mbale yachitsulo yopangidwa kuchokera ku chitsulo chochepa kapena chitsulo cha carbon. Mabala awa akugwiritsidwa ntchito kwambiri pomanga, kupanga mafakitale, kumanga makina, ndi migodi. Ma mbale awa amapangidwa ndi aloyi a S275JR omwe ndi osinthasintha kwambiri m'chilengedwe.

Chemical Composition
Datasheet 1, EN10025 S275J0, S275J2 ndi S275JR kapangidwe ka mankhwala kutengera kusanthula ladle kwaperekedwa mu tebulo ili pansipa.
