ulwazi oluvamile
I-EN 10025 S355 insimbi iyizinga lensimbi lesakhiwo elijwayelekile laseYurophu, ngokuya nge-EN 10025-2: 2004, impahla ye-S355 ihlukaniswe ngamabanga ama-4 aphezulu:
● I-S355JR (1.0045)
● S355J0 (1.0553)
● S355J2 (1.0577)
● I-S355K2 (1.0596)
Izakhiwo zensimbi yesakhiwo i-S355 ingcono kunensimbi S235 kanye ne-S275 emandleni esivuno namandla aqinile.
Steel Grade S355 Meaning (Ukuqokwa)
Izinhlamvu nezinombolo ezilandelayo zichaza incazelo yezinga lensimbi S355.
Igama elithi "S" lifushane elithi "structural steel".
"355" ibhekisela enanini lamandla esivuno esincane sobukhulu bensimbi obuyisicaba nobude ≤ 16mm.
"JR" isho inani lamandla elinomthelela liyi-minumum 27 J ekamelweni lokushisa (20℃).
I-"J0" ingamelana namandla okuthinta okungenani ama-27 J ku-0℃.
I-"J2" ehlobene nenani lamandla omthelela omncane ngu-27 J ku -20℃.
I-"K2" ibhekisela enanini lamandla omthelela omncane ngu-40 J ku -20℃.
