Ipleyiti yeS355 yeStructural Steel

Inkcazelo emfutshane:

Igama: Ipleyiti yeS355 yeStructural Steel

Intsimbi yodidi lwe-S355 yintsimbi ephakathi, ephantsi yekhabhoni yemanganese ekwazi ukuwelda ngokulula kwaye inoxhathiso olululo lwempembelelo (kwakhona kumaqondo obushushu angaphantsi kweqanda).

Iinkcukacha zajikelele

I-EN 10025 i-S355 intsimbi yinqanaba laseYurophu lolwakhiwo lwentsimbi, ngokwe-EN 10025-2: 2004, imathiriyeli ye-S355 yahlulwe yangamanqaku ama-4 asemgangathweni:
● S355JR (1.0045)
● S355J0 (1.0553)
● S355J2 (1.0577)
● S355K2 (1.0596)
Iimpawu zentsimbi yesakhiwo S355 ingcono kunentsimbi ye-S235 kunye ne-S275 kumandla okuvelisa kunye namandla okuqina.

Steel Grade S355 Intsingiselo (uLuhlu)

Oonobumba kunye namanani alandelayo achaza i-steel grade S355 intsingiselo.
"S" lifutshane elithi "structural steel".
"355" ibhekiselele kwixabiso leminumum yesivuno samandla esisicaba kunye nobude bentsimbi ≤ 16mm.
"JR" ithetha ixabiso lamandla empembelelo yi-minumum 27 J kwiqondo lobushushu begumbi (20℃).
"J0" inokumelana namandla empembelelo ubuncinane kwi-27 J kwi-0℃.
"J2" enxulumene nexabiso le-minumum yempembelelo yamandla yi-27 J ku -20 ℃.
"I-K2" ibhekisa kwixabiso le-minumum lempembelelo yamandla yi-40 J ku -20℃.
