Papa kila kūkulu S355

Wehewehe Pōkole:

Inoa: Papa kila kūkulu S355

ʻO ke kila S355 he kila manganese kalapona haʻahaʻa waena i hiki ke hoʻoheheʻe ʻia a loaʻa iā ia ke kūpaʻa maikaʻi i ka hopena (a i nā mahana ma lalo o ka zero).

ʻO ke kila EN 10025 S355 kahi papa kila kūkulu maʻamau ʻEulopa, e like me EN 10025-2: 2004, ua māhele ʻia ka mea S355 i 4 mau papa maikaʻi nui:
● S355JR (1.0045)
● S355J0 (1.0553)
● S355J2 (1.0577)
● S355K2 (1.0596)
ʻOi aku ka maikaʻi o nā waiwai o ke kila kūkulu S355 ma mua o ke kila S235 a me S275 ma ka ikaika hua a me ka ikaika tensile.

Ka Manaʻo o ka Papa Kila S355 (Ka Hoʻonohonoho ʻana)

Hōʻike nā leka a me nā helu ma lalo nei i ka manaʻo o ke kila kila S355.
ʻO "S" ka pōkole no "kila kūkulu".
ʻO "355" e pili ana i ka waiwai ikaika hoʻohua liʻiliʻi loa no ka mānoanoa kila pālahalaha a lōʻihi ≤ 16mm.
ʻO ke ʻano o "JR" ʻo ka waiwai ikehu hopena he 27 J ka liʻiliʻi loa ma ka mahana o ka lumi (20 ℃).
Hiki i ka "J0" ke kū i ka ikehu hopena ma ka liʻiliʻi he 27 J ma 0℃.
ʻO "J2" e pili ana i ka waiwai ikehu hopena liʻiliʻi loa he 27 J ma -20 ℃.
ʻO "K2" e pili ana i ka waiwai ikehu hopena liʻiliʻi loa he 40 J ma -20 ℃.

ʻO ka haku mele kemika a me ka waiwai mechanical
