S355 pā kila

EN 10025 S355 kila

ʻO ke kila S355 kahi papa kila kila maʻamau o ʻEulopa, e like me EN 10025-2: 2004, ua hoʻokaʻawale ʻia nā mea S355 i 4 mau māka koʻikoʻi:

• S355JR (1.0045),
• S355J0 (1.0553),
• S355J2 (1.0577) a
• S355K2 (1.0596).

ʻOi aku ka maikaʻi o nā waiwai o ke kila S355 ma mua o ke kila S235 a me S275 i ka ikaika a me ka ikaika tensile.

ʻAno kila S355

ʻO nā leka a me nā helu e wehewehe nei i ke ʻano o ka pae kila S355.

• He pōkole ʻo "S" no ka "mea kila kila"
• ʻO ka "355" e pili ana i ka waiwai liʻiliʻi o ka ikaika no ka mānoanoa kila palahalaha a lōʻihi ≤ 16mm.
• “JR” ʻo ia ka liʻiliʻi loa o ka waiwai ikehu hopena ma 27 J ma ka wela lumi (20 ℃).
• Hiki iā "J0" ke pale i ka ikehu hopena ma kahi o 27 J ma 0 ℃.
• ʻO "J2" pili i ka waiwai ikehu hopena liʻiliʻi he 27 J ma -20 ℃.
• "K2" pili i ka li'ili'i loa o ka ikehu waiwai he 40 J ma -20 ℃.

Pepa ʻikepili a me nā kikoʻī

Aia ma lalo nā papa e hōʻike i ka ʻikepili helu kila S355 e pili ana i ka haku mele, ka ikaika hua, ka ikaika tensile a me ka elongation, a me nā mea ʻē aʻe.

Hoʻohui Kimia

Hōʻike ka ʻikepili ma lalo nei i ka pae S355 kila kila hoʻohui.

Na Waiwai Mechanical

Hāʻawi ka ʻikepili ma lalo nei i ka EN 10025 S355 mea kila kila e like me ka hoʻoulu ʻana i ka ikaika, ka ikaika tensile a me ka elongation.
