Hāʻawi ʻia ka pepa kila ASTM SA283GrC/Z25 i ke kūlana ʻōwili wela SA283GrC Kūlana hāʻawi:
Ke kūlana hoʻouna SA283GrC: Ma ke ʻano laulā, i ke kūlana hoʻouna ʻana i ʻōwili wela ʻia, pono e hōʻike ʻia ke kūlana hoʻouna kikoʻī i loko o ka palapala hoʻokō.
ʻO ka waiwai o ka pae hoʻohuihui kemika SA283GrC: Nānā: ʻO ka hoʻohuihui kemika maoli i loko o ka palapala hoʻokō o ka hale hana kila e lanakila.
Kalapona C: ≤0.24 Si: (papa kila ≤40) ≤0.40 (papa kila > 40) 0.15-0.40
Manganese Mn: ≤0.90 Sulfur S: ≤0.040 Phosphorus P: ≤0.035
Keleawe Cu: 0.20 a emi mai paha
He kūpono ka papa kila SA283GrC no ke kāpili ʻana, ka hoʻopaʻa ʻana i nā ʻōnaehana hoʻopaʻa a me ka hoʻoheheʻe ʻana no nā alahaka a me nā hale. He kila kila kalapona ia no ke kumu maʻamau me ke ʻano kila kila.
Ke kūlana hoʻouna papa kila SA283GrC: ʻōwili wela, ʻōwili i kāohi ʻia, kūlana maʻamau o ka hoʻouna ʻana
Mea hana no ke kūkulu ʻana i ka umu pahū SM400ZL kila kila:
ʻO SM400ZL kahi papa kila ikaika haʻahaʻa haʻahaʻa Kepanī no ka pūpū hoʻololi. Kuhi kēia kūlana i ka nui, ke ʻano, nā koi loea, nā ʻano hoʻāʻo, nā lula nānā, ka hoʻopili ʻana, nā māka a me nā palapala hōʻoia maikaʻi o nā papa kila no ka umu pahū, ka mea hoʻololi a me nā pūpū umu wela. Pili ia i ka papa kila no ka pūpū umu me ka mānoanoa o 8mm ~ 200mm. ʻO ka ʻokoʻa mānoanoa maikaʻi ʻole o ka papa kila SM400ZL ua kaupalena ʻia i -0.25mm, a pono e kūlike ka ʻāpana hoʻomanawanui mānoanoa me GB/T709.
Papa kila S355NL [8-200 mānoanoa] ʻoki ʻana i ka haku mele, papa inoa mea:
ʻO ke kūlana hoʻokō S355NL: EN10025-3: inoa piha: normalizing/normalizing rolled weldable fine grain structural steel plate. Hoʻololi pū kēia kūlana a me EN10025-1 i nā huahana kila kila maikaʻi i hoʻopili ʻia me ka wela i ʻōwili ʻia me ka ʻĀpana I: Nā kūlana laulā a me EN 10113-2:1993 nā huahana kila kila maikaʻi i ʻōwili ʻia me ka wela i ʻōwili ʻia me ka ʻĀpana II: normalizing/normalizing rolling steel conditions. Ke emi ʻole ka mahana o ka papa ma mua o - 20 ° C, ua hōʻike ʻia ka waiwai liʻiliʻi o ka ikehu hopena i kuhikuhi ʻia ma N; ke emi ʻole ka mahana ma mua o - 50 ° C, ua hōʻike ʻia ka waiwai liʻiliʻi o ka ikehu hopena i kuhikuhi ʻia ma NL.
2. ʻO ke ʻano like o ka leka papa kila S355NL:
S: kila kūkulu, N: moku'āina, kapikala L: ke kiʻekiʻe o ka ikehu hopena i kuhikuhi ʻia i ka wā ʻaʻole i emi ka mahana ma mua o - 50 ° C
Papa kila S355ML [8-200mm mānoanoa] ʻōwili thermomechanical
Hāʻawi ʻia ka papa kila S355ML i ke kūlana ʻōwili mīkini thermo
Nā Pono Hoʻohui Kemika S355ML
C：≤0.14，Si：≤0.5，Mn：≤1.6，P：≤0.025，S：≤0.02，Nb：≤0.05，V：≤0.1，A l：≤0.02，Ti：≤0.05，Cr：≤0.3，Ni：≤0.5，Mo：≤0.1，Cu：≤0.55，N：≤0.015.
ʻO ka papa kila S355ML kahi kila kila maikaʻi i hoʻopili ʻia a wela ʻia, no kahi moʻo o nā papa kila ikaika haʻahaʻa haʻahaʻa. He huahana pālahalaha i ʻōwili ʻia me ka mānoanoa ʻaʻole i ʻoi aku ma mua o 120mm a he huahana lōʻihi me ka mānoanoa ʻaʻole i ʻoi aku ma mua o 150mm. ʻO S ke ʻano o ke kila kila, ʻo 355 e hōʻike ana i ka waiwai liʻiliʻi o ka mānoanoa kūpono ma lalo o 16mm he 355MPa, a ʻo M ke ʻano o kāna lawe ʻana, ʻo ia hoʻi, ka ʻōwili wela. ʻO ke kānāwai, ʻo ka hopena ma ka mahana ʻaʻole i emi iho ma mua o - 50 degere e hōʻike ʻia e ka leka nui L. ʻO S355 he kila kila non-alloy.
Ka laulā noi o ka papa kila S355ML
Ma waho aʻe o ke kila EN10,025-1, hoʻohana ʻia ka hoʻolālā kila i kuhikuhi kūikawā ʻia ma kēia kūlana no nā ʻāpana halihali ukana o nā hale i hoʻopili ʻia i hoʻohana ʻia a puni nā alahaka, nā lua wai, nā pahu mālama, nā pahu lako wai, a me nā mea ʻē aʻe a me ka mahana haʻahaʻa.
