ʻO ka ASTM SA283GrC/Z25 Steel Sheet i hāʻawi ʻia ma ke kūlana ʻōwili wela SA283GrC Kūlana hoʻouna:
SA283GrC kūlana hāʻawi: ʻO ka mea maʻamau i ke kūlana wela o ka lawe ʻana, pono e hōʻike ʻia ke kūlana hoʻopuka kikoʻī ma ka palapala hōʻoia.
SA283GrC ka waiwai hoʻohui kemika: Nānā: E lanakila ka haku mele maoli i loko o ka hale hana kila.
Carbon C: ≤0.24 Si: (pā kila ≤40) ≤0.40 (pā kila> 40) 0.15-0.40
Manganese Mn: ≤0.90 Sulfur S: ≤0.040 Phosphorus P: ≤0.035
Copper Cu: 0.20 a emi mai paha
ʻO SA283GrC ka pā kila he kūpono ia no ka riveting, bolting a me ka hoʻopili ʻana i nā hale no nā Alahaka a me nā hale.He mea maʻamau ka hana kalapona kila me ke kila kila maikaʻi.
SA283GrC ke kūlana hāʻawi ʻana i ka pā kila: ka ʻōwili wela, ka ʻōwili ʻia ʻana, ke kūlana maʻamau o ka lawe ʻana
Mea no ke kūkulu ʻana i ka umu ahi SM400ZL pā kila:
ʻO SM400ZL kahi papa kila ikaika kiʻekiʻe ma Iapana no ka pūpū hoʻololi.Hōʻike kēia maʻamau i ka nui, ke ʻano, nā koi ʻenehana, nā ʻano hoʻāʻo, nā lula nānā, ka paʻi, nā hōʻailona a me nā palapala hōʻoia maikaʻi o nā pā kila no ka blast furnace, converter a me nā pūpū wela wela.Ua pili i ka pā kila no ka umu ahi me ka mānoanoa o 8mm ~ 200mm.ʻO ka hoʻokaʻawale ʻana o ka mānoanoa maikaʻi ʻole o ka pā kila SM400ZL i kaupalena ʻia i -0.25mm, a e hoʻokō ka mānoanoa tolerance zone me GB/T709.
S355NL pā kila [8-200 mānoanoa] ʻoki haku mele, papa inoa mea:
S355NL kūlana hoʻokō: EN10025-3: inoa piha: normalizing/normalizing rolled weldable fine grain structural steel plate.Hoʻopili kēia maʻamau a me EN10025-1 i ka EN 10113-1: 1993 wela-rolled weldable fine grain structural steel products Part I: General condition and EN 10113-2:1993 hot-rolled weldable fine grain structural steel products Part II: normalizing/normalizing kūlana kila ʻōwili.Ke emi ka mahana o ka papa ma lalo o - 20 ° C, hōʻike ʻia ka waiwai haʻahaʻa o ka ikehu hopena i kuhikuhi ʻia ma N;ke emi ka mahana ma lalo o - 50 ° C, hōʻike ʻia ka waiwai liʻiliʻi o ka ikehu hopena i kuhikuhi ʻia ma NL.
2. ʻO ka manaʻo kūpono o ka palapala papa kila S355NL:
S: kila kila, N: mokuʻāina, kapikala L: ka pae o ka ikehu hopena i ʻōlelo ʻia inā ʻaʻole emi ka mahana ma mua o - 50 ° C
S355ML pā kila [8-200mm mānoanoa] thermomechanical olokaʻa
Hāʻawi ʻia ka pā kila S355ML i ka mokuʻāina ʻo thermo mechanical rolling state
S355ML Nā Koina Hoʻohui Kimia
C：≤0.14，Si：≤0.5，Mn：≤1.6，P：≤0.025，S：≤0.02，Nb：≤0.05，V：≤0.1，Al：≤0.02，Ti：≤0.05，Cr：≤0.3 Ni：≤0.5，Mo：≤0.1，Cu：≤0.55，N：≤0.015。
ʻO ka pā kila S355ML he kila hoʻoheheʻe maikaʻi ʻia i ka weldable weldable, nona ka pūʻulu o nā papa kila ikaika ikaika.ʻO ia kahi huahana ʻōwili pālahalaha me ka mānoanoa ʻaʻole ʻoi aku ma mua o 120mm a me kahi huahana lōʻihi me ka mānoanoa ʻaʻole ʻoi aku ma mua o 150mm.S 'o ia ho'i ke kila kila, 355 hō'ike 'o ka li'ili'i o ka hua o ka mānoanoa kūpono ma lalo o 16mm he 355MPa, a 'o M e hō'ike ana i kona hā'awi 'ana, 'o ia ho'i, ka'ōwili wela.ʻO ke kānāwai, ʻo ka hopena ma ka mahana ʻaʻole i emi iho ma lalo o - 50 degere i hōʻike ʻia e ka leka nui L. S355 ʻaʻole i hoʻohuihui ʻia ke kila.
Ka laulā noi o ka pā kila S355ML
Ma waho aʻe o ke kila EN10,025-1, hoʻohana ʻia ka hoʻolālā kila i ʻōlelo ʻia i kēia maʻamau no nā ʻāpana ukana o nā hale welded i hoʻohana ʻia a puni nā alahaka, nā sluices, nā pahu mālama, nā pahu wai, a me nā mea ʻē aʻe a me ka haʻahaʻa haʻahaʻa.
