A36 pā kilaʻo ia kekahi o nā kila maʻamau, ua ʻike paha ʻoe e pili ana iā ia?
E hahai mai iaʻu ma kahi huakaʻi ʻike e pili ana i ke kila A36!
ʻO ka pā kila ASTM-A36 he kila kila maʻamau ʻAmelika i hana ʻia e like me nā kūlana ASTM.ʻO A36 carbon steel coil chemical composition a me nā waiwai mechanical e pili ana i nā kūlana ʻAmelika ASTM.Hoʻohana ʻia ka ʻōwili wela e like me ke kūlana hoʻopuka kumu, a ʻo ka mānoanoa hana ma waena o 2mm a me 400mm.Hiki i nā koi ʻenehana o nā papa kila ke kuhikuhi i ka maʻamau ʻike flaw A578 ʻAmelika.ʻEkolu pae ʻike kīnā ʻole A, B, C a me A435 pae ʻike hala.A36 wela olokaa kila hana mea paa no ka hana.ʻO ka pā kila wela A36 i loaʻa nā waiwai mechanical maikaʻi, ka hana kuʻi ʻana a me ka pale ʻana i ka corrosion, a hoʻohana nui ʻia i ke kūkulu ʻana, nā alahaka, nā mīkini hana a me nā māla ʻē aʻe.
ʻO ASTM-A36 kahi ʻano o ke kila kalapona nona ka haku mele i haku ʻia me carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) a me nā mea ʻē aʻe.Ma waena o lākou,ʻo ka carbon ka mea nui, aʻo kāna hana e hoʻonui i ka ikaika a me ka paʻakikī o ke kila.ʻO ka silikoni a me ka manganese nā mea hoʻohui e hoʻonui i ka ikaika a me ka paʻakikī o ke kila.ʻO ka phosphorus a me ka sulfur nā mea haumia.ʻO ko lākou hele ʻana e hōʻemi i ka paʻakikī a me ke kūpaʻa corrosion o ke kila, no laila pono e mālama pono ʻia kā lākou ʻike i ka wā o ke kaʻina hana.
C:≤0.25%
ʻO: ≤0.4%
Mn:≤0.8-1.2%
P：≤0.04%
S：≤0.05%
Cu：≤0.2%
Loaʻa iā ASTM-A36 nā waiwai mechanical maikaʻi loa, me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka plasticity maikaʻi a me nā waiwai hoʻoili.ʻO kona ikaika tensile he 160ksi (1150MPa), he 145ksi (1050MPa), ka elongation he 22% (2-inch gauge), a he 45% ka emi ʻana o ka pauku.Hāʻawi kēia mau mea mīkini i ka ASTM-A36 kiʻekiʻe i ka haʻahaʻa haʻahaʻa a me ke kūpaʻa seismic i nā noi ʻenekinia like ʻole.
Ka ikaika hana——≥360MPa
Ka ikaika tensile——400MPa-550MPa
Elongation ma hope o ka hoomaha——≥20%
ʻO ke kaʻina hana o ka pā kila A36 ka nui o ka hoʻolei ʻana, ka ʻōwili wela, ka ʻōwili anu, ka annealing a me nā kaʻina hana ʻē aʻe.ʻO ka mea mua, hoʻoheheʻe ʻia nā mea maka i loko o nā billet kila i nā wela kiʻekiʻe, a laila hoʻolei mau ʻia e kiʻi i nā ingots kila.A laila,'ōwili wela a'ōwiliʻia ke anuanu no ka loaʻaʻana o ka pā kila me nā kiko'ī i makemakeʻia.ʻO ka mea hope loa, ua hoʻopili ʻia ka pā kila e hoʻopau i ke koʻikoʻi o loko a hoʻomaikaʻi i nā waiwai mechanical a me ke kūpaʻa o ka pā kila.Eia kekahi, no ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ʻili a me ka pololei o ka pā kila, pono nā kaʻina hana e like me ka palahalaha, pololei, a me ka ʻoki pololei.
Hoʻohana nui ʻia nā papa kila ASTM-A36 i nā ʻano ʻenekinia like ʻole, e like me ke kūkulu ʻana, nā alahaka, nā mīkini hana, etc.
Ma ke kahua kūkulu, hoʻohana ʻia nā papa kila ASTM-A36 e hana i nā ʻano hale like ʻole, e like me nā hale noho, nā hale keʻena, nā hale kūʻai kūʻai, etc.
Ma ke kahua o nā alahaka, hoʻohana ʻia nā papa kila ASTM-A36 e hana i nā hale alahaka nui, e like me nā alahaka ala, nā alahaka alahao, etc.
Ma ke kahua o ka mīkini hana, hoʻohana ʻia nā papa kila ASTM-A36 no ka hana ʻana i nā ʻāpana hana mechanical, e like me nā excavators, cranes, nā mīkini mahiʻai, etc.
Me ka hoʻomohala ʻana o ka hoʻokele waiwai a me ka wikiwiki o ka urbanization, e hoʻomau ka piʻi ʻana o ka noi no nā papa kila A36 i ke kūkulu ʻana, nā alahaka a me nā māla ʻē aʻe.I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ka ʻike kaiapuni, e ʻoi aku ka laulā o ka mākeke o nā papa kila ASTM-A36.Ma nā kahua e like me nā kaʻa ikehu hou a me ka hoʻoulu ʻana i ka makani, e hoʻomau ʻia ka koi no nā papa kila ASTM-A36.Eia kekahi, i ka hoʻomau ʻana o ka ʻāina i ka hoʻopukapuka ʻana i ke kūkulu ʻana i nā ʻoihana, e hoʻomau ka nui o ka koi no nā papa kila ASTM-A36 i ke kūkulu ʻana, nā alahaka a me nā māla ʻē aʻe.No laila, ʻo ka pā kila ASTM-A36 he mau mākeke ākea ākea a me ka waiwai hoʻopukapuka kiʻekiʻe.
ʻO ka pā kila A36 he mea hoʻohana nui ʻia ka carbon structural steel plate me nā waiwai mechanical maikaʻi loa, ka hana kuʻi ʻana a me ka pale ʻana i ka corrosion.
Hoʻopili ʻia kāna mau kahua noi i ke kūkulu ʻana, nā alahaka, nā mīkini hana a me nā ʻano ʻē aʻe.
I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ka ʻike kaiapuni a me ka hoʻomohala ʻana o nā kaʻa ikehu hou, ka makani makani a me nā māla ʻē aʻe, e ʻoi aku ka laulā o ka mākeke o nā papa kila ASTM-A36.
No laila, no ka poʻe hoʻopukapuka kālā, loaʻa iā ASTM-A36 kahi waiwai hoʻopukapuka kiʻekiʻe.
I ka manawa like, no nā mea hoʻolālā hoʻolālā a me nā mea hana, ʻo ASTM-A36 kekahi mea waiwai kiʻekiʻe e koho ai.
Manaʻo wau he mea kōkua kēia ʻatikala iā ʻoe.
Inā makemake ʻoe e ʻike i nā ʻepekema kaulana ʻē aʻe, e ʻoluʻolu e nānā i kēia pūnaewele.
Ka manawa hoʻouna: Dec-11-2023
