Nūhou - ASTM A992 vs A572 vs A283 vs A913: Nā ʻokoʻa koʻikoʻi ma nā papa kila kūkulu

I kēia lā, ʻo ke koho ʻana i ke kūlana kūpono o ke kila he mea nui ia no ka pono o ke kūkulu ʻana, ka hana ʻana, a me ke kumukūʻai holoʻokoʻa o ka papahana ma ka ʻoihana kūkulu hale. Ma lalo o nā kūlana ʻAmelika, aia nā ʻano maʻamau ʻehā okila kūkulu ASTM A992, A572, A283 a me A913He ʻokoʻa nā pae hana a me nā koi papahana o kēlā me kēia kila.

hui aliʻi o ke kūkulu ʻana i nā hale kila (2)

Nā ʻokoʻa o nā mea a me nā mīkini

ASTM A992
Māhele: Kila hoʻonohonoho haʻahaʻa ikaika kiʻekiʻe (HSLA)
Ka palena iki o ke kaumaha: 345 MPa (50 ksi) ka ikaika hua
ʻAno: Hoʻomalu paʻa ʻia ka haku mele ʻana o ka "mea hana wili a me nā mea hoʻopau wili e pili ana i ke kaumaha" e hōʻoia i ke kūlike a me ka paʻakikī.
ʻAno Nui: Hana kūikawā ʻia no ka flange ākea o ka ʻōwili wela (kaula W/H).
ʻO A992 ke kila ikaika kiʻekiʻe maʻamau ma ʻAmelika ʻĀkau no ke kūkulu ʻana i ke kila kila.

ASTM A572
Māhele: Kila hoʻonohonoho haʻahaʻa ikaika kiʻekiʻe (HSLA)
Nā Māka: 42, 50, 55, 60, 65
Pae o ka ikaika: ʻOi aku ma mua o ke kila kalapona maʻamau.
Hoʻolako: Nā papa, nā kihi, nā kahawai, nā kaola a me nā mea hou aku
Hiki ke hoʻopili ʻia nā papa haʻahaʻa (Papa 42,50) me nā kaʻina hana hoʻopili maʻamau, pono nā papa kiʻekiʻe (Papa 65) i nā kaʻina hana hoʻopili kūikawā a i ʻole ka hoʻokolokolo hou ʻana e like me PWHT etc.

ASTM A283
ʻAno: Ke kila kūkulu kalapona (kila palupalu)
Nā Māka: ABCD = Loaʻa
Ikaika: ʻOi aku ka nāwaliwali ma mua o A572 a me A992
Hiki iā ʻoe ke ʻōlelo ua like ia me ke kūkulu ʻana a me ka hoʻoheheʻe ʻana i kahi ʻelepani pēpē no ke kumukūʻai o kahi ʻelepani makua.
ʻO ka hana māmā wale nō a i ʻole. ʻO ka ASTM A283 General ka mea i manaʻo ʻia no ka hoʻohana ʻana me nā ʻano hana koʻikoʻi ʻole.

ASTM A913
ʻAno: Ke kila kila haʻahaʻa ikaika kiʻekiʻe ma ke ʻano QST (quenching a me ka hoʻomaʻamaʻa ponoʻī)
Nā Māka: 50, 65, 70 = Loaʻa
Hiʻona: Ikaika nui, paʻakikī koʻikoʻi a me ka hiki ke hoʻopili maikaʻi ʻia i loko o ke kila ikaika kiʻekiʻe loa.
ʻAno Nui no nā kaola flange ākea mānoanoa a kaumaha
Hoʻohana nui ʻia ka A913 ma nā wahi e pono ai ka ikaika kiʻekiʻe a me nā ʻāpana lahilahi i nā hale kila nui a kiʻekiʻe.

Nā ʻokoʻa noi

ASTM A992
Nā hale kila kalepa a me nā hale
Nā kiʻi no nā hale kiʻekiʻe a me nā hale waena
Nā hale ʻoihana a me nā hale hoʻolaha
Kumu: Hiki ke hilinaʻi pono ʻia a maʻalahi hoʻi ke kuʻi ʻia, hoʻohana ʻia ma ke kino o ke kaʻa.

ASTM A572
Nā Alahaka
Nā Hale Hana
Nā hale kiaʻi a me nā hale ikehu
Nā kahua kaumaha
Kumu: Hiki i nā ʻenekinia hoʻolālā ke hoʻonui i ke kaulike ma waena o ka ikaika a me ke kumukūʻai me nā māka he nui.

ASTM A283
Nā hale haʻahaʻa
Nā hale hana kila māmā a me nā hale hana
Nā mahiʻai a me nā hale hana manawa pōkole
Nā ʻāpana koʻikoʻi ʻole
Kumu: He mea maʻalahi ke mālama ʻana i nā mea, akā me ka liʻiliʻi o ka hiki ke hāpai.

ASTM A913
Nā Hale Kiʻekiʻe
Nā alahaka lōʻihi
Nā kahua pāʻani a me nā hale kūʻai
Nā papahana ʻoihana kaumaha
Kumu: Hiki ke hoʻokō ʻia nā lālā lahilahi a me nā ʻā lōʻihi me ka ikaika kiʻekiʻe loa.

Makemake Mākeke a me ka ʻĀpana

ʻAno kila ASTM A992Loaʻa ma ʻAmelika Hui Pū ʻIa a me Kanada, Hikina Waena, Hikina Hema ʻAsia no ke Kiʻikuhi Hale.

ʻAno kila ASTM A572Makemake ʻia ma ka Honua o ʻAmelika a me nā ʻĀpana i Kuhikuhi ʻia i ke ʻano hana e like me nā Alahaka a me nā Hale Kaumaha.

ʻAno kila ASTM A283Hoʻohana nui ʻia ma nā ʻāina ʻē aʻe o ka honua no ke kūkulu ʻana me ka hoʻokele waiwai a me ka māmā.

ʻAno kila ASTM A913Hoʻohana nui ʻia ma nā ʻāina i hoʻomohala ʻia a me ka ʻāpana papahana mega e like me USA, ʻEulopa, Hikina Waena, ʻAsia Hikina.

Nā Manaʻo Kumukūʻai a me ka Hoʻokele Waiwai

A283: Kumukūʻai haʻahaʻa a me ke ʻano haʻahaʻa

A992: Kūpono ke kumukūʻai, kaulike maikaʻi o ka ikaika a me ka maʻalahi o ka hana ʻana

A572: Pili ke kumukūʻai i ka papa

A913ʻO ke kumukūʻai kiʻekiʻe loa no kēlā me kēia ʻāpana, akā ʻo ka ikaika kiʻekiʻe e hōʻemi ana i ka nui o ke kila

Hiki i nā kila ikaika kiʻekiʻe ke hōʻemi i nā kumukūʻai papahana holoʻokoʻa ma ka hōʻemi ʻana i nā mea hana, ka halihali a me ka nui o ke kau ʻana.

Hana ʻana a me ka Kuʻihao

A283: Maʻalahi e ʻoki a hoʻopili

A992: Hana ʻia e hoʻopaʻa ʻia no ke kūkulu ʻana

A572Hiki ke hoʻoheheʻe ʻia, akā koi ʻia ka mana paʻa no nā pae kiʻekiʻe

A913He ʻano hana hou e ʻae ai i ka hiki ke hoʻopili maikaʻi ma nā pae ikaika kiʻekiʻe loa.

ʻO ASTM A283, A992, A572 a me A913 he ʻehā mau papa hana no ke kila kūkulu. No ka hoʻokele waiwai ʻo A283, ʻo A992 ke kiʻikuhi hale maʻamau, hāʻawi ʻo A572 i nā koho ikaika like ʻole no nā ʻoihana kūkulu a ʻo A913 ka waiwai maikaʻi loa no nā noi kūkulu kaumaha a kiʻekiʻe. Ke hoʻoulu nei nā papahana kūkulu ikaika i ka neʻe ʻana i nā kila kūkulu ikaika kiʻekiʻe ma ka mākeke honua.
