ʻO ka pā kila ASTM A514 Grade T

Hoʻohana pinepine ʻia ʻo ASTM A514 e like me ke kila hoʻolālā i nā cranes a me nā mīkini kaumaha nui.

ʻO A514 kekahi ʻano kila ikaika kiʻekiʻe, kahi i hoʻopau ʻia a hoʻoheheʻe ʻia ke kila kila, me ka ikaika o ka 100,000 psi (100 ksi a i ʻole 700 MPa). ʻO ka inoa kālepa ArcelorMittal ʻo T-1. Hoʻohana nui ʻia ʻo A514 ma ke ʻano he kila kila no ke kūkulu hale. ʻO A517 kahi huila pili pili i hoʻohana ʻia no ka hana ʻana i nā moku kaomi ikaika.

He maʻamau kēia i hoʻonohonoho ʻia e ka hui maʻamau ʻo ASTM International, he hui hoʻomohala hana maʻamau i hoʻonohonoho i nā kūlana ʻenehana no nā mea waiwai, nā huahana, nā ʻōnaehana, a me nā lawelawe.

A514
Ua kuhikuhi ʻia ka ikaika tensile yield o A514 alloys ma kahi o 100 ksi (689 MPa) no ka mānoanoa a hiki i 2.5 iniha (63.5 mm) pā mānoanoa, a ma ka liʻiliʻi he 110 ksi (758 MPa) ka ikaika tensile hope loa, me ka laulā hope loa o 110–130 ksi (758–896 MPa). ʻO nā pā mai 2.5 a 6.0 iniha (63.5 a 152.4 mm) mānoanoa i hōʻike ʻia i ka ikaika o 90 ksi (621 MPa) (hua) a me 100–130 ksi (689–896 MPa) (hope loa).

A517
A517 kila i like tensile hua ikaika, akā, 'oi aʻe iki ka ikaika hope o 115–135 ksi (793–931 MPa) no ka mānoanoa a hiki i 2.5 'īniha (63.5 mm) a me 105–135 ksi (724–931 MPa) no ka mānoanoa 2.5 a 6.0 iniha (63.5 a 152.4 mm).

Hoʻohana
Hoʻohana ʻia nā kila A514 kahi e pono ai ke kila weldable, machinable, kiʻekiʻe loa e mālama i ke kaumaha a i ʻole e hoʻokō i nā koi ikaika loa. Hoʻohana maʻamau ia ma ke ʻano he kila kila i ke kūkulu hale, nā pahu, a i ʻole nā ​​mīkini nui ʻē aʻe e kākoʻo ana i nā ukana kiʻekiʻe.

Eia kekahi, ua kuhikuhi ʻia nā kila A514 e nā kūlana koa (ETL 18-11) no ka hoʻohana ʻana e like me nā pahu kī kī liʻiliʻi a me nā papa deflector.

Waiwai mīkini no ke kila kila A514GrT:

Hoʻohui kemika no ke kila kila A514GrT (Heat Analysis Max%)

Koi ʻenehana a me nā lawelawe hou aku:

• ʻO ka hoʻāʻo kiʻekiʻe
• Haʻahaʻa wela hopena hoao
• ʻO ka hoʻomaʻamaʻa ʻana i ka wela ma hope o ka welded (PWHT)
• Hāʻawi ʻia ka palapala hōʻike hoʻāʻo ʻo Oginal Mill ma lalo o EN 10204 FORMAT 3.1/3.2
• Ke kuhikuhi ʻia ke kila cooper no A709 Gr36, ʻo ka ʻike Cu≥0.20%
• ʻO ka pana ʻana a me ka pena ʻana, ka ʻoki ʻana a me ka wili e like me nā koi o ka mea hoʻohana hope
• Loaʻa nā mānoanoa kaumaha (3-iniha a ʻoi aku paha) ma ka hapa nui o nā kikowaena hoʻolaha ʻo Leeco Steel.
• Loaʻa i nā māka maʻamau: 36, 50 a me 50W.
• Loaʻa i nā māka hana kiʻekiʻe: HPS 50W a me HPS 70W.
• Hiki i nā mea kūʻai ke kuhikuhi i nā māka A709 e hoʻokō i nā koi hoʻāʻo Charpy no nā wahi kikoʻī a me ke aniau.
