1. He aha ka papa kila ASTM A709?
He papa kila ikaika kiʻekiʻe ʻo ASTM A709, he haʻahaʻa-alloy ka mea i hoʻohana nui ʻia i nā alahaka, nā kūkulu kaumaha, a me nā papahana ʻoihana. Hāʻawi ia i ka paʻakikī maikaʻi loa, ka hiki ke hoʻopili ʻia, a me ke kūpaʻa i nā wahi waho a me nā wahi kaumaha kiʻekiʻe.
2. Hiki ke hoʻopili ʻia ke kila ASTM A709?
ʻAe. Hiki ke hoʻoheheʻe ʻia nā papa āpau, akā pono paha ka hoʻomehana mua kūpono a me ka mālama ʻana ma hope o ka hoʻoheheʻe ʻana no nā papa mānoanoa a i ʻole nā wahi haʻahaʻa. Pono nā papa ʻino i ka hoʻoheheʻe akahele e mālama i ke kūpaʻa ʻana i ka pala.
3. He aha nā nui a me nā mānoanoa e loaʻa ana?
Mānoanoa o ka pā: ʻO ka maʻamau 6 mm - 250 mm
Laulā: A hiki i ka 4,000 mm ma muli o ka mea hana
Lōʻihi: ʻO ka maʻamau he 12,000 mm, akā hiki ke hoʻopilikino ʻia
4. He aha ka ʻokoʻa ma waena o ASTM A709 a me ASTM A36?
ʻOi aku ka ikaika o ka ASTM A709, ʻoi aku ka paʻakikī, a me nā waiwai koho no ka pale ʻana i ka wā.
He kila kalapona maʻamau ka ASTM A36, ʻo ia hoʻi no nā noi kūkulu maʻamau, ʻaʻole i hoʻonohonoho pono ʻia no nā alahaka a i ʻole nā wahi ʻino.
5. Pehea e hoʻāʻo ʻia ai ka papa kila ASTM A709?
Nā hoʻāʻo tensile e hōʻoia i ka hua a me ka ikaika hope loa
Nā hoʻāʻo hopena Charpy no ka paʻakikī i nā mahana haʻahaʻa
Ka loiloi kemika e hōʻoia i ka haku mele ʻana o ka metala
Nā nānā pālahalaha a me nā ana
6. No ke aha e koho ai i ka papa kila ASTM A709?
Ikaika kiʻekiʻe no ke kaumaha i hoʻemi ʻia
Hana maikaʻi loa i ka weldability a me ka hana hana
Nā papa hoʻomalu ʻino koho no ka lōʻihi o ka manawa
Kūpono no nā wahi haʻahaʻa a me ke kaumaha kiʻekiʻe
