ʻO ka manaʻo kumu a me ka hoʻohana ʻana o ke kila structural carbon

ʻO ka mea mua, ʻo ka manaʻo kumu a me ka hoʻohana ʻana o ke kila structural carbon
ʻO ke kila structural carbon e pili ana i nā mea kila me ka ʻona kalapona ʻaʻole i ʻoi aku ma mua o 2.11%, i hoʻohana nui ʻia i ka hana ʻana, ke kūkulu ʻana, ka metallurgy, ka hana moku, ka hana mīkini, ka ʻaila a me nā ʻoihana kemika.Loaʻa iā ia ka plasticity maikaʻi, weldability a me ka machinability, a he haʻahaʻa ke kumukūʻai, me ka hana kiʻekiʻe.
ʻElua, he nui nā ʻano kila i hoʻohana mau ʻia i ke kila hana kalapona
1. Q235 kila: He mea maʻamau i hoʻohana ʻia ke kila kalapona haʻahaʻa, hoʻohana nui ʻia i ka hoʻolālā ʻenekinia maʻamau a me ka hana mechanical.Loaʻa iā ia nā pōmaikaʻi o ka ikaika maikaʻi, ka ductility maikaʻi a me ke kumu kūʻai haʻahaʻa, a hoʻohana nui ʻia i nā Bridges, nā hale, nā moku a me nā māla ʻē aʻe.
2. Q345 kila: He mea waena a me ka ikaika kiʻekiʻe haʻahaʻa kila kila, i hoʻohana nui ʻia.Loaʻa iā ia ka ikaika kiʻekiʻe a me ka ductility ʻoi aku ka maikaʻi ma mua o ke kila Q235, a hoʻohana nui ʻia i nā Bridges, nā moku, nā petrochemical a me nā kahua kūkulu.
3. 20 # kila: He mea maʻamau ka hoʻohana ʻana i ke kila kila a hoʻohana nui ʻia.Loaʻa iā ia nā mea maikaʻi o ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ke kūpaʻa maikaʻi ʻana, a me nā mea ʻē aʻe, a hoʻohana nui ʻia i ka hana mīkini, nā ʻāpana kaʻa, nā bearings, nā hāmare a me nā māla ʻē aʻe.
4. 45 # kila: He 'ano o ka holomua kalapona structural kila me ka laulā o nā noi.Loaʻa iā ia nā hiʻohiʻona o ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi o ka lole, a me nā mea ʻē aʻe, a hoʻohana nui ʻia i ka hana ʻana i nā excavators, nā mīkini mīkini, ka transit rail a me nā māla ʻē aʻe.
5. 65Mn kila: ʻO ia ke kila kalapona kalapona, hoʻohana nui ʻia i ka hana ʻana i nā pūnāwai a me nā ʻāpana stamping.Loaʻa iā ia ka elasticity maikaʻi, ke kūpaʻa kūlou a me ke kūpaʻa corrosion, a hoʻohana nui ʻia i nā kaʻa, nā mīkini hana, nā moku a me nā māla ʻē aʻe.
Ma keʻano laulā, hilinaʻi nui ke koho ʻana i ke kila hoʻolālā kalapona i ke kahua noi kikoʻī a me ka hoʻohana ʻana i ke kaiapuni.Ma nā kahua like ʻole a me nā kaiapuni, pono e koho ʻia ka pae kila kūpono e hōʻoia i ka hopena hoʻohana a me ka palekana
