ʻO ke kila kila haʻahaʻa ikaika kiʻekiʻe (HSLA) kahi ʻano o ke kila kila e hāʻawi ana i nā waiwai mechanical ʻoi aku ka maikaʻi a i ʻole ke kūʻē ʻana i ka corrosion ma mua o ke kila kalapona.Hāʻawi ka ikaika kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa (HSLA) i ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion a ʻoi aku ka ikaika ma mua o ke kila kalapona.He ductile loa ka HSLA, maʻalahi ke wili, a hiki ke hana.ʻAʻole hana maʻamau ʻia nā kila HSLA no ka hoʻokō ʻana i kahi hui kemika kikoʻī akā ua ʻike ʻia lākou e hālāwai me nā waiwai mechanical pololei.Hiki i nā papa HSLA ke hoʻohaʻahaʻa i kāu kumukūʻai waiwai a hoʻonui i nā uku mai ka loaʻa ʻana o ka mea māmā i ka ikaika e pono ai.ʻO nā noi maʻamau no nā papa HSLA e pili ana i nā kaʻa kaʻaahi, nā kaʻa, nā kaʻaahi, nā pahu, nā mea ʻeli, nā hale, a me nā alahaka a me nā lālā hoʻolālā, kahi mea nui e mālama ai i ke kaumaha a me ka lōʻihi.
ʻO 16 mn ka papa kila nui o ka ikaika kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa i ka nui o nā ʻoihana, ʻo ka ʻai ʻana o kēia ʻano he nui loa.ʻOi aku ka kiʻekiʻe o kona ikaika ma mua o ke kila kila Q235 maʻamau e 20% ~ 30%, ke kū ʻana o ka corrosion e 20% ~ 38%.
Hoʻohana nui ʻia ʻo 15 MNVN e like me ka pā kila ikaika.Hōʻike ʻia me ka ikaika kiʻekiʻe a me ka paʻakikī, ka weldability maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a hoʻohana nui ʻia i ka hana ʻana o Bridges, boilers, moku a me nā hale nui ʻē aʻe.
ʻO ka pae ikaika ma luna o 500 Mpa, ʻaʻole hiki ke hoʻokō ʻia ka pā hao hao haʻahaʻa haʻahaʻa i nā koi, ua hoʻomohala ʻia ka pā kila bainite haʻahaʻa.Hoʻohuiʻia me nā mea e like me Cr, Mo, Mn, B, e kōkua i ka pā kila i ka hoʻokumuʻana i ka hui bainite, hana ia me ka ikaika kiʻekiʻe, ka plasticity a me ka hana kuʻihao maikaʻi, ua hoʻohana nuiʻia i ka paila kiʻekiʻe, ka ipu kaomi, etc. hoʻohana nuiʻia no ke kūkuluʻana i nā alahaka, nā moku, nā kaʻa, ka paila, ka moku kaomi, nā paipu aila, ka hale kila nui.
