ʻIke paha ʻoe i ka mea ʻoi aku ka maikaʻi, ʻo ka pā kila maʻamau ʻAmelika A36 a i ʻole Q235B?

Hoʻokumu ʻo Shandong Kungang Metal Technology Co., Ltd. i ka hana ʻana a me ke kūʻai ʻana i nā pā kila, a loaʻa iā mākou ka ʻike waiwai a me ka kaulana i ka mākeke. Ke kūʻai ʻana i nā pā kila, he mea maʻamau ka lohe ʻana i ka hoʻohālikelike ʻana ma waena o nā pā kila maʻamau ʻAmelika A36 a me Q235B. ʻO kēia mau ʻano papa kila ʻelua kekahi mau ʻokoʻa i ka hana. E hāʻawi mākou iā ʻoe i nā wehewehe kikoʻī o kā lākou hana mai nā hiʻohiʻona he nui a kōkua iā ʻoe e hoʻoholo i nā hoʻoholo kūʻai. ʻO ka mea mua, e hoʻohālikelike kākou i kēia mau papa kila ʻelua ma ke ʻano o ka ikaika. ʻO ka ikaika o ka hoʻoulu ʻana o ka pā kila maʻamau ʻAmelika A36 he 250MPa, a ʻo ka ikaika tensile he 400-550MPa, ʻoiai ʻo ka ikaika hua o ka pā kila Q235B he 235MPa, a ʻo ka ikaika tensile he 375-500MPa. Mai kēia mauʻikepili, hiki keʻikeʻia heʻoi aku ka kiʻekiʻe o ka ikaika o ka pā kila maʻamau oʻAmelika A36 ma mua o Q235B, kahi i kūpono ai no ka hoʻohanaʻana i nā papahana e koi ana i ke kākoʻo ikaika kiʻekiʻe.

ʻO ka lua, e hoʻohālikelike kākou i kā lākou haku mele. ʻO ka hui kemika o ka pā kila maʻamau o ʻAmelika A36 he carbon (C) maʻiʻo o 0.25%, sulfur (S) maʻiʻo o 0.05%, a me phosphorus (P) maʻiʻo o 0.04%, ʻoiai ʻo Q235B ka pā kila he kalapona (C) maʻiʻo o 0.22 %, kakaikahi (S) maʻiʻo o 0.05%, a me ka phosphorus (P) maʻiʻo o 0.045%. Mai ka hiʻohiʻona o ka haku mele ʻana, ʻaʻohe ʻokoʻa nui ma waena o kēia mau ʻano ʻelua o nā papa kila, ʻo ia mau mea ʻelua i ke kalapona kuleana structural steel a he maikaʻi ka weldability a me ka machinability.

Eia kekahi, aia kekahi mau ʻokoʻa i ka pale ʻana i ka corrosion ma waena o nā papa kila maʻamau ʻAmelika A36 a me 0235B. Ma muli o ke kiʻekiʻe o ke kalapona maʻamau o ka pā kila maʻamau ʻAmelika A36, hiki ke ʻino i nā wahi me ka haʻahaʻa kiʻekiʻe. ʻO ka pā kila Q235B maikaʻi ke kūpaʻa corrosion i nā kaiapuni maʻamau. No nā hana ʻenekinia maʻamau, ke koho ʻana i ka pā kila Q235B hiki ke pale maikaʻi i ka hale mai ka ʻino. Ma hope o kēlā, pono mākou e noʻonoʻo i ke kumu o ka weldability. ʻO ka pāpale kila maʻamau o ʻAmelika A36 he weldability maikaʻi a hiki ke hoʻopili ʻia me ka hoʻohana ʻana i nā ʻano hana kuʻuna maʻamau. Eia nō naʻe, loaʻa i ka pā kila Q235B kekahi mau pilikia wili ma muli o kāna ʻike kalapona haʻahaʻa. I kekahi mau papahana e koi ana i ka maikaʻi kuʻihao kiʻekiʻe, ʻoi aku ka hilinaʻi o ke koho ʻana i ka pā kila maʻamau ʻAmelika A36. Ma keʻano holoʻokoʻa, aia kekahi mau ʻokoʻa ma waena o nā papa kila maʻamau ʻAmelika A36 a me Q235B ma ke ʻano o ka ikaika, ka hoʻohui kemika, ke kūpaʻa corrosion, a me ka coalability. Inā makemake ʻoe i ke kākoʻo ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion, hiki iā ʻoe ke koho i ka pā kila maʻamau ʻAmelika A36. Inā loaʻa iā ʻoe nā koi kiʻekiʻe no ka maikaʻi wili, hiki iā ʻoe ke koho i ka pā kila Q235B.

Hāʻawi ʻo Shandong Kungang Metal Technology Co., Ltd. i nā huahana pā kila kiʻekiʻe. Welina mai e nīnau a kipa i kā mākou pūnaewele no ka ʻike hou aku. Manaʻolana mākou e hana pū

a hana i ka nani!
