Hoʻāʻo ʻia ke kila, me nā ʻāpana kila, no ka maikaʻi ma nā ʻano like ʻole, e like me ka hoʻāʻo ʻana i ka tensile, ka hoʻāʻo ʻana i ka luhi, ka hoʻāʻo ʻana a me ka hoʻāʻo ʻana i ka corrosion resistance.Hiki ke hoʻomohala a hana ʻia nā mea hana a me nā huahana pili i ka manawa maoli e mālama i ka hana maikaʻi o ka huahana, hiki ke pale i ka hoʻihoʻi ʻana ma muli o ka maikaʻi a me ka pau ʻole o nā mea maka.
Nui nā ʻano kila maʻamau.
ʻO ka hao hao
ʻO ke kila kalapona, ʻike ʻia hoʻi ʻo ke kila kalapona, he mea hao-kāpona hao me kahi kalapona maʻiʻo (wc) ʻoi aku ma lalo o 2%.Ma waho aʻe o ke kalapona, loaʻa i ke kila kalapona ka liʻiliʻi o ke silika, manganese, sulfur a me ka phosphorus.
Hiki ke hoʻokaʻawale ʻia ke kila kalapona i ʻekolu mau ʻāpana: ke kila kila kalapona, ke kila kila kila a me ke kila kila ʻoki manuahi.Hiki ke hoʻokaʻawale ʻia ke kila kila kila i ʻelua ʻano o ke kila kila no ke kūkulu ʻana a me ka hana mīkini.
E like me ke kalapona maʻiʻo hiki ke maheleia i haʻahaʻa kalapona kila (wc ≤ 0.25%), kalapona kila (wc 0.25% ~ 0.6%) a me kiʻekiʻe kalapona kila (wc> 0.6%).Wahi a ka phosphorus, hiki ke hoʻokaʻawale ʻia ka ʻike sulfur i ke kila kalapona maʻamau (loaʻa ka phosphorus, sulfur kiʻekiʻe), ke kila kalapona kiʻekiʻe (ʻo ka phosphorus, sulfur haʻahaʻa) a me ke kila kila kiʻekiʻe (loaʻa ka phosphorus, sulfur haʻahaʻa).
ʻOi aku ka kiʻekiʻe o ka ʻike kalapona i ke kila kalapona maʻamau, ʻoi aku ka kiʻekiʻe o ka paʻakikī a me ka ikaika, akā ua hoʻemi ʻia ka plasticity.
Nā kila hoʻolālā kalapona
ʻO kēia ʻano kila ka mea nui e hōʻoia i nā waiwai mechanical, no laila e hōʻike ana kāna papa i kona mau ʻano mechanical, me nā helu Q +, kahi o "Q" no ke kiko hua "Qu" ʻano o ka Hanyu Pinyin mua, ʻo ka helu e hōʻike i ka waiwai o ka hua. no ka laʻana, ua ʻōlelo ʻo Q275 i kahi kiko o 275MPa.Inā hōʻailonaʻia ka papa me nā leka A, B, C, D,ʻo ia hoʻi, heʻokoʻa ka maikaʻi o ka pae kila, aia ka nui o S, P i mea e hoʻemi ai i ka nui o ka maikaʻi o ke kila i mea e hoʻomaikaʻi ai.Inā kaha ʻia ka huapalapala “F” ma hope o ka papa, he kila paila ia, ua kaha ʻia “b” no ke kila semi-sedentary, ʻaʻole i kaha ʻia “F” a i ʻole “b” no ke kila noho.No ka la'ana, Q235-AF 'o ia ho'i ke kila paila A-grade me kahi kiko hua o 235 MPa, a 'o Q235-c 'o ia ho'i ke kila quiescent c-grade me kahi kiko hua o 235 MPa.
Hoʻohana mau ʻia nā kila hana kalapona me ka ʻole o ka mālama ʻana i ka wela a ma ke kūlana i hoʻolako pololei ʻia.ʻO ka maʻamau, ʻo Q195, Q215 a me Q235 mau kila he haʻahaʻa haʻahaʻa haʻahaʻa o ke kalapona, nā waiwai kuʻi maikaʻi, ka plasticity maikaʻi a me ka paʻakikī, loaʻa kahi ikaika, a ua ʻōwili pinepine ʻia i loko o nā papa lahilahi, nā kaola, nā paipu kila welded, etc., i hoʻohana ʻia i nā alahaka. nā hale a me nā hale ʻē aʻe a i ka hana ʻana i nā rivets maʻamau, nā wili, nā nati a me nā ʻāpana ʻē aʻe.ʻO nā kila Q255 a me Q275 ka hapa nui o ke kalapona, ka ikaika kiʻekiʻe, ʻoi aku ka maikaʻi o ka plasticity a me ka paʻakikī, hiki ke welded, a ʻōwili pinepine ʻia. e like me nā koʻokoʻo hoʻohui, nā mīkini, nā huila a me nā pine.
