Hōʻuluʻulu Manaʻo ʻIke o ke Kila Alloy

Helu kila kila

Ke kila kūkulu ikaika kiʻekiʻe me ka metala haʻahaʻa

Ua hoʻonohonoho ʻia kona inoa hōʻailona ma ke ʻano he ʻekolu ʻāpana: ka leka pinyin Kina (Q) e hōʻike ana i ke kiko hua, ka waiwai palena hua, a me ka hōʻailona pae maikaʻi (A, B, C, D, E). No ka laʻana, ʻo Q390A ke ʻano o ke kila kūkulu haʻahaʻa-metala me ka ikaika hua σs=390N/mm2 a me ka pae maikaʻi A.

Ke kila kūkulu metala

ʻO kona inoa hōʻailona he ʻekolu ʻāpana: "ʻelua mau huahelu, ʻumi mau hōʻailona mea + nā helu". Hōʻike nā huahelu mua ʻelua i 10,000 manawa o ka hapa nui kalapona awelika i loko o ke kila, hōʻike ka hōʻailona mea i nā mea hoʻohuihui i loko o ke kila, a hōʻike nā helu ma hope o ka hōʻailona mea i 100 manawa o ka hapa nui awelika o ka mea. Ke emi ka hapa nui awelika o nā mea hoʻohuihui ma mua o 1.5%, ʻo ka mea maʻamau, ʻo nā mea wale nō i hōʻike ʻia akā ʻaʻole ka waiwai helu; i ka wā he ≥1.5% ka hapa nui awelika, ≥2.5%, ≥3.5%, ..., 2 a me 3 ua hōʻailona like ʻia ma hope o nā mea hoʻohuihui, 4, . . . No ka laʻana, he hapa nui kalapona awelika ko 40Cr Wc=0.4%, a he hapa nui chromium awelika WCr<1.5%. Inā he kila kiʻekiʻe kiʻekiʻe, e hoʻohui i ka "A" ma ka hopena o ka papa. No ka laʻana, ʻo ke kila 38CrMoAlA no ke kila kūkulu metala kiʻekiʻe.

Ke kila hali ʻōwili

E hoʻohui i ka "G" (ka leka mua o ka pinyin Kina o ka huaʻōlelo "roll") ma mua o ka inoa inoa, a ʻo ka helu ma hope ona e hōʻike ana i hoʻokahi tausani manawa o ka hapa nui o ka chromium, a ʻaʻole i hōʻailona ʻia ka hapa nui o ke kalapona. No ka laʻana, ʻo ke kila GCr15 he kila e hali ana i ka ʻōwili me ka hapa nui awelika o ka chromium WCr = 1.5%. Inā loaʻa i ke kila e hali ana i ka chromium nā mea hoʻohuihui ʻē aʻe ma mua o ka chromium, ʻo ke ʻano hōʻike o kēia mau mea ua like ia me ke kila hoʻonohonoho alloy maʻamau. ʻO nā kila e hali ana i ka ʻōwili he mau kila kiʻekiʻe kiʻekiʻe, akā ʻaʻole i hoʻohui ʻia ka "A" ma hope o ka papa.

Mea kila kila

ʻO ka ʻokoʻa ma waena o ke ʻano helu o kēia ʻano kila a me ke kila hoʻonohonoho hui ʻo ia ka wā ʻo Wc <1%, hoʻohana ʻia kekahi huahelu e hōʻike i nā tausani manawa o ka hapa nui o ke kalapona; i ka wā ʻo ka hapa nui o ke kalapona he ≥1%, ʻaʻole i hōʻailona ʻia. No ka laʻana, ʻo ke kila Cr12MoV he hapa nui kalapona awelika o Wc = 1.45% ~ 1.70%, no laila ʻaʻole i hōʻailona ʻia; ʻo ka hapa nui awelika o Cr he 12%, a ʻo nā hapa nui o Mo a me V ʻelua ma lalo o 1.5%. ʻO kekahi laʻana ʻo ke kila 9SiCr, ʻo kona awelika Wc = 0.9%, a ʻo ka awelika WCr he <1.5%. Eia nō naʻe, he ʻokoʻa ke kila mea hana wikiwiki, a ʻaʻole i hōʻailona ʻia kona hapa nui kalapona awelika ʻaʻohe mea nui. No ka mea, ʻo ke kila mea hana hui a me ke kila mea hana wikiwiki he kila kiʻekiʻe ke ʻano kiʻekiʻe, ʻaʻohe pono e hōʻailona "A" ma hope o kona ʻano.

Ke kila kila a me ke kila kūpaʻa wela

ʻO ka helu ma mua o kēia ʻano kila e hōʻike ana i hoʻokahi tausani manawa o ka hapa nui kalapona. No ka laʻana, ʻo ke kila 3Crl3 ʻo ia hoʻi ka hapa nui awelika ʻo Wc = 0.3%, a ʻo ka hapa nui awelika ʻo WCr = 13%. Ke ʻoi aku ka nui o ka hapa o ke kalapona Wc ≤ 0.03% a me Wc ≤ 0.08%, ua hōʻike ʻia e "00" a me "0" ma mua o ka lama, e like me 00Cr17Ni14Mo2, 0Cr19Ni9 kila, a pēlā aku.
