Hōʻuluʻulu ʻike ʻike Alloy Steel

Hoʻokaʻawale kila kila

ʻO ka mea i kapa ʻiapaipu kila kilaʻo ia ka hoʻohui ʻana i kekahi mau mea hao ma ke kumu o ke kila kalapona, e like me Si, Mn, W, V, Ti, Cr, Ni, Mo, etc., hiki ke hoʻomaikaʻi i ka ikaika, paʻakikī, hardenability, weldability, etc. kila.hoʻokō.Hiki ke hoʻokaʻawale ʻia ke kila kila e like me ka ʻike o nā mea hao, a ma ka hana ʻoihana a me ke ola, e hoʻohana ʻia ke kila kila i nā ʻoihana kikoʻī, a he mea maʻamau nō hoʻi e hoʻokaʻawale e like me ke kumu.

Hoʻokaʻawale e like me ka ʻike o nā mea hoʻohui

ʻO ke kila kila haʻahaʻa:ʻo ka nui o nā mea hao ma lalo o 5%;

ʻO ke kila kila kila:ʻo ka nui o ka huila he 5 ~ 10%;

Ke kila kila kiʻekiʻe: ʻoi aku ka kiʻekiʻe o ka nui o ka alloy ma mua o 10%.

Hoʻokaʻawale ma ke kumu

Alloy structural steel: haʻahaʻa haʻahaʻa structural steel (ʻike ʻia ʻo ia ka mea maʻamau haʻahaʻa kila kila);ke kila carburizing, ke kila kinai a me ke kila, ke kila puna kila;kila hili kinipopo

Ke kila kila kila: ke kila ʻokiʻoki huila (me ke kila ʻoki haʻahaʻa haʻahaʻa, ke kila kiʻekiʻe);kila make kila (me ke kila make anu, kila make wela);kila no ke ana ana

Ke kila hana kūikawā: ke kila kila, ke kila wela, ke kila pale lole, etc.

Helu kila kila

Haʻahaʻa haʻahaʻa ikaika ikaika kūkulu kila

Hoʻonohonoho ʻia kona inoa inoa ma ka ʻāpana ʻekolu: ʻo ka huapalapala pinyin Kina (Q) e hōʻike ana i ka helu hua, ka waiwai palena o ka hua, a me ka hōʻailona papa maikaʻi (A, B, C, D, E).No ka laʻana, Q390A 'o ia hoʻi, haʻahaʻa-alloy kiʻekiʻe-ikaika structural kila me ka hua ikaika σs=390N/mm2 a me ka maikai pae A.

Ke kila kila kila

ʻEkolu mau ʻāpana kona inoa inoa: "ʻelua huahelu, ʻumi hōʻailona element + helu".ʻO nā huahelu mua ʻelua e hōʻike ana i 10,000 mau manawa o ka hapa nui kalapona ma ke kila, ʻo ka hōʻailona element e hōʻike ana i nā mea hoʻohui i loko o ke kila, a ʻo nā helu ma hope o ka hōʻailona element e hōʻike i 100 mau manawa o ka hapa nui o ka mea.Ke emi iho ka hapa nuipaa o na mea hoohuihui ma lalo o 1.5%, ma ke ano he mau mea wale no ka mea i hoikeia, aole nae ka helu helu;ke kaha like ka hakina nuipa awelika ≥1.5%, ≥2.5%, ≥3.5%, ..., 2 a me 3 mahope o na mea hoohuihui , 4, ...No ka laʻana, loaʻa iā 40Cr ka hakina kalapona awelika Wc=0.4%, a me ka hakina chromium awelika WCr<1.5%.Inā he kila kila kiʻekiʻe, e hoʻohui i ka "A" ma ka hope o ka papa.No ka laʻana, ʻo 38CrMoAlA ke kila no ke kila kila kila kila kiʻekiʻe.

Ke kila hili ʻana

E hoʻohui i ka "G" (ka hua mua o ka Chinese pinyin o ka huaʻōlelo "roll") i mua o ka inoa inoa, a ʻo ka helu ma hope e hōʻike ana i hoʻokahi kaukani ka hapa nui o ka chromium, a ʻaʻole i kaha ʻia ka hapa nui o ke kalapona. .No ka laʻana, ʻo ke kila GCr15 he kila wili me ka hapa nui o ka chromium WCr=1.5%.Inā loaʻa i ke kila chromium nā mea hoʻohuihui ʻē aʻe ma mua o ka chromium, ua like ke ʻano o ka hōʻike ʻana o kēia mau mea me ke kila kila maʻamau.ʻO nā kila wili liʻiliʻi he mau kila kiʻekiʻe kiʻekiʻe, akā ʻaʻole i hoʻohui ʻia ka "A" ma hope o ka papa.

Ke kila kila

ʻO ka ʻokoʻa ma waena o ke ʻano helu helu o kēia ʻano kila a me ke kila hoʻoheheʻe ʻia ʻo ia ka wā Wc<1%, hoʻohana ʻia hoʻokahi huahelu e hōʻike i ke kaukani manawa o ka hapa nui o ke kalapona;ke ≥1% ka hapa nui o ke kalapona, ʻaʻole i kaha ʻia.No ka laʻana, Cr12MoV kila he awelika ka hakina kalapona o Wc=1.45% ~ 1.70%, no laila, ʻaʻole i kaha ʻia; ʻo ka hapa nui nui o Cr he 12%, a ʻo nā hakina nuipaʻa o Mo a me V ua emi iho ma mua o 1.5%. .ʻO kekahi laʻana ʻo 9SiCr kila, kona awelika Wc = 0.9%, a ʻo ka awelika WCr he <1.5%. Akā naʻe, ʻokoʻa ke kila mea hana kiʻekiʻe, a ʻaʻole hōʻailona ʻia kona ʻāpana kalapona awelika no ka nui o ia. ʻO ke kila kila kila a me ke kila kiʻekiʻe kiʻekiʻe he kila kiʻekiʻe kiʻekiʻe, ʻaʻohe pono e kaha i ka "A" ma hope o kāna papa.

Ke kila kila a me ke kila wela

ʻO ka helu ma mua o kēia ʻano papa kila e hōʻike ana i hoʻokahi kaukani ka nui o ka hakina kalapona.No ka laʻana, 3Crl3 kila 'o ia hoʻi ka awelika hakina nui Wc = 0.3%, a me ka awelika hakina lehulehu WCr = 13%. I ka manawa o ka hakina nuipa o kalapona Wc ≤ 0.03% a me Wc ≤ 0.08%, ua hoikeia e "00" a "0" i mua o ka brand, e like me 00Cr17Ni14Mo2, 0Cr19Ni9 kila, etc.
