Hōʻuluʻulu ʻike ʻike Alloy Steel

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 huaʻōlelo mua o ka pinyin Kina 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, ʻo ke kila Cr12MoV ka hapa nui kalapona o Wc=1.45%~1.70%, no laila ʻaʻole i kaha ʻia; ʻo ka hapa nui o ka 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, he ʻokoʻa ke kila kila kiʻekiʻe, a ʻaʻole hōʻailona ʻia kona ʻāpana kalapona ma muli o ka nui o ia.

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, o ka awelika hakina nui Wc = 0.3%, a me ka awelika nuipa hapa hakina WCr = 13%. I ka nuipa o ka hakina o kalapona Wc ≤ 0.03% a me Wc ≤ 0.08%, ua hōʻike 'ia e "00" a me "0" i mua o ka momoku ahi, Nir1700, Nir1901. etc.
