A lokuta da yawa mutane sun fi zaɓin ƙarfe maimakon carbon karfe galibi suna da abubuwan da suka biyo baya.

(1) Rashin ƙarfin ƙarfi

Carbon karfe amfani da ruwa quenching, da m quenching diamita zuwa 15 ~ 20mm, 20mm diamita mafi girma ga sassa, ko da ruwa ba zai iya quench hardenability, ba zai iya tabbatar da cewa dukan sashe don samun guda inji Properties.Don haka, don buƙatar manyan sassa, ƙarfe na carbon ba lallai ba ne.Karfe yana da babban ƙarfin ƙarfi, ana iya amfani dashi a cikin kera babban nau'in giciye na sassa masu rikitarwa.

(2) High-zazzabi ƙarfi, low carbon karfe, ja taurin bambanci

Lokacin da carbon-carbon karafa a yanayin zafi sama da 200℃, Karfinsa da taurinsa za su ragu nan ba da jimawa ba.Kyakkyawan kwanciyar hankali bayan tempering karfe.Jan taurin, kuma yana iya aiki a yanayin zafi mafi girma.

(3) Ba tare da kyakkyawan aiki na gaba ɗaya ba

Misali, lokacin amfani da quenching don ƙoƙarin samun kyakkyawan aiki na gabaɗaya, don tabbatar da ƙarfin ƙarfi, ƙarfin ƙarfi yana da ƙasa, don tabbatar da ƙaƙƙarfan ƙarfi, ƙarfin ƙananan gefe.Wannan shi ne saboda rashin kwanciyar hankali na carbon karfe tempered dalili.Saboda haka, sakamakon carbon karfe gami matalauta overall yi fiye da cewa na gami karfe yana da kyau tauri.

(4) Ba tare da kaddarori na musamman ba

Alal misali, buƙatar ƙarfin zafin jiki ko tonicity, anti-oxidation, juriya na lalata, lantarki na musamman, Magnetic, da dai sauransu, ba za a iya samu tare da carbon karfe, gami karfe iya zabar saduwa da sama bukatun.

Karfe na carbon kuma yana da wasu fa'idodi, kamar ta hanyar canza abun ciki na carbon da isassun magani mai zafi, ana iya samun shi a cikin ayyukan samar da masana'antu da yawa da ake buƙata.Saboda ƙarancin samar da ƙarfe na carbon, farashi, sauƙi, kyakkyawan aiki mai kyau, masana'antar har yanzu ita ce mafi yawan kayan aikin ƙarfe da aka yi amfani da su, suna lissafin sama da 80% na jimlar adadin ƙarfe.

Don ramawa ga rashin amfani da carbon karfe, carbon karfe na USB bisa ga sane ƙara wasu alloying abubuwa, da ake bukata don samun dama gami Properties.Duk da yake karfe yana da kyau kwarai ko na musamman yanayi, yana da matukar muhimmanci karfe, za a iya daidaita da bukatun na yankin, amma akwai da yawa disadvantages na karfe, yafi cewa alloying abubuwa, da karfe smelting da sarrafa matalauta yi fiye da carbon karfe, da farashin ya fi tsada.Dangane da ka'idar zaɓi mai ma'ana, lokacin da ƙarfe na carbon ya cika buƙatun, yakamata kuyi ƙoƙarin amfani da ƙarfe na carbon.
