Daidaitaccen haske bututun ne wani high daidaitaccen karfe bututun kayan da aka yi ta hanyar picking ko sanyi madaidaiciya. Saboda daidaito haske bututu ciki da waje bango ba oxidation layer, jure high matsin lamba ba leakage, high daidaito, high tsabtace, sanyi bending ba deformation, fadada, flattening ba cracks da dai sauransu kadan, don haka yafi amfani da samar da kayayyakin pneumatic ko na'ura mai amfani da ruwa abubuwa kamar silinda ko silinda, zai iya zama seamless bututu, kuma akwai walda bututu. Daidaitaccen haske bututun sunadarai ne carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. Ingancin carbon karfe, madaidaiciya madaidaiciya, oxide-free haske zafi magani (NBK jihar), ba lalacewa ganowa, karfe bututun ciki bango da musamman kayan aiki goge da kuma bayan high matsin lamba wanke, karfe bututun da tsalle-tsalle mai don tsalle-tsalle magani, biyu ƙarshen rufe don ƙura-tsalle magani.
Karfe bututu ciki da waje bangon high daidaito, high tsabtace, karfe bututu ba oxidation layer bayan zafi magani, ciki bangon tsabtace high, karfe bututu jure high matsin lamba, sanyi bending ba deformation, fadada, flattening ba cracks, da daidaito karfe bututu da Tianjin karni Midunion samar iya yin daban-daban rikitarwa deformation da kuma inji aiki magani. Karfe bututun launi: White da haske, tare da high karfe haske.
Babban amfani:
Mota, inji kayan haɗi da sauransu na ƙarfe bututun daidaito, tsabtace suna da babban bukatun inji. Daidaitaccen karfe bututun masu amfani ne ba kawai ga daidaito, tsabtace bukatun mafi girma masu amfani, saboda daidaitaccen haske bututun daidaito ne mai girma, haƙuri zai iya kiyaye a 2-8 waya, don haka yawancin inji sarrafawa masu amfani don ceton ma'aikata, kayan aiki, lokacin asarar, da seamless karfe bututun ko zagaye karfe ne a hankali canza zuwa daidaitaccen haske bututun.
