Fasali na Musamman Karfe:
Idan aka kwatanta datalakawa, karfe na musamman yana da sifofin tsarkakakkiyar tsarkakakkiyar, ingantaccen tsari da madaidaicin daidai:
(1) babban tsarkakakku.Abubuwan da ke ciki da inclusions (gami da ƙirar ƙarfe tare da melting maki) a cikin karfe za a iya rage. Lokacin da tsarkakakken karfe ya ƙaru zuwa wani iyaka, ba wai kawai asalin kaddarorin karfe za a iya inganta ba, har ma ana iya inganta kaddarorin karfe. Misali, abun ciki na oxygen a ciki yana raguwa daga 30 × 10-6 zuwa 5 × 10-6, kuma rayuwa tana ƙaruwa sau 30. Universal Austenitic bakin ciki ba su da kariya ga damuwa ga lalata a lokacin da abun ciki na phosphorus ya rage zuwa 3 × 10-6. A ƙarshen karni na 20, matakin tsarkakakkiyar (10) na ƙarfe wanda samarwa shine: carffen ≤1, oxygen ≤1, oxsphogen ≤25, phosphorus ≤25, phosphorus ≤25, phosphorus ≤25, phosphorus ≤25.

(2) babban daidaituwa.Rubuce-rubucen da ke haifar da tsari mara kyau da kayan ƙarfe, wanda yake ɗayan mahimman dalilai na farkon gazawar karfe da wahala a cikin amfani da kayan ƙarfe. Yakamata samar da zane na zamani ya zama daidaituwa na karfe: Mota Gearfen wahala bandation Band Sain shine ± 3hrc; Abubuwan da ke ciki na carbon, nickel, molybdenum ≤ ± 0.01%, da manganese da Chromium ≤ ± 0.02% aka sarrafa daidai. The grain size of bearing steel after quenching is spherical and the size fluctuation is 0.8± 0.2 μm. Abubuwan da ke cikin kayan aikin na hawaye na hawaye mai tsattsauran ido (Z-faifan Karfe) a cikin tsunduman ƙasa, musamman buƙatun filastik da ke da alaƙa iri ɗaya ne.
(3) Tsarin aiki mai kyau.Dogara mai ɗorewa mai ɗorewa shine kawai ƙarfafa kayan ƙarfe wanda zai iya ƙara ƙarfin ƙarfe ba tare da raguwa ko ƙara ƙaruwa ba. Misali, lokacin da hatsi mai ƙarfi ƙarfi bakin karfe af77 zuwa 2 60 μm, karfin hadic yana ƙaruwa daga 100 zuwa 220mpAls. Irin da yake da zafin jiki na zazzabi na farantin karfe na farantin karfe a cikin jirgin ruwa mai ƙarfi na nuclear shine 15 ~ 70 ℃. Lokacin da girman carbide a cikin bearind karfe yana da kyau a ≤0μm, rayuwa mai ɗaukar nauyi zai kasance sosai inganta.
(4) Babban daidaito.Steals na musamman yakamata ya sami ingantaccen ingancin haƙuri da haƙuri. Daidaitaccen hasken zafi birge karfe ya tashi zuwa ± 0.1mm, da haƙuri mai haƙuri na coil ya tashi zuwa ± 0.003mm.
