Bakin ƙarfe
Babu wani ƙarfe wanda kayan aikinsu ya dogara da farko a kan abun ciki na ƙarfe da kuma wanda babu wasu abubuwa masu amfani da abubuwa waɗanda ake kira carbon waɗanda ake kira carbon ko carbon.
Carbon Karfe, wanda kuma ya kira carbon mara ƙarfe, yana nufin ƙarfe-carbon alloys da ke ɗauke da ƙasa da 2% carbon wc.
Karfe Carbon gabaɗaya yana ƙunshe da ƙananan silicon, manganese, sulfur da phosphorus ban da carbon.
Dangane da amfani da amfani da carbon karfe zuwa rukuni uku na carbon tsarin ƙarfe, carbon dabara tsarin karfe biyu na gina jiki don gini mai gina jiki;
Dangane da hanyar smelting za'a iya raba shi zuwa wutar gidan wuta mai fure, mai kazarta karfe da wutar ƙarfe mai lantarki;
Dangane da hanyar deoxidation za'a iya raba shi cikin tafasasshen ƙarfe (f), seedentary karfe (z), semi-sedanyy karfe (b) da seendenary karfe (tz) na musamman.
Dangane da abubuwan carbon na carbon na carbon (wc ≤ 0.25%), matsakaici carbon karfe (wc0.25%), carbon carbon karfe (wc> 0.6%);

A mafi girman abun ciki na carbon a janar carbon karfe, mafi girman ƙarfi, mafi girma ƙarfi, amma ƙananan filayen filastik.
Bakin karfe
Biki acid-mai tsayayya da karfe ana kiransa bakin karfe, wanda ya ƙunshi manyan ɓangarorin biyu: bakin karfe da acid na acid. A takaice, karfe wanda zai iya yin tsayayya da matsakaiciyar atmospherionic lalata ƙarfe, yayin da ƙarfe wanda zai iya yin tsayayya da lalata launin shayar da acid. Bakin karfe mai ƙarfi ne da ƙarfe 60% na baƙin ƙarfe kamar yadda matrix, nickel, molybdenum da sauran abubuwan abubuwan da suka kamata.
Lokacin da ƙarfe ya ƙunshi fiye da 12% chromium, karfe a cikin iska da tsarma nitric acid ba shi da sauƙi ga cortode da tsatsa. Dalilin shi ne comomium zai iya samar da ingantaccen Layer na fim ɗin Chromium On Ma'ana na Chromium On saman ƙarfe, yana kan kare ƙarfe daga lalata. Bakin karfe a cikin abun ciki na chromium gaba daya fiye da 14%, amma bakin karfe ba shi da cikakken-free. A bangarorin bakin teku ko wasu munanan iska, lokacin da iska chloride ya fice, amma waɗannan wuraren bakin karfe sun lalace ne kawai a cikin matrix na ciki.
Gabaɗaya magana, adadin Chrome Wcr mafi girma fiye da 12% na karfe yana da halaye na bakin karfe, ferentitic bakin karfe, ferentitic bakin karfe.
Bakin karfe yawanci ana rarraba shi ta hanyar kungiyar matrix:
1, ferritic bakin karfe. Dauke da 12% zuwa 30% chromium. Rashin juriya, mai ɗaukar nauyi da walwala tare da karuwa a cikin abin da juriya na Chromium da haɓaka ƙarfin cutar chlorium juriya sun fi sauran nau'ikan ƙarfe.
2, bakin karfe bakin karfe. Mai ɗauke da fiye da 18% chromium, ya ƙunshi kusan 8% Nickel da ƙananan adadin Molybdenum, titanium, nitrogen da sauran abubuwan. Cikakken aiki yana da kyau, na iya jure wa ɗakunan kafofin watsa labarai iri-iri.
3, Austenitic - ferritic Duplex bakin karfe. Dukkan ƙarfe na Austrenitic da ferritic bakin karfe, kuma yana da fa'idodin Superplasgplitplitplitplitplitplitplitplitplitplast.
4, Martensitic bakin karfe. Babban ƙarfi, amma matalauta filastik da wsibiri.
