2. Bakin Karfe:
Bakin ƙarfe ƙarfe ne mai ƙarfe wanda ke ɗauke da kashi 10.5% na Chromium (Mafi ƙarancin ƙarfe). Bakin ƙarfe yana nuna halayen juriya ga tsatsa, saboda samuwar wani siririn Layer na Cr2O3 a saman sa. Wannan Layer kuma ana kiransa da Layer mai wucewa. Ƙara yawan Chromium zai ƙara juriya ga tsatsa na kayan. Baya ga Chromium, ana ƙara Nickel da Molybdenum don samar da kaddarorin da ake so (ko ingantattu). Bakin ƙarfe kuma yana ɗauke da adadi daban-daban na Carbon, Silicon, da Manganese.
An ƙara rarraba ƙarfe marasa ƙarfe zuwa kamar haka;
1. Bakin Karfe na Ferritic
2. Karfe Mai Kauri
3. Bakin Karfe na Austenitic
4. Bakin Karfe Duplex
5. Karfe Mai Tauri (PH) Mai Tsaftacewa
● Karfe Mai Bakin Karfe: Karfe Mai Bakin Karfe ya ƙunshi ƙarfe mai ƙarfe-Chromium tare da tsarin lu'ulu'u mai siffar cubic (BCC). Waɗannan gabaɗaya suna da maganadisu kuma ba za a iya taurare su ta hanyar maganin zafi ba amma ana iya ƙarfafa su ta hanyar yin aiki a sanyi.
● Bakin Karfe na Austenitic: Karfe na Austenitic suna da juriya ga tsatsa. Ba ya da maganadisu kuma ba ya da magani ga zafi. Gabaɗaya, ƙarfe na Austenitic suna da matuƙar sauƙin haɗawa.
● Karfe Mai Bakin Martensitic: Karfe Mai Bakin Martensitic suna da ƙarfi sosai kuma suna da tauri amma ba su da juriya ga tsatsa kamar sauran nau'ikan guda biyu. Waɗannan ƙarfe suna da matuƙar juriya ga injina, suna da ƙarfin maganadisu, kuma ana iya magance su da zafi.
● Bakin Karfe Duplex: Bakin Karfe Duplex ya ƙunshi wani tsari mai matakai biyu wanda ya ƙunshi hatsin ƙarfe ferritic da austenitic (watau Ferrite + Austenite). Bakin Karfe Duplex sun ninka ƙarfi kamar na bakin karfe austenitic ko ferritic.
● Karfe Mai Taurarewa (PH) Bakin Karfe: Ruwa Mai Taurarewa (PH) Bakin Karfe yana da ƙarfi sosai saboda ruwan sama mai taurarewa.
3. Karfe Mai Alloy
A cikin ƙarfe mai ƙarfe, ana amfani da nau'ikan abubuwan haɗin gwiwa daban-daban, don cimma kyawawan halaye da ake so (wanda aka inganta) kamar su iya aiki da walda, danshi, danshi, ƙarfi, tauri da juriya ga tsatsa, da sauransu. Wasu daga cikin abubuwan haɗin gwiwa da aka fi amfani da su da tasirinsu sune kamar haka;
● Manganese - Yana ƙara ƙarfi da tauri, yana rage juriya da sauƙin walda.
● Silicon – Ana amfani da shi azaman abubuwan cire sinadarai masu guba da ake amfani da su wajen yin ƙarfe.
● Phosphorus - Yana ƙara ƙarfi da tauri kuma yana rage juriya da tasirin tauri na ƙarfe.
● Sulfur – Yana rage juriya, taurin tasirin da ke kan ƙusa, da kuma sauƙin walda. Ana samunsa a cikin nau'in sinadarin sulfide.
● Tagulla – ingantaccen juriya ga tsatsa.
● Nickel - Yana ƙara taurarewa kuma yana tasiri ga ƙarfin ƙarfe.
● Molybdenum - Yana ƙara taurarewa kuma yana ƙara juriyar rarrafe na ƙananan ƙarfe.
4. Kayan aiki Karfe
Karfe masu kayan aiki suna da yawan sinadarin carbon (0.5% zuwa 1.5%). Yawan sinadarin carbon yana samar da tauri da ƙarfi. Ana amfani da waɗannan karafa galibi don yin kayan aiki da mayuka. Karfe masu kayan aiki suna ɗauke da adadi daban-daban na tungsten, cobalt, molybdenum, da vanadium don ƙara juriyar zafi da lalacewa, da kuma juriyar ƙarfe. Wannan ya sa ƙarfe masu kayan aiki suka dace sosai don amfani da su azaman kayan aikin yankewa da haƙa.
Kamfanin Jindalai Steel Group yana cike da mafi kyawun kayan ƙarfe a masana'antar. Jindalai zai iya taimaka muku zaɓar kayan ƙarfe masu dacewa don tabbatar da cewa kun sami abin da kuke buƙata da sauri lokacin da lokacin siye ya yi. Idan siyan kayan ƙarfe yana nan kusa, nemi farashi. Za mu samar muku da wanda zai ba ku ainihin samfuran da kuke buƙata da sauri.
