Rarraba na carbon karfe

Sama da ton biliyan 1.5 na karafa ne ake samar da su a duk shekara, wadanda ake amfani da su wajen kera kayayyaki iri-iri, kamar su dinkin allura da katako na gine-ginen gine-gine.Carbon karfe shine mafi yawan amfani da gami da ƙarfe, yana lissafin kusan kashi 85% na duk abubuwan da Amurka ke samarwa.Abubuwan da ke cikin carbon na samfurin yana cikin kewayon 0-2%.Wannan carbon yana rinjayar microstructure na karfe, yana ba shi ƙarfin almara da taurinsa.Wadannan gami kuma sun ƙunshi ƙananan adadin manganese, silicon da jan karfe.Karfe mai laushi shine kalmar kasuwanci don ƙarfe mai laushi tare da abun ciki na carbon a cikin kewayon 0.04-0.3%.

Carbon karfe za a iya rarraba bisa ga sinadaran abun da ke ciki da kuma kaddarorin samfurin.Ƙarfe mai laushi kuma yana shiga cikin nau'in ƙarfe mai laushi saboda yana da irin wannan abun ciki na carbon.Karfe na carbon na yau da kullun baya ƙunshe da gami kuma ana iya raba shi zuwa rukuni huɗu:

1. Low carbon karfe

Ƙarfe mai laushi yana da abun ciki na carbon na 0.04-0.3% kuma shine mafi yawan darajar carbon karfe.Ƙarfe mai laushi kuma ana ɗaukar ƙarfe mai laushi kamar yadda aka ayyana shi azaman yana da ƙarancin abun ciki na carbon na 0.05-0.25%.M karfe ne ductile, sosai malleable kuma za a iya amfani da a mota sassa jiki, sheet da waya kayayyakin.A babban ƙarshen ƙarancin abun ciki na carbon, da har zuwa 1.5% manganese, kayan aikin injiniya sun dace da tambari, ƙirƙira, bututu marasa ƙarfi da faranti na tukunyar jirgi.

2. Matsakaicin carbon karfe

Matsakaicin ƙarfe na carbon yana da abun ciki na carbon a cikin kewayon 0.31-0.6% da abun ciki na manganese a cikin kewayon 0.6-1.65%.Ana iya magance wannan ƙarfe da zafi kuma a kashe shi don ƙara daidaita ƙananan ƙwayoyin cuta da kaddarorin inji.Shahararrun aikace-aikacen sun haɗa da axles, axles, gears, dogo da ƙafafun jirgin ƙasa.

3. High carbon karfe

Babban karfen carbon yana da abun ciki na carbon na 0.6-1% da abun ciki na manganese na 0.3-0.9%.Abubuwan da ke da babban ƙarfe na carbon sun sa ya dace don amfani da maɓuɓɓugar ruwa da waya mai ƙarfi.Waɗannan samfuran ba za a iya walda su ba sai dai idan an haɗa dalla dalla dalla dalla dalla-dalla na maganin zafi a cikin hanyar walda.Ana amfani da ƙarfe mai ƙarfi don yankan kayan aiki, waya mai ƙarfi da maɓuɓɓugan ruwa.

4. Ultra-high carbon karfe

Ƙarfafan ƙarfe masu ƙarfi suna da abun ciki na carbon na 1.25-2% kuma an san su da gwanayen gwaji.Tempering yana samar da ƙarfe mai wuyar gaske, wanda ke da amfani ga aikace-aikace kamar wuƙaƙe, axles ko naushi.
