Bakin karfe na ƙarfe a halin yanzu shine mafi yawanci, ana amfani dashi, kuma mafi girman ƙarfe na ƙarfe akan kasuwa. The fiye gaba ka koma ga bakin karfe raga yafi nufin bakin karfe saka raga.
Da farko, bari mu fahimci tasirin abubuwa da yawa a cikin bakin karfe akan aikin bakin karfe:
1. Chromium (Cr) shine babban abin da ke tantance juriya na lalata bakin karfe. Karɓawar ƙarfe ta kasu kashi-kashi a cikin lalata da ɓarna da ba ta sinadarai ba. A yanayin zafi mai zafi, ƙarfe kai tsaye yana amsawa tare da iskar oxygen a cikin iska don samar da oxides (tsatsa), wanda shine lalatawar sunadarai; a zafin jiki na ɗaki, wannan ɓarna ba ta lalata sunadarai ba. Chromium yana da sauƙi don ƙirƙirar fim mai wucewa mai ƙarfi a cikin matsakaici mai ƙonawa. Wannan fim ɗin wucewa yana da tsayayye kuma cikakke, kuma yana da alaƙa da ƙarfe na tushe, gaba ɗaya yana raba tushe da matsakaici, ta haka yana inganta juriya na lalata allo. 11% shine mafi ƙarancin iyakar chromium a cikin bakin karfe. Karfe tare da chromium kasa da 11% galibi ba a kiran su bakin karfe.
2. Nickel (Ni) kyakkyawa ce mai tsayayya da lalata kuma babban abin da ke haifar da austenite a ƙarfe. Bayan an ƙara nickel zuwa bakin karfe, tsarin yana canzawa sosai. Yayin da abun ciki na nickel a cikin bakin ƙarfe ke ƙaruwa, austenite zai ƙaru, kuma juriya ta lalata, babban zafin juriya, da aiki na bakin karfe zai ƙaru, ta hakan yana inganta aikin aikin sanyi na ƙarfe. Sabili da haka, bakin karfe tare da abun ciki na nickel mafi girma ya fi dacewa don zana waya mai kyau da ƙananan waya.
3. Molybdenum (Mo) na iya inganta juriya na lalata bakin karfe. Ƙarin molybdenum zuwa bakin ƙarfe na iya ƙara ƙetare farfajiyar bakin ƙarfe, ta haka yana ƙara inganta juriya na baƙin ƙarfe. Molybdenum ba zai iya samar da hazo a cikin bakin karfe don haɓakar molybdenum ba, ta hakan yana haɓaka ƙarfin ƙarfin baƙin ƙarfe.
4. Carbon (C) yana wakiltar "0" a cikin kayan bakin karfe. A "0" yana nufin cewa abun cikin carbon bai kai ko daidai da 0.09%ba; "00" yana nufin cewa abun cikin carbon bai kai ƙasa ko daidai da 0.03%ba. Ƙara abun ciki na carbon zai rage juriya na lalata bakin karfe, amma zai iya ƙara ƙarfin baƙin ƙarfe.
Akwai nau'ikan nau'ikan bakin karfe da yawa, gami da austenite, ferrite, martensite da duplex bakin karfe. Saboda austenite yana da mafi kyawun ingantaccen aiki, ba magnetic bane kuma yana da babban tauri da filastik, ana amfani dashi don sarrafa raga na waya. Austenitic bakin karfe shine mafi kyawun bakin karfe. Austenitic bakin karfe yana da 302 (1Cr8Ni9), 304 (0Cr18Ni9), 304L (00Cr19Ni10), 316 (0Cr17Ni12Mo2), 316L (00Cr17Ni14Mo2), 321 (0Cr18Ni9Ti) da sauran samfura. Yin hukunci daga abun ciki na chromium (Cr), nickel (Ni), da molybdenum (Mo), 304 da 304L waya suna da kyakkyawan aiki gabaɗaya da juriya na lalata, kuma a halin yanzu sune waya tare da mafi girman adadin bakin karfe; 316 da 316L sun ƙunshi babban nickel, kuma yana ɗauke da molybdenum, ya fi dacewa da zane na wayoyi masu kyau, kuma yana da tsayayyar lalata da zafin zafin zafin. Rigon m-m-grained mesh ba wani bane face shi.
Bugu da kari, muna buƙatar tunatar da abokai na masana'antar ƙera waya cewa bakin karfe yana da tasirin lokaci. Bayan an sanya shi a cikin zafin jiki na ɗaki na ɗan lokaci, an rage ƙarfin jujjuyawar aiki, don haka ƙirar bakin ƙarfe bayan wani lokaci ya fi dacewa a yi amfani da shi azaman raga.
Saboda raga bakin karfe yana da halayen juriya na acid, juriya na alkali, juriya mai zafi mai ƙarfi, ƙarfin ƙarfi da juriya na abrasion, ya dace musamman don gwajin kwari da tace raga a ƙarƙashin yanayin muhalli na acid da alkali. Misali, ana amfani da masana'antar mai azaman allon laka, ana amfani da masana'antar fiber na sinadarai azaman matatar allo, ana amfani da masana'antar zaɓin lantarki azaman abin ɗorawa, da ƙarfe, roba, sararin sama, soja, magani, abinci, da sauran masana'antu. Ana amfani da iskar gas da tace ruwa da sauran rabuwa da kafofin watsa labarai.
