Dabeecadda makaanikada

1.4112 waa bir aan lahayn kaarboon martensitic sare. Qalabka farsamaysan ee uu leeyahay inta badan waxa ka mid ah xoog, qallafsanaan, adayg, iwm. Kaarboonka iyo chromium-ka ku jira oo sarreeya awgeed, birta noocaan ahi waxay leedahay xoog iyo adayg sare waxayna u adkeysan kartaa cadaadis weyn iyo xirashada. Isla mar ahaantaana, sababtoo ah adkeysigeeda wanaagsan, nooca birta ah ma fududa in la isku dhejiyo waxaana loo isticmaali karaa goobo aad u adag. U adkaysta daxalka ka imanaya jawiga khafiifka ah, uumiga biyaha cusub, ammonia, batrool badan iyo walxo dabiici ah, iyo noocyo kala duwan oo aysiidh liidato ah. Heerkulku aad buu u hooseeyaa, iyo adayga ka dib deminta waa sarreeyaa. Adaggu inta badan waxa uu gaaraa HRC56-58. Waxay leedahay iska caabin daxalka wanaagsan (magnetic) iyo adkaanta xooggan.

Goobaha codsiga

Sababtoo ah 1.4112 birta aan lahayn waxay leedahay iska caabin heer sare ah iyo sifooyin farsamo, waxaa si weyn loogu isticmaalaa shidaalka, warshadaha kiimikada, injineernimada badda, baabuurta, cuntada iyo beeraha kale. Warshadaha batroolka iyo kiimikooyinka, sababtoo ah caabbinta daxalka aadka u fiican, waxaa loo isticmaalaa in lagu soo saaro reactors, dhuumaha iyo qalabka kale. Dhinaca injineernimada badda, waxaa loo isticmaalaa in lagu soo saaro qaybaha muhiimka ah ee maraakiibta iyo goobaha badda. Goobta baabuurta, waxaa loo isticmaalaa in lagu soo saaro qaybo ay ka mid yihiin hababka qiiqa iyo xirmooyinka. Goobta cuntada, waxaa loo isticmaalaa in lagu soo saaro qalabka jikada iyo qalabka cuntada lagu hagaajiyo sababtoo ah sifooyinka nadaafadda ee wanaagsan.

Waxqabadka habka

Hababka hab-socodka ee 1.4112 birta aan daahin waxay inta badan ka mid yihiin alxanka, daawaynta kulaylka iyo guryaha farsamaynta. Noocaan birta ah ayaa leh waxqabad alxanka oo wanaagsan waxaana lagu alxan karaa iyadoo la adeegsanayo habab alxanka oo kala duwan. Daaweynta kulaylku waxay wanaajin kartaa sifooyinkeeda farsamada iyo iska caabbinta daxalka, laakiin taxadar ayaa loo baahan yahay in la qaado si looga hortago dildilaaca ama qallafsanaanta ay keento kulaylka ama qaboojinta xad dhaafka ah. Waxay leedahay habayn wanaagsan waxaana loo isticmaali karaa leexinta, shiididda, qodista, tuubada iyo hawlaha kale ee habaynta. Khasaaraha uu leeyahay ayaa ah in uu dhegdheg yahay oo uu si degdeg ah u kululaado, laakiin waxa ay ka sahlan tahay in la ciido marka loo eego birta kaarboonka oo ay aad ugu sahlan tahay in lagu gooyo miinshaarka gacanta.
