(2) birta daawaha ah: a. birta daawaha hoose (content element Alloy wadarta guud 5% ama ka yar); B. ee birta daawaha ah (wadarta guud ee walxaha alloy> 5 ~ 10%); C. bir daawaha sare leh (wadarta guud ee walxaha alloy> 10%).
3, iyadoo loo eegayo habka samaynta ee kala-soocidda
(1) bir been abuur ah; (2) birta la shubo; (3) bir duuban oo kulul, (4) bir qaboojin leh.
4, sida ku cad kala soocida qaab-dhismeedka yar yar

(2) waa xaaladda dabka: a. birta luul; B. birta bainite; C. birta martensitic; D. birta austenitic.
(3) iyada oo aan isbeddel weji lahayn ama qayb ka mid ah isbeddelka wejiga
5, iyadoo loo eegayo ujeeddada kala soocidda
(1) dhismaha iyo birta injineernimada: a. birta qaab dhismeedka kaarboon ee caadiga ah; B. birta qaab dhismeedka alloy hoose; C. birta la xoojiyay.
(2) Bir dhismeed: a. wax soo saarka mishiinada oo la demiyo iyo bir dabcay: (a) birta qaab dhismeedka; (b) birta adag ee dusha sare: oo ay ku jirto birta carburizing, permeability of ammonia steel, birta deminta dusha sare; (c) birta goynta bilaashka ah; (d) birta samaynaysa balaastiig qabow: oo ay ku jiraan birta qabow-samaysan, birta madaxa qabow.
B. birta guga
C. birta sidata
(3) Qalabka birta ah: a. qalabka kaarboon birta; B. birta aluminiumka ah; C. Biraha qalabka xawaaraha sare.
(4) waxqabadka gaarka ah ee birta: a. birta aan lahayn aashitada; B. birta u adkaysata kulaylka, oo ay ku jiraan xoojinta kulaylka oksaydhka, birta, valve birta; C. birta daawaha korantada; D. xidho birta u adkaysata; E. birta cryogenic; F. birta korantada.
(5) biraha xirfada leh, sida Buundooyinka birta leh, birta markabka, birta kuleyliyaha, birta weelka cadaadiska, mishiinada beeraha, birta, iwm.
6, kala saarid dhamaystiran
(1) birta caadiga ah
A. Q195 kaarboon qaabdhismeedka birta: (a); (b) Q215 (A, b); (c) Q235 (A, B, c); (d) Q255 (A, B); Q275 (e).
