Waqtigan xaadirka ah, xirayaasha suuqa inta badan waxaa ka mid ah birta aan la taaban karin, birta kaarboon, naxaas, aluminium aluminium afar nooc oo alaab ceeriin ah..
1. Birta Kaarboon. Si walxaha birta kaarboon ee ka kooban kaarboon si loo kala saaro inta u dhaxaysa birta kaarboon yar, birta kaarboon dhexdhexaad ah, birta kaarboonka sare iyo birta daawaha ay.
(1) birta kaarboon ee hooseeya C%≤ 0.25% Shiinaha guud ahaan waxaa loo yaqaannaa birta A3. Dalalka kale iyo gobollada asal ahaan loo yaqaan 1008, 1015, 1018, 1022, iwm (Fiiro gaar ah: Drill-tailboolalGuud ahaan waxaa loo isticmaalaa 1022 alaabta ceeriin ah.)
(2) Bir kaarboon dhexdhexaad ah 0.25% 0.60%. Waqtigan xaadirka ah suuqa asal ahaan wax codsi ah ma jiraan.
(3) birta daawaha: birta kaarboonka caadiga ah si loogu daro qaybaha daawaha, iyadoo lagu darayo qaar ka mid ah sifooyinka gaarka ah ee birta dhismaha: sida 35, 40 chromium-molybdenum, SCM435, 10B38. 12.9 boolal oo isticmaalaya SCM435 chromium-molybdenum alloy steel, qaybaha muhiimka ah waa C, Si, Mn, P, S, Cr, Mo.
2. Bir aan lahayn. Fasalka sifada: 45, 50, 60, 70, 80. inta badan waxay u qaybsantaa martensite (18% Cr, 8% Ni) caabbinta heerkulka wanaagsan, caabbinta daxalka wanaagsan. a1, a2, a4 martensite (13% Cr) caabbinta daxalka daciifka ah, xoog sare, caabbinta xirashada wanaagsan. c1, c2, c4430 ahama. 18% xanaaqa Cr ayaa ka fiican, iska caabinta daxalka ayaa ka xoog badan austenite. Alaabada ceyriinka ah ee suuqa hadda jira waxa inta badan loo qaybiyaa SUS302, SUS304, SUS316 darajo ahaan.
3. Copper. Qalabka caadiga ah ee naxaasta, daawaha naxaasta guduudan. Suuqa guud ahaan waxaa loo isticmaalaa H62, H65, H68 naxaasta alaabada caadiga ah.
4. Cufnaanta aluminiumka aluminiumku waa mid hooseeya, laakiin xoogga cadaadiska ayaa aad u sarreeya, u dhow ama xitaa ka badan birta kabka kulaylka u adkaysta, caag wanaagsan, waxaa lagu samayn karaa noocyo kala duwan oo aluminium ah, oo leh koronto wanaagsan, wareejin kulaylka iyo daxalka. iska caabin ah, isticmaalka warshadaha waa mid aad u ballaaran, qadarka birta labaad oo kaliya.
- Biraha daawaha waxa kale oo loola jeedaa birta chromium-molybdenum aluminium, sida SCM435, iwm.
