Qalabka farsamada ee boolalku waxay saameeyaan alaabta ceeriin iyo daaweynta kulaylka. Guud ahaan, alaabta ceeriin ayaa saameyn weyn ku leh sifooyinka boolal sababtoo ah sifooyinka alaabta ceeriin ayaa go'aamiya xadka sare ee daaweynta kulaylka.. Tusaale ahaan, alaabta ceeriin ah oo aan lahayn Cr weligood ma gaari karaan xoogga xajinta ee a 10.9 bool darajada.

Guud ahaan, marka macaamiishu aysan haysan shuruudo gaar ah, waxaan kugula talineynaa in la go'aamiyo alaabta ceeriin ee wax soo saarka bolt iyadoo lagu saleynayo isticmaalka macaamilka. Tusaale ahaan, warshadaha dhismaha, waxaa lagu talinayaa in la isticmaalo boolal darajada 8.8 ama ka sareeya dhismayaasha birta, iyo warshadaha baabuurta, boolal darajo 10.9 ama ka sareeya ayaa lagula talinayaa isku xirka.

Marka macaamiishu ay leeyihiin shuruudo gaar ah oo loogu talagalay darajada boodhka, Waxaan sida caadiga ah u dooranaa boolal si waafaqsan heerka ISO898 ee boolal mitirka ah.

Kuwa soo socda ayaa ah shuruudaha loogu talagalay alaabta ceeriin ee bolt ee ISO898:

a Haddi khilaaf dhaco, Falanqaynta alaabta ayaa khuseysa.
b Waxa ku jira boron ayaa gaadhi kara 0,005 %, Haddii boron aan waxtar lahayn lagu xakameeyo ku darida titanium iyo/ama aluminium.
c Ku xirayaasha qaboojiyaha been abuurka ah ee fasalada hantida 4.6 iyo 5.6, daaweynta kulaylka ee siligga loo isticmaalo foornada qabowga ama qabowga la been abuurtay
xiraha laftiisa ayaa laga yaabaa inay lagama maarmaan noqoto si loo gaaro ductility loo baahan yahay.
d birta goynta bilaashka ah ayaa loo ogol yahay fasalada hantida leh baaruudda ugu badan ee soo socota,  fosfooraska iyo macdanta rasaasta:S: 0,34 %; P: 0,11 %; Pb: 0,35 %.
e Haddii ay dhacdo birta boron kaarboon ee cad oo leh kaarboonka hoose 0,25 % (falanqaynta kabka), maadada manganese ugu yar waa inay ahaataa 0,6 % fasalka hantida 8.8 iyo 0,7 % fasalada hantida 9.8 iyo 10.9.
f Qalabka fasalada hantida,  waa inay jirtaa awood adag oo ku filan oo lagu hubinayo qaabdhismeed ka kooban
qiyaastii 90 % martensite ee xudunta u ah qaybaha dunta ee xirmooyinka ku jira xaalad "sida-adag" ka hor inta aan la kicin. g Birtan daawaha ah waa inay ka koobnaataa ugu yaraan mid ka mid ah walxahan soo socda inta ugu yar ee la bixiyay: chromium 0,30 %,  nikkel 0,30 %, molybdenum 0,20 %, vanadium 0,10 %. Halka canaasirta lagu caddeeyey isku darka laba, saddex ama afar waxayna leeyihiin waxyaabo alloy ah oo ka yar kuwa kor lagu sheegay, qiimaha xaddidan ee lagu dabaqi karo go'aaminta fasalka birta waa 70 % wadarta qiimaha xadka shakhsiyeed ee kor lagu sheegay labada, saddex ama afar walxood oo khuseeya.
h Xirnayaasha laga soo saaray walxo fosfat ah waa in laga gooyaa ka hor daaweynta kulaylka; Maqnaanshaha lakabka fosfooraska cad ee hodanka ku ah waa in lagu ogaadaa hab tijaabo ah oo ku habboon.
Waxaa lagu talinayaa in taxaddar la sameeyo marka la isticmaalayo fasalka hantida 12.9/12.9 waa la tixgeliyaa. Awoodda ee xidheha soo saaraha, waa in la tixgeliyo shuruudaha adeegga iyo hababka wax lagu maqlo. Deegaanku waxay sababi karaan dildilaaca daxalka ee xirayaasha sida la warshadeeyay iyo sidoo kale kuwa dahaarka leh.

Haddii aad qabtid su'aal kale oo ku saabsan wax soo saarka boolalka, pls dareento inaad nala soo xidhiidho.
