Hordhaca alaabta ceeriin ee soo saarida boolal-xoog-sare

Waxaan kala soocnaa birta kaarboonka hooseeya, birta kaarboonka dhexdhexaadka ah, birta kaarboonka sare iyo birta daawaha iyadoo loo eegayo kaarboonka birta kaarboonka.

1 Bir kaarboon hoose C% ≤ 0.25% waxaa guud ahaan loogu yeeraa birta A3 ee Shiinaha. Waxaa asal ahaan loogu yeeraa 10081015181022 dibadda. Waxaa inta badan loo isticmaalaa bolts Fasalka 4.8,Gr4 nuts, boolal yaryar iyo alaabooyin kale oo aan lahayn shuruudo adag. (Fiiro gaar ah: 1022 walxo ayaa inta badan loo isticmaalaa qodista cidiyaha.) Qalabkani kuma habboonaboolal xoog sare.

2. Dhexdhexaad kaarboon bir>0.25%, C1035 35#, 35ACR, waxaa loogu talagalayFasalka 8.8 hex boolalcabbirrada, laakiin cabbirrada waaweyn iyo cabbirrada foornada kulul, lama isticmaali karo.

3 Bir kaarboon sare C%>0.45%. Sida caadiga ah, birtan waxaa loogu talagalayGr8.8 boolal, cabbirro foorno kulul.

4 birta daawaha: canaasiirta daawaha waxaa lagu daraa birta kaarboonka cad si loo kordhiyo qaar ka mid ah sifooyinka gaarka ah ee birta, sida 40Cr, 35CrMo, 42CrMo., SCM435, 10B38. Fangsheng screws waxay inta badan ka samaysan yihiin SCM435 chrome molybdenum alloy steel, inta badan waxay ka kooban yihiin C, Si, Mn, P, S, Cr iyo Mo. Shirkadeena waxay isticmaashaa 40Cr ama 35CrMo si ay ugu faanto10.9 boolal, 42CrMo, SCM435 si loo soo saaroGr12.9 boolal.

Haddii warshadu isticmaasho alaabta ceeriin ee khaldan, waxay ku guuldareysan doontaa inay gaaraan darajada la rabo ee habkadaaweynta kulaylka, tayadana waxay noqon doontaa mid aan u qalmin
Hal qayb oo ka mid ah Ningbo Zhongli Bolts Production Co., Ltdwaxaa la aasaasay 2003, kaas oo ahalaab-qeybiyaha boolal xirfadeed ee Shiinaha. Waxay leedahay koox farsamo iyo kooxo wax soo saar leh sannado badan oo la soo dhaafay, Tayada ayaa ah mid aad u fiican oo xasilloon, inta badan alaabadu waa DIN iyo ANSI heer sare oo boolal sare leh, Hex nuts, dhaqdhaqaajiyaasha cad.
