Kusiyana pakati pa giredi 8.8 ndi 12.9 mabawuti

fakitale yathu makamaka umabala mabawuti amphamvu kwambiria giredi 8.8 ndi 12.9, omwe muyezo wake ndi DIN933, DIN931, ndi DIN912, wokhala ndi mawonekedwe kuyambira M10 mpaka M48

Ndiye pali kusiyana kotanikalasi 8.8 carbon zitsulo mabawuti ndi giredi 12.9 mabawuti? Chonde onani kusanthula pansipa

1. Mphamvu kalasi ndi kuuma. Ma bawuti onse a giredi 8.8 ndi 12.9 ndi a mabawuti olimba kwambiri, koma kulimba kwa mabawuti a giredi 12.9 kumatha kufika 39 mpaka 44HRC, pomwe kulimba kwa ma bawuti a giredi 8.8 nthawi zambiri kumakhala pakati pa 22 ndi 33HRC. Kusiyana kwa kuuma kumeneku kumachitika makamaka chifukwa cha zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito. Maboti a Grade 12.9 nthawi zambiri amapangidwa ndi zitsulo za alloy (monga SCM435), pomwe ma bawuti a giredi 8.8 nthawi zambiri amapangidwa ndi zitsulo zapakatikati za kaboni.

2. Zochitika zogwiritsira ntchito. Maboti a Grade 12.9, chifukwa cha kuuma kwawo komanso mphamvu zawo, amagwiritsidwa ntchito kwambiri pazida zazikulu zamakina zomwe zimafunika kupirira katundu wamkulu, monga m'mafakitale a nsalu, jekeseni, ma hydraulic, ndi makina amakina. Grade 8.8 socket screws, chifukwa cha kuuma kwawo kochepa ndi mphamvu zawo, amagwiritsidwa ntchito kawirikawiri muzitsulo zazing'ono zamakina monga zinthu zamagetsi, zamagetsi, ndi zipangizo zamagetsi.

3. Mtengo. Mtengo wa ma bawuti a giredi 12.9 nthawi zambiri umakhala wapamwamba kuposa ma bawuti a giredi 8.8 chifukwa ali ndi mphamvu zochulukirapo komanso mphamvu zonyamula katundu. Mitengo ya fakitale yathu yonse ndi mitengo yamtengo wapatali, yomwe ndi yopindulitsa kwambiri. Ndikuyembekeza kulandira chithandizo chochulukirapo chamakasitomala, chonde onaninso tsamba lathuwww.cnzyl.comkudziwa zambiri za malonda athu ndi kampani yathu.
