Chiyambi cha zida zopangira mabawuti amphamvu kwambiri

Timasiyanitsa chitsulo chochepa cha carbon, sing'anga mpweya zitsulo, mkulu mpweya zitsulo ndi aloyi zitsulo monga zilili mpweya mu carbon zitsulo.

1 Chitsulo chochepa cha carbon C% ≤ 0.25% chimatchedwa A3 zitsulo ku China. Amatchedwa 10081015181022 kunja. Amagwiritsidwa ntchito kwambiri pama bawuti a Giredi 4.8,gr4 nthiti, zomangira zazing'ono ndi zinthu zina popanda kuuma zofunika. (Zindikirani: Zinthu 1022 zimagwiritsidwa ntchito kwambiri pobowola misomali.) Izi sizoyeneramabawuti amphamvu kwambiri.

2.Medium mpweya zitsulo> 0.25%, C1035 35 #, 35ACR, ndiGulu la 8.8 hex boltskukula kwake, koma kukula kwakukulu ndi makulidwe otentha, sikungagwiritsidwe ntchito.

3 High carbon zitsulo C%>0,45%. Kawirikawiri, chitsulo ichi ndi chagr8.8 mabawuti, zazikulu zonyezimira zotentha.

4 Aloyi Chitsulo: zinthu aloyi amawonjezedwa plain carbon zitsulo kuonjezera zina zapadera zitsulo, monga 40Cr, 35CrMo, 42CrMo., SCM435, 10B38. Zomangira za Fangsheng zimapangidwa makamaka ndi chitsulo cha SCM435 chrome molybdenum alloy, chomwe chimapangidwa makamaka ndi C, Si, Mn, P, S, Cr ndi Mo. Kampani yathu imagwiritsa ntchito 40Cr kapena 35CrMo kunyadira.10.9 mabawuti, 42CrMo, SCM435 kupangaGr12.9 mabawuti.

Ngati fakitale imagwiritsa ntchito zopangira zolakwika, iwo adzalephera kukwaniritsa kalasi yomwe akufuna panthawi yakutentha mankhwala, ndipo khalidweli lidzakhala losayenerera
Malingaliro a kampani Ningbo Zhongli Bolts Manufacturing Co.ltdidakhazikitsidwa mu 2003, ndiyeakatswiri mabawuti ogulitsa ku China. Ili ndi magulu amphamvu aukadaulo komanso opanga zaka zambiri zapitazi, Ubwino ndiwabwino kwambiri komanso wosasunthika, zogulitsa zake ndizolimba kwambiri za DIN ndi ma ANSI ma bolt apamwamba, mtedza wa Hex, ma washer osavuta.
