Nkhani

Pakali pano, fasteners pa msika makamaka monga zitsulo zosapanga dzimbiri, mpweya zitsulo, mkuwa, zotayidwa aloyi mitundu inayi ya zipangizo..

1. Chitsulo cha carbon. Kuti mpweya zitsulo zakuthupi zikuchokera mpweya kusiyanitsa otsika mpweya zitsulo, sing'anga mpweya zitsulo, mkulu mpweya zitsulo ndi aloyi zitsulo.

(1) chitsulo chochepa cha carbon C%≤ 0.25% China imatchedwa A3 chitsulo. Mayiko ena ndi zigawo kwenikweni amatchedwa 1008, 1015, 1018, 1022, etc. (Zindikirani: Kubowola mchirazomangiraNthawi zambiri amagwiritsidwa ntchito 1022 zopangira.)

(2) sing'anga mpweya zitsulo 0,25% 0,60%. Panopa pamsika kwenikweni palibe ntchito za nkhaniyi.

(3) aloyi zitsulo: mu wamba mpweya zitsulo kuwonjezera zigawo zikuluzikulu aloyi, kuwonjezera makhalidwe apadera pa zomangamanga zitsulo: monga 35, 40 chromium-molybdenum, SCM435, 10B38. 12.9 kalasi zomangira pogwiritsa ntchito SCM435 chromium-molybdenum aloyi zitsulo, zigawo zikuluzikulu ndi C, Si, Mn, P, S, Cr, Mo.

2. Chitsulo chosapanga dzimbiri. Khalidwe kalasi: 45, 50, 60, 70, 80. makamaka anawagawa martensite (18% Cr, 8% Ni) kutentha kukana zabwino, kukana dzimbiri. a1, a2, a4 martensite (13% Cr) kukana dzimbiri kocheperako, mphamvu yayikulu, kukana kwabwino kovala. c1, c2, c4430 chitsulo chosapanga dzimbiri. 18% Cr kukhumudwitsa ndikwabwino, kukana dzimbiri ndikwamphamvu kuposa austenite. Zopangira zamakono zamakono zimagawidwa makamaka SUS302, SUS304, SUS316 ndi giredi.

3. Mkuwa. Zida wamba zamkuwa, zofiirira zamkuwa aloyi. Msikawu nthawi zambiri umagwiritsidwa ntchito H62, H65, H68 mkuwa pazinthu wamba.

4. Aluminiyamu kachulukidwe aloyi ndi otsika, koma compressive mphamvu ndi mkulu kwambiri, pafupi kapena kuposa kutentha zosagwira kuponyedwa chitsulo, plasticity wabwino, akhoza kukhala zosiyanasiyana mbiri zotayidwa, ndi madutsidwe wabwino magetsi, kutengerapo kutentha ndi dzimbiri. kukana, ntchito mafakitale ndi yaikulu kwambiri, kuchuluka kwa chitsulo chachiwiri.

1. Aloyi zitsulo amatanthauzanso chromium-molybdenum aloyi zitsulo, monga SCM435, etc.
