Peb paub qhov txawv ntawm cov pa roj carbon tsawg, nruab nrab carbon steel, siab carbon steel thiab alloy steel raws li cov ntsiab lus carbon hauv cov hlau.
1 Tsawg carbon steel C% ≤ 0.25% feem ntau hu ua A3 steel hauv Suav teb. Nws yog lub hauv paus hu ua 10081015181022 txawv teb chaws. Nws yog tsuas yog siv rau Qib 4.8 bolts,gr4 vaj, me me screws thiab lwm yam khoom uas tsis muaj hardness yuav tsum tau. (Ceeb Toom: 1022 cov khoom siv feem ntau yog siv rau cov ntsia hlau drilling.) Cov khoom no tsis haum rausiab zog bolts.
2.Medium carbon steel> 0.25%, C1035 35 #, 35ACR, nws yog rauQib 8.8 hex boltsqhov ntau thiab tsawg, tab sis rau qhov loj thiab qhov kub forged, nws tsis tuaj yeem siv.
3 High carbon steel C%> 0.45%. Feem ntau, cov hlau no yog raugr8.8 ua, kub forged qhov ntau thiab tsawg.
4 Alloy steel: alloy cov ntsiab lus tau ntxiv rau cov pa roj carbon monoxide kom nce qee cov khoom tshwj xeeb ntawm cov hlau, xws li 40Cr, 35CrMo, 42CrMo., SCM435, 10B38. Fangsheng screws yog tsim los ntawm SCM435 chrome molybdenum alloy steel, feem ntau yog tsim los ntawm C, Si, Mn, P, S, Cr thiab Mo. Peb lub tuam txhab siv 40Cr lossis 35CrMo los ua kev zoo siab10.9 hli, 42CrMo, SCM435 los tsimGr12.9 hli.
Yog tias lub Hoobkas siv cov khoom siv tsis raug, lawv yuav ua tsis tiav cov qib uas xav tau hauv cov txheej txheem ntawmKev kho cua sov, thiab qhov zoo yuav tsis tsim nyog
Ningbo Zhongli bolts manufacturing Co., Ltdtau tsim nyob rau hauv 2003, uas yogkev bolts tsum nyob rau hauv Suav teb. Nws muaj zog techincal thiab ntau pab pawg nyob rau hauv ntau xyoo dhau los, Zoo yog zoo heev thiab ruaj khov, nws mas cov khoom yog siab zog DIN thiab ANSI txheem siab bolts, Hex ceev, dawb washers.
