Iindaba

Okwangoku, i-fasteners kwimarike ikakhulu ziquka intsimbi engatyiwa, carbon steel, ubhedu, ialluminiyam ialloy ezine iintlobo zemathiriyeli ekrwada..

1. Intsimbi yekhabhoni. Ukuya kwi-carbon steel material ekubunjweni kwekhabhoni ukwahlula phakathi kwentsimbi ephantsi ye-carbon, i-medium carbon steel, i-carbon steel ephezulu kunye ne-alloy iron yayo.

(1) intsimbi yekhabhoni ephantsi C%≤ I-0.25% yaseTshayina ngokuqhelekileyo ibizwa ngokuba yintsimbi ye-A3. Amanye amazwe kunye nemimandla ngokusisiseko ibizwa ngokuba yi-1008, 1015, 1018, 1022, njl. (Qaphela: Ukubhoboza umsilaizikrufuzisetyenziswa ngokubanzi 1022 imathiriyeli ekrwada.)

(2) intsimbi yekhabhoni ephakathi 0.25% 0.60%. Okwangoku kwimarike ngokusisiseko akukho ukusetyenziswa kwesi sixhobo.

3 Izikrini ze-12.9 zebakala zisebenzisa i-SCM435 chromium-molybdenum alloy steel, amacandelo aphambili yi-C, Si, Mn, P, S, Cr, Mo.

2. Intsimbi engenasici. Ibakala uphawu: 45, 50, 60, 70, 80. ikakhulu yahlulwe martensite (18% Cr, 8% Ni) ukumelana lobushushu elungileyo, ukumelana umhlwa elungileyo. i-a1, i-a2, i-a4 martensite (i-13% ye-Cr) i-corrosion resistance resistance, amandla aphezulu, ukumelana nokunxiba kakuhle. c1, c2, c4430 steel stainless. I-18% i-Cr upsetting ingcono, ukuxhathisa kwe-corrosion kunamandla kune-austenite. Imathiriyeli ekrwada yemarike yangoku yahlulwe ikakhulu kwi-SUS302, SUS304, SUS316 ngokwebakala.

3. Ubhedu. Izinto eziqhelekileyo zobhedu, i-alloy copper emfusa. Imarike isetyenziswa ngokubanzi i-H62, i-H65, i-H68 yobhedu kwiimveliso eziqhelekileyo.

4. Uxinaniso lwe-aluminiyam ye-alloy luphantsi, kodwa amandla oxinzelelo aphezulu kakhulu, asondele okanye angaphezulu kwentsimbi ekwazi ukumelana nobushushu, iplastiki elungileyo, inokwenziwa kwiiprofayili ezahlukeneyo ze-aluminiyam, kunye nokuhanjiswa kombane okuhle, ukuhanjiswa kobushushu kunye nokuhlwa. ukumelana, ukusetyenziswa kwemizi-mveliso kubanzi kakhulu, inani lentsimbi yesibini kuphela.

1. Insimbi ye-alloy iphinda ibhekisele kwintsimbi ye-chromium-molybdenum alloy, njenge-SCM435, njl.
